Question 1

Which of the following best describes the relationship between anatomy and physiology?

Accepted Answer

Anatomy studies the structure of body parts, while physiology studies their function.

Question 2

A patient has a mutation that causes their bones to be soft and flexible. Which principle does this scenario best illustrate?

Accepted Answer

Complementarity of structure and function

Question 3

Arrange the following levels of body organization from smallest to largest: organelle, molecule, cell, atom.

Accepted Answer

Atom, molecule, organelle, cell

Question 4

Which of the following is an example of negative feedback in the human body?

Accepted Answer

Sweating to cool the body when overheated

Question 5

A thermostat in a room is often used as an analogy for which physiological concept?

Accepted Answer

Negative feedback

Question 6

Which of the following best describes positive feedback?

Accepted Answer

The response enhances the original stimulus, leading to a greater response.

Question 7

Which of the following is the correct order of body organization, starting from the simplest to the most complex?

Accepted Answer

Atom, molecule, organelle, cell, organ, organ system, organism

Question 8

Which of the following is an example of the complementarity of structure and function?

Accepted Answer

Flat back teeth are adapted for grinding food due to their broad surface.

Question 9

A person is exposed to cold temperatures. Their body responds by shivering to generate heat. Which feedback mechanism is at work?

Accepted Answer

Negative feedback

Question 10

Which of the following best defines homeostasis?

Accepted Answer

The ability to maintain relatively stable internal conditions despite external changes.

Question 11

Which of the following is NOT an example of an organelle?

Accepted Answer

Hydrogen

Question 12

A patient is experiencing a rapid increase in blood clotting after a small injury, which leads to even more clotting. This is an example of:

Accepted Answer

Positive feedback

Question 13

Which of the following best illustrates the concept of dynamic equilibrium in homeostasis?

Accepted Answer

Body temperature fluctuates slightly around a set point.

Question 14

If the output of a system shuts off the original effect of the stimulus, which type of feedback is this?

Accepted Answer

Negative feedback

Question 15

Which of the following is the best example of an organ system?

Accepted Answer

Cardiovascular system

Question 16

A scientist is studying how the sharpness of a cat’s front teeth allows it to cut into food. Which concept is being demonstrated?

Accepted Answer

Complementarity of structure and function

Question 17

Which of the following is a molecule, not an atom or organelle?

Accepted Answer

CO$$_2$$

Question 18

Which of the following scenarios best demonstrates the principle 'form determines function'?

Accepted Answer

Bones are hard, which allows them to support the body.

Question 19

Which of the following is the correct sequence for the levels of organization in the human body, from simplest to most complex?

Accepted Answer

Atom $$\rightarrow$$ molecule $$\rightarrow$$ organelle $$\rightarrow$$ cell $$\rightarrow$$ tissue $$\rightarrow$$ organ $$\rightarrow$$ organ system $$\rightarrow$$ organism

Question 20

A person’s blood sugar rises after eating, and insulin is released to lower it back to normal. Which type of feedback is this?

Accepted Answer

Negative feedback
