The tilt of Earth’s rotational axis toward or away from the sun causes:

This table describes the 4 trophic levels\(:\)

Based on the table, which of the following animals would be classified as a tertiary consumer?

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.

What was the mean number of bats in 2020 for the six colonies in the park?

Use the energy pyramid to answer the question.

How is energy obtained by primary producers?

What interaction between Earth’s systems was most likely responsible for the creation of this landmark?

Multiple studies have supported the following two hypotheses:

Given these two hypotheses, which of the following is most likely to be true?

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.

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.

Which of the following is the cause of ocean 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.

Based on the chart above what is the relationship between the Rocky Mountain and Grey wolf?

A seesaw is an example of what type of simple machine?

DNA can best be compared to:

What numbers are needed in the blank spaces to balance the chemical equation?

S₈ + __F₂ → __SF₆

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

Enter the acceleration below (in 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 equation provided represents photosynthesis.

Which of these statements about photosynthesis is true?

Peter hypothesizes that if students switch from a cereal breakfast to a high-protein breakfast, their grades will improve. The steps of his experiment are given below. Arrange the steps in the correct order from first to last to give the best experimental design.

The average diameter of a healthy male’s aorta, the largest artery in the body, is 36 mm. If 1 meter is equal to 1000 millimeters, what is the average diameter of the human male’s aorta in meters?
