$$\text{Metabolic rate} = m$$^{3/4}$$

Question 1

Which of the following best describes the relationship between animal form and function?

Accepted Answer

Form and function are correlated at all levels of organization, so examining anatomy often provides clues to physiology.

Question 2

A penguin huddling with others in a cold environment is an example of which thermoregulatory adaptation?

Accepted Answer

Behavioral response

Question 3

Which physical law limits the possible shapes for fast swimming animals in water?

Accepted Answer

Properties of water, such as resistance and viscosity

Question 4

What is the main function of epithelial tissue in animals?

Accepted Answer

Covering the outside of the body and lining organs and cavities

Question 5

Which equation best represents the relationship between metabolic rate and body mass in animals?

Accepted Answer

$$	ext{Metabolic rate} = m$$^{3/4}$$

Question 6

Which organ system is primarily responsible for internal distribution of materials in mammals?

Accepted Answer

Circulatory system

Question 7

A person climbs to high altitude and their body gradually adjusts to the lower oxygen levels. This process is best described as:

Accepted Answer

Acclimatization

Question 8

Which of the following is NOT a main type of animal tissue?

Accepted Answer

Skeletal

Question 9

Which process is responsible for the rapid transmission of information to specific target cells in animals?

Accepted Answer

Nerve impulses in the nervous system

Question 10

Which feedback mechanism is most important for maintaining homeostasis in animals?

Accepted Answer

Negative feedback

Question 11

A digital thermometer reads 98.6°F. What is the equivalent temperature in Celsius? Use the formula $$C = \frac{5}{9}(F - 32).$$

Accepted Answer

$$37.0\ ^\circ C$$

Question 12

Which adaptation allows marine mammals to minimize heat loss in cold water?

Countercurrent heat exchange

Question 13

Which of the following is a real-life example of negative feedback in humans?

Accepted Answer

Regulation of blood glucose levels by insulin

Question 14

Which tissue type contains cells called fibroblasts and macrophages?

Accepted Answer

Connective tissue

Question 15

Which of the following is true about basal metabolic rate (BMR) in endotherms?

Accepted Answer

BMR is measured at rest, with an empty stomach, and not experiencing stress.

Question 16

Which of the following is a consequence of the higher metabolic rate per gram in smaller animals?

Accepted Answer

Higher breathing rate, heart rate, and greater relative blood volume

Question 17

Which process is used to measure the metabolic rate of a swimming shark, as shown in the image?

Accepted Answer

Measuring the rate of oxygen consumption

Question 18

Which hormone is most likely to be involved in circadian rhythm regulation, as shown in the graph?

Accepted Answer

Question 19

Which of the following is an example of acclimatization in thermoregulation?

Accepted Answer
