$$\text{Metabolic rate} \propto \text{body mass}^{0.75}$$

Question 1

Which of the following best describes the difference between anatomy and physiology in animal biology?

Accepted Answer

Anatomy is the study of biological structure, while physiology is the study of function and processes within those structures.

Question 2

Which tissue type is primarily responsible for rapid transmission of signals throughout the animal body?

Accepted Answer

Nervous tissue

Question 3

A small mammal has a higher basal metabolic rate per gram of body mass compared to a large mammal. Which equation best represents the relationship between metabolic rate and body size?

Accepted Answer

$$	ext{Metabolic rate} \propto 	ext{body mass}^{0.75}$$

Question 4

Which of the following is a correct example of negative feedback in animal physiology?

Accepted Answer

When blood glucose rises, insulin is released to lower glucose levels back to normal.

Question 5

Which organ system is responsible for transporting hormones throughout the body for gradual changes such as growth and development?

Accepted Answer

Endocrine system

Question 6

Which of the following statements about homeostasis is TRUE?

Accepted Answer

Homeostasis involves keeping internal variables within a set point despite external changes.

Question 7

Which process in the digestive system is responsible for the chemical breakdown of macromolecules into absorbable units?

Accepted Answer

Digestion

Question 8

A patient is unable to digest proteins efficiently due to a lack of pepsin. In which part of the digestive tract does this deficiency primarily affect protein digestion?

Accepted Answer

Stomach

Question 9

Which of the following is a function of the hepatic portal vein in nutrient processing?

Accepted Answer

It carries nutrients absorbed from the digestive tract to the liver for processing.

Question 10

Which adaptation would you expect in the digestive system of a carnivore compared to a herbivore?

Accepted Answer

Large expandable stomach for storing prey

Question 11

Which of the following is an essential amino acid for animals?

Accepted Answer

Leucine

Question 12

Which mechanism allows aquatic animals to maximize the rate of gas exchange with their environment?

Accepted Answer

Having highly folded organs to increase surface area

Question 13

Which of the following is a correct example of acclimatization in animals?

Accepted Answer

A bird growing thicker feathers in winter to retain heat

Question 14

Which of the following best describes the role of countercurrent exchange in thermoregulation?

Accepted Answer

It enables arteries and veins to exchange heat, conserving core body temperature.

Question 15

Which of the following is TRUE about endothermic animals?

Accepted Answer

They maintain stable body temperature even when environmental temperature changes.

Question 16

Which process is responsible for moving food through the esophagus to the stomach?

Accepted Answer

Peristalsis

Question 17

Which of the following is a correct sequence of organization in animal bodies?

Accepted Answer

Cells → tissues → organs → organ systems

Question 18

Which of the following is a function of the large intestine in vertebrates?

Accepted Answer

Complete recovery of water and formation of feces

Question 19

Which of the following is a plausible consequence of a diet lacking essential amino acids?

Accepted Answer

Muscles shrink and brain function becomes deficient

Question 20

Which of the following best explains why small animals have higher metabolic rates per gram than large animals?

Accepted Answer

Small animals have a greater surface area to volume ratio, leading to faster heat loss and higher energy demand.
