The tilt of Earth’s rotational axis toward or away from the sun causes :
Global warming 🤔
❌❌ Incorrect ❌❌
Daylight savings time 🤔
❌❌ Incorrect ❌❌
24-hour days🤔
❌❌ Incorrect ❌❌
Seasons 🤔
✅✅ Correct !!
Earth’s axial tilt, which always points in the same direction during
Earth’s orbit of the sun, results in the Northern Hemisphere tilting
toward the sun from June to August. In the same manner, the Southern
Hemisphere tilts toward the sun from December to February. Summer takes
place when a hemisphere tilts toward the sun, and winter takes place when
a hemisphere tilts away from the sun.
| Trophic Level | Where It Gets Food | Example |
|---|---|---|
| 1st Trophic Level: Primary Producer |
Makes its own food | Plants make food |
| 2nd Trophic Level: Primary Consumer |
Consume Producers | Mice eat plant seeds |
| 3rd Trophic Level: Secondary Consumer |
Consume Primary Consumers | Snakes eat mice |
| 4th Trophic Level: Tertiary Consumer |
Consume Secondary Consumers | Hawks eat Snakes |
Based on the table, which of the following animals would be classified as a tertiary consumer ?
Deer 🤔
❌❌ Incorrect ❌❌
Anteater 🤔
❌❌ Incorrect ❌❌
Squirrel 🤔
❌❌ Incorrect ❌❌
Great white shark 🤔
✅✅ Correct !!
According to the table, tertiary consumers
acquire their food from secondary consumers. Tertiary consumers are the
top predators in the food chain; an example is the great white shark.
Another way to solve this problem is by process of elimination. Deer eat
grass and other foliage, making them primary consumers; anteaters eat
ants, which eat small particles of vegetation, making anteaters secondary
consumers; squirrels eat nuts, making them primary consumers. Therefore,
the only reasonable answer is the great white shark.
White-nose syndrome is an emerging disease that affects North American bats. The disease is named for a white fungal growth around the muzzles and the wings of hibernating bats. It was first identified in 2006 in a cave in New York State, but it has since spread rapidly across the United States. No treatment is known and some species have declined by more than 90% as a result of the disease.
The Kentucky State Park is very concerned about the health of their 6 bat colonies and began counting the bats in each colony once a year. Below are the results for 2019, 2020, and 2021.White-nose syndrome is an emerging disease that affects North American bats.

What was the mean number of bats in 2020 for the six colonies in the park ?
338 🤔
✅✅ Correct !!
The arithmetic mean, also known as the average,
is a way to describe the center of a data set. It is calculated by summing
the data points of a data set and dividing by the total number of data
points in the set. In this case, the number of bats counted in 2020, which
contains 6 data points, is the data set. Add together the individual
numbers of bats and divide by 6 to calculate the mean number:
Mean = (562 + 102 + 600 + 156 + 205 + 403) ÷ 6
Mean = 2028 ÷ 6

How is energy obtained by primary producers ?
Photosynthesis 🤔
✅✅ Correct !!
Primary producers, such as plants, process
light energy via photosynthesis to form ATP, which can then be used as
chemical energy. Primary, secondary, and tertiary consumers must rely on
energy produced by the organisms beneath them in the pyramid; they use
glycolysis, the citric acid cycle, and oxidative phosphorylation to
produce ATP from the glucose molecules they consume.

The Grand Canyon, located in the Grand Canyon National Park in Arizona, was created approximately 5 million years ago from the Colorado River. The Grand Canyon is 277 miles long, up to 18 miles wide, and reaches a depth of over a mile.
What interaction between Earth’s systems was most likely responsible for the creation of this landmark?
Erosion of rock from water 🤔
✅✅ Correct !!
The Grand Canyon is a prime example of erosion
likely resulting from the passage of water. Wind abrasion would be able to
wear down weak structures, such as those made of sandstone, but would do
little to severely impact compacted earth. Landslides impact temperate,
rainy climates and would not play a part in the desert of Arizona.
Tectonic fissures, or earthquakes, can create sinkholes and other gaps in
solid land, but could not create something as large as the Grand Canyon.

I. Increasing the temperature of Solvent A allows all dissolvable solutes to dissolve faster.
II. Substance A is dissolvable in Solvent A, while Substance B is not.
Given these two hypotheses, which of the following is most likely to be true ?
Substance A will dissolve faster in Solvent A at higher temperatures 🤔
✅✅ Correct !!
Substance A will dissolve faster in Solvent A
at higher temperatures. This statement is true based on the transitive
relation of the two hypotheses. As stated in hypothesis II, Substance B
will not dissolve in Solvent A, regardless of the temperature. Substance A
will dissolve in Solvent A, therefore the only possible choice is that
Substance A will dissolve faster in Solvent A at higher temperatures,
which is supported by hypothesis I.
Substance B will dissolve slower in Solvent A at higher temperatures 🤔
❌❌ Incorrect ❌❌
Substance B will dissolve slower than Substance A in Solvent A, regardless of the temperature of the solution 🤔
❌❌ Incorrect ❌❌
Substance A and Solvent A will not form a solution at any temperature 🤔

When a person reaches out and touches a hot pan, the __________ system is triggered and activates the __________ system to move the hand away. Fill in the blanks.
skeletal, muscular 🤔
❌❌ Incorrect ❌❌
muscular, nervous 🤔
❌❌ Incorrect ❌❌
nervous, endocrine 🤔
❌❌ Incorrect ❌❌
nervous, muscular🤔
✅✅ Correct !!
The nervous system triggers the muscular system
to move the hand away. The nervous system is responsible for communication
between the different body systems. In the example provided, the nervous
system activates first and sends a signal to the muscles to move in order
to avoid damaging the body. The muscular system is responsible for
movement, the skeletal system provides structure to the body, and the
endocrine system is responsible for regulating hormones within the body.
In mice, grey fur color is dominant to white fur color. Two mice mate and produce offspring; the female mouse has the genotype (gg) which results in white fur color, while the male mouse has the genotype (Gg) which results in grey fur color.
Use the Punnett square to calculate the probability that these two mice will produce an offspring with white fur.
25% 🤔
❌❌ Incorrect ❌❌
50% 🤔
✅✅ Correct !!
There is a 50% probability that the offspring
from a white (gg) mouse and a grey (Gg) mouse will have white fur (gg).
The complete Punnett square shows that the chance of the offspring having
the genotype which produces the phenotype for white fur is 2/4 or 50%. The
other 50% of the time results in the genotype of (Gg), which is the
phenotype for grey fur.

The oceans on earth experience tides, waves, and currents. These factors change how humans experience the ocean and impact how ocean water interacts with land. Tides are changes in the sea levels of the ocean that occur periodically.
Which of the following is the cause of ocean tides?
The gravitational pull of the moon on planet Earth 🤔
✅✅ Correct !!
The gravitational pull of the moon on the Earth
is what causes periodic changes in sea levels, also known as tides.
Varying wind intensity can cause waves in ocean waters, but is not strong
enough to influence the tides. Density differences in seawater can cause
ocean currents. Movement of tectonic plates in the ocean can cause
large-scale ocean related disasters such as tsunamis. Neither density
differences nor tectonic plate movement are strong or consistent enough to
influence tides.

Yellowstone National Park is known for its unique population of animals and diverse landscapes. The Rocky Mountain wolf has kept a long-lasting predator-prey relationship with the deer in the park. Over the last few years, Grey wolves have been reintroduced to diversify the animal population.
| Number of Grey Wolves | Number of Deer | Number of Rocky Mountain Wolves |
|---|---|---|
| 300 | 10,000 | 5,000 |
| 400 | 9,800 | 4,900 |

| 1,400 | 8,700 | 3,500 |
| 1,800 | 8,500 | 3,000 |
Based on the chart above what is the relationship between the Rocky Mountain and Grey wolf ?
Mutualism 🤔
❌❌ Incorrect ❌❌
Competition 🤔
✅✅ Correct !!
As you can see from the chart, the population
sizes of both the Rocky Mountain wolf and their deer prey decreased with
the introduction, and increasing population size, of the Grey wolf. From
this it can be concluded that the Rocky Mountain and Grey wolf compete for
their deer prey.
Mutualism is a relationship in which both members of the interacting
populations benefit. If the wolf species had a mutualistic relationship it
would be surprising to see a decline in the size of the Rocky Mountain
wolf population. Neither of the wolf species are expected to, usually,
prey on the other. In a commensalistic relationship one member of the
interacting populations benefits and the other is unaffected, the chart
indicates that with the introduction of the Grey wolf the Rocky Mountain
wolf population declines.

A seesaw is an example of what type of simple machine?
A wedge 🤔
❌❌ Incorrect ❌❌
A pulley 🤔
❌❌ Incorrect ❌❌
A lever 🤔
✅✅ Correct !!
A seesaw is an example of a lever because it is
made up of a bar and a fulcrum. A wedge or incline plane is a triangular
machine that enables less force to be applied over a longer distance to
perform the same amount of work. A pulley is a machine made up of two or
more wheels that increases mechanical advantage when lifting objects with
a rope. Pulleys and levers can be combined to further increase mechanical
advantage. A seesaw is a lever that does not include a pulley.

DNA is an abbreviation for deoxyribonucleic acid. DNA is hereditary material that contains the instructions an organism needs to develop, live, and reproduce. Information is stored in DNA as a code that is made up of four chemical bases: adenine, guanine, cytosine, and thymine. The sequence of these bases determines the information available for building an organism.
DNA can best be compared to :
The person making a smoothie. 🤔
❌❌ Incorrect ❌❌

What numbers are needed in the blank spaces to balance the chemical
equation ?
S8 + __F2 → __SF6
5, 8 🤔
❌❌ Incorrect ❌❌
24, 8 🤔
✅✅ Correct !!
Due to the law of conservation of matter, the
number of sulfur and fluorine molecules on each side of the reaction must
be equivalent. Therefore, the S8 on the reactant side of the equation
necessitates 8 SF6 molecules on the product side.
Doing so
generates a total of 6 × 8 = 48 fluorine molecules on the product side
that must be balanced on the reactant side. It is given that fluorine
reacts as F2, and we know that 48 total fluorine atoms are necessary;
dividing 48 by 2 gives the correct coefficient for the reacting F2.

Use Newton’s second law to find the initial acceleration of an object with
a mass of 40 kg when a force of 6 N is applied. For this problem ignore
direction and round to the nearest hundredth.
Newton’s second law: F = ma
34.7 m/s2 🤔
❌❌ Incorrect ❌❌
25.5 m/s2 🤔
❌❌ Incorrect ❌❌
2.55 m/s2 🤔
❌❌ Incorrect ❌❌
0.15 m/s2 🤔
✅✅ Correct !!
The solution is found by manipulating Newton’s
second law to solve for acceleration, a = F ÷ m. By plugging the numbers
given into the aforementioned equation, the result is:
6 N ÷ 40 kg = 0.15 m/s2
Recall that the Newton is defined as kg * m/s2, so dividing both sides by
the mass, in kg, results in units of m/s2, noticing this helps us verify
that we have correctly solved for the acceleration, which has units of
m/s2.
A study was carried out involving the heart rates of 2 subjects, one with previous cycling training and one who self-reported living a sedentary lifestyle. The subjects’ heart rates were measured during 15 minutes of cycling. The graph below depicts the heart rate of each individual as the work rate increased.
Which of the following conclusions can be inferred from the data depicted in the graph?
The heart rate of the untrained individual was greater than the heart rate of the trained individual throughout the experiment. 🤔
✅✅ Correct !!
Notice that at every value along the x-axis,
the heart rate of the untrained participant is higher than the heart rate
of the trained participant. From this, only the first answer choice can be
inferred.
The heart rate of the trained individual was greater than the heart rate of the untrained individual throughout the experiment. 🤔
❌❌ Incorrect ❌❌
The heart rate of the trained individual increased at a faster rate than that of the untrained individual as the work rate increased. 🤔

Which of these statements about photosynthesis is true ?
6 molecules of carbon dioxide plus 12 molecules of water will produce 2 molecules of sugar plus 6 molecules of oxygen 🤔
❌❌ Incorrect ❌❌
12 molecules of carbon dioxide plus 12 molecules of water will produce 2 molecules of sugar plus 12 molecules of oxygen 🤔
✅✅ Correct !!
The equation shows that exactly 6 molecules of
carbon dioxide will react with exactly 6 molecules of water in the
presence of light to produce exactly 1 molecule of sugar and 6 molecules
of diatomic oxygen. As a result of the law of conservation of matter, the
correct answer will maintain the ratio of reactants to products given in
the original equation.
Only the second answer choice gives an
equation that is proportional to the original equation: the coefficient of
each reactant is doubled, so the coefficient of each product is also
doubled. The other answer choices all incorrectly alter the ratios of
products to reactants and violate the law of conservation of matter.
1 molecule of sugar plus 6 molecules of oxygen will produce 6 molecules of water plus 6 molecules of carbon dioxide 🤔

Sustainable agriculture is the act of farming using principles of ecology, the study of relationships between organisms and their environment. Unsustainable agriculture involves practices that can cause long-term damage to soil over time. This includes too much tillage that can lead to erosion, as well as irrigation without adequate drainage (leading to salinization). Long-term experiments have provided some of the best data on how various practices affect soil properties essential to sustainability.
In the United States, the USDA-Natural Resources Conservation Service specializes in providing technical and financial assistance for those interested in pursuing natural resource conservation and production agriculture as compatible goals. The most important factors for an individual farm are sun, air, soil, nutrients and water. Of the four, water and soil quality and quantity are most amenable to human intervention through time and labor.
Which sentence from the paragraph supports the idea that specific farming techniques used by humans are responsible for the environmental damage caused by unsustainable agriculture ?
“Sustainable agriculture is the act of farming using principles of ecology, the study of relationships between organisms and their environment.” 🤔
❌❌ Incorrect ❌❌
“Unsustainable agriculture involves practices that can cause long-term damage to soil over time.” 🤔
❌❌ Incorrect ❌❌
“This includes too much tillage that can lead to erosion, as well as irrigation without adequate drainage (leading to salinization).” 🤔
✅✅ Correct !!
Both “too much tillage” and “irrigation without
adequate drainage” are actions performed by human beings, and indicate
that humans are responsible for damaging land beyond sustainability.

As part of a study on how skin type and redness correlate when exposed to different amounts of UV light, a scientist set up an experiment to see how much redness occurred on various skin types.
The scientist classified 100 people into six different categories of skin type, then exposed them to increasingly higher doses of UV light and recorded the level of redness that appeared on the skin.
Which is an independent variable and which is a dependent variable in this experiment ?
An independent variable is the skin type; a dependent variable is the amount of UV light. 🤔
❌❌ Incorrect ❌❌
An independent variable is the redness; a dependent variable is the amount of UV light. 🤔
❌❌ Incorrect ❌❌
An independent variable is the amount of UV light; a dependent variable is the skin type. 🤔
❌❌ Incorrect ❌❌
An independent variable is the skin type; a dependent variable is the redness. 🤔
✅✅ Correct !!
In an experiment, scientists use both
independent and dependent variables. An independent variable is the
variable that is changed by the scientists in an experiment to test the
effects on the dependent variable.
A dependent variable is the
variable being measured. In this study, the scientist controls two
variables: the skin type and the UV light. The dependent variable is the
level of redness on the skin.

Cold brew coffee is one of the fastest growing trends in coffee houses across the USA. It is typically made by mixing fresh ground coffee with cold water and letting it brew for 12 to 24 hours. One coffee house came up with the idea of injecting nitrous gas into the cold brewed coffee, thinking that it might improve the taste.
As they tried out this new idea, they found out that the pressure of the nitrous gas had a dramatic effect on the flavor of the coffee. At that point they decided to run an experiment with 3 batches of coffee, in an effort to find the amount of pressure that produces the best tasting coffee. The chart provided shows the procedures that they followed for each of the batches.
| Batch #1 | Batch #2 | Batch #3 | |
|---|---|---|---|
| Amount of Coffee | 12 ounces | 12 ounces | 12 ounces |
| Amount of Water | 3 cups | 3 cups | 3 cups |
| Amount of Time | 12 hours | 18 hours | 24 hours |
| Amount of Gas | 35 PSI | 45 PSI | 55 PSI |
What was the error in the design of their experiment ?
The coffee house should have used more than 12 ounces of coffee. 🤔
❌❌ Incorrect ❌❌
The coffee house should have used a set amount of time for brewing. 🤔
✅✅ Correct !!
By changing two of the variables, time of brew
and pressure of nitrous gas, the brewers will be unable to tell which
variable leads to a tastier coffee.
If they want to try
different brew times, then they should do so in a separate experiment that
uses a constant pressure of nitrous gas.
The coffee house should have brewed at least 4 batches. 🤔
❌❌ Incorrect ❌❌
The coffee house should have tried several different types of gases. 🤔

Two objects on Earth are dropped from the top of a building that is 70 meters high. Object A has a mass of 12 g and object B has a mass of 6 kg. Assuming there is no air resistance, which object will hit the ground first ?
Object A 🤔
❌❌ Incorrect ❌❌
Object B 🤔
❌❌ Incorrect ❌❌
Both objects will hit the ground at the same time 🤔
✅✅ Correct !!
Without air resistance, the only force acting
on the two objects is Earth’s gravitational field. Consequently, the
acceleration of both object A and object B is independent of mass, and
every second, both velocities will increase by 9.8 meters per second.
Given
that both objects are dropped from the same height, and they both travel
at the same rate, they will both hit the ground at the same time.
There is not enough information to determine which object will hit the ground first 🤔

A lake contains many fish that local bears depend on as their major source
of food.
What would be the consequence of an algal bloom killing off
a large portion of the fish population ?
The number of bears in the area would increase 🤔
❌❌ Incorrect ❌❌
The number of bears in the area would decrease 🤔
✅✅ Correct !!
The number of bears in the area would decrease
due to the death of the fish which serves as their major food source. The
decrease in the number of fish would either cause the bears to die off, to
more fully exploit another food source in the area, or to find a new
source of food elsewhere.
An increase in the bear population
would not be a proper relationship because the bear population relies upon
the fish population for its survival. From the information provided, it
cannot be concluded that the bears would go into hibernation.
The number of bears in the area would be unaffected 🤔
❌❌ Incorrect ❌❌
The bears would go into hibernation 🤔

Researchers have created a formula for predicting the impact of population growth on the environment :
E = (P x N) ÷ T
Where E is environmental impact, P is population, N is energy demand, and T is development of new technology.
Based on this equation, in order to sustain population growth and maintain environmental impact, what factor must change at a rate equal to the rate of population growth ?
An increase in technology 🤔
✅✅ Correct !!
Notice that environmental impact, E, is
positively correlated with both population, P, and energy demand, N, and
it is inversely correlated to development of new technology, T. This means
that if population or energy demand doubles, environmental impact will
double as well. It also means that if development of new technology
doubles, environmental impact will decrease by half.
Two cases
will maintain environmental impact if population increases: a proportional
decrease in energy demand, or a proportional increase in development of
new technology. Of these possibilities, only the second option, an
increase in technology, is an available answer choice.

Two mice mate and produce offspring. Both of the mice have the genotype (Gg) which is the phenotype for grey fur color. Use a Punnett square to calculate the probability that these two mice will produce an offspring with white fur (gg).
25%🤔
✅✅ Correct !!
The complete Punnett square shows that the
chance of the individual having the genotype (gg) which produces the
phenotype for white fur is 1 in 4, or 25%. Half of the offspring, 2 out of
4, will have the genotype of (Gg), which is the heterozygous phenotype for
grey fur.
Another quarter of the offspring will have the
genotype (GG), which is homozygous dominant, meaning they will also have
grey fur.

Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
Which of the following describes the feedback method used by a healthy human to regulate body temperature first in warm surroundings and then in cold surroundings ?
When body temperature is too cold, the body starts sweating in order to cool down; when body temperature is too hot, the body starts shivering in order to warm up 🤔
❌❌ Incorrect ❌❌
When body temperature is too high, the body starts shivering in order to warm up; when body temperature becomes too low, the body starts sweating in order to cool down 🤔
❌❌ Incorrect ❌❌
When body temperature is too cold, the body starts shivering in order to warm up; when body temperature is too hot, the body starts sweating in order to cool down 🤔
❌❌ Incorrect ❌❌
When body temperature is too high, the body starts to sweat in order to cool; when the body temperature becomes too low, the body starts shivering in order to warm up 🤔
✅✅ Correct !!
The body first has to process that there is a
need to change and then must properly signal the correct change given the
situation. Sweating serves as a cooling mechanism by eliminating heat
through evaporation. Shivering generates thermal energy through the small,
rapid mechanical motions of muscle.
