Question 1

Which of the following best describes the difference in embryonic development between protostomes and deuterostomes?

Accepted Answer

In protostomes, the blastopore becomes the mouth, while in deuterostomes, it becomes the anus.

Question 2

Which of the following is NOT a characteristic shared by all animals?

Accepted Answer

They have cell walls made of cellulose.

Question 3

Which germ layer gives rise to the lining of the digestive tract and associated organs?

Accepted Answer

Endoderm

Question 4

Which of the following best explains why cell size is limited in animals?

Accepted Answer

As cell size increases, the surface area to volume ratio decreases, limiting efficient exchange of materials.

Question 5

A patient is experiencing frequent, watery bowel movements. Which of the following best explains the physiological cause of this condition?

Accepted Answer

Insufficient water reabsorption in the large intestine.

Question 6

Which of the following feeding strategies is used by earthworms, and what does it involve?

Accepted Answer

Substrate feeding; consuming material in or on which they live.

Question 7

Which of the following best describes the advantage of the villi and microvilli in the small intestine?

Accepted Answer

They increase the surface area for nutrient absorption.

Question 8

Which of the following is the correct sequence of air flow through the mammalian respiratory system?

Accepted Answer

Nasal cavity → pharynx → larynx → trachea → bronchi → bronchioles → alveoli

Question 9

Which of the following best describes the role of transport epithelia in marine bony fish?

Accepted Answer

They actively excrete excess salts to maintain osmotic balance.

Question 10

Which of the following is a correct statement about the excretion of nitrogenous waste in birds?

Accepted Answer

Birds excrete uric acid, which conserves water and is less toxic than ammonia.

Question 11

Which of the following best describes the process of peristalsis?

Accepted Answer

Waves of smooth muscle contractions that move food along the digestive tract.

Question 12

Which of the following is the correct order of embryonic development in animals?

Accepted Answer

Zygote → blastula → gastrula

Question 13

Which of the following is a function of the nephron's loop of Henle in the mammalian kidney?

Accepted Answer

To concentrate urine by reabsorbing water and salts.

Question 14

Which of the following best describes the difference between simple diffusion and active transport?

Accepted Answer

Simple diffusion moves substances down their concentration gradient without energy; active transport moves substances against their gradient using energy.

Question 15

Which of the following is a correct pairing of animal and its excretory structure?

Accepted Answer

Flatworm – protonephridia (flame bulbs)

Question 16

Which of the following is the first stored fuel used by the body during exercise?

Accepted Answer

Carbohydrates

Question 17

Which of the following best explains why cattle can survive on a plant-based diet?

Accepted Answer

They have symbiotic microorganisms in their digestive tract that help break down cellulose.

Question 18

Which of the following is NOT a function of epithelial tissue in animals?

Accepted Answer

Conducting electrical impulses

Question 19

Which of the following best describes the difference between osmoconformers and osmoregulators?

Accepted Answer

Osmoconformers maintain internal osmolarity equal to their environment; osmoregulators actively control internal osmolarity.

Question 20

Which of the following is the correct sequence of events in the excretory process of the nephron?

Accepted Answer

Filtration → reabsorption → secretion → excretion
