$\text{Metabolism} = \text{Catabolism} + \text{Anabolism}$

Question 1

Which of the following best describes the principle of complementarity of structure and function?

Accepted Answer

Function always reflects structure; what a structure can do depends on its specific form.

Question 2

A patient is unable to maintain a stable internal body temperature. Which homeostatic component is most likely malfunctioning?

Accepted Answer

Control center

Question 3

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

Accepted Answer

Formation of a platelet plug during blood clotting

Question 4

Which level of structural organization is correctly matched with its description?

Accepted Answer

Chemical level: atoms, molecules, and organelles

Question 5

A person is experiencing dehydration. Which survival need is most directly affected?

Accepted Answer

Water

Question 6

Which of the following best illustrates the concept of maintaining boundaries as a necessary life function?

Accepted Answer

The skin preventing the entry of pathogens into the body

Question 7

During exercise, the body increases breathing rate to supply more oxygen to muscles. Which necessary life function does this best represent?

Accepted Answer

Responsiveness

Question 8

Which of the following equations best represents the sum of all chemical reactions in the body (metabolism)?

Accepted Answer

$	ext{Metabolism} = 	ext{Catabolism} + 	ext{Anabolism}$

Question 9

A person has a genetic disorder that prevents the synthesis of certain proteins. Which survival need is most directly impacted?

Accepted Answer

Proteins

Question 10

Which of the following scenarios best demonstrates a negative feedback mechanism?

Accepted Answer

Shivering to increase body temperature when cold

Question 11

If atmospheric pressure drops significantly, which body process is most likely to be directly impaired?

Accepted Answer

Gas exchange in the lungs

Question 12

Which of the following best describes the role of the effector in a homeostatic control system?

Accepted Answer

Provides the means to respond to a stimulus

Question 13

A scientist is studying the microscopic structure of liver tissue. Which subdivision of anatomy is she most likely using?

Accepted Answer

Histology

Question 14

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 15

Which of the following best explains why oxygen is a critical survival need?

Accepted Answer

Oxygen is essential for the release of energy from foods during ATP production.

Question 16

A patient has a condition where their cells cannot divide for growth or repair. Which necessary life function is directly affected?

Accepted Answer

Reproduction

Question 17

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

Accepted Answer

Anatomy and physiology are inseparable; function always reflects structure.

Question 18

Which of the following is an example of a variable that is regulated by homeostatic mechanisms?

Accepted Answer

Blood sugar

Question 19

A person eats a meal high in carbohydrates. Which process will most directly increase as a result?

Accepted Answer

Catabolism

Question 20

Which of the following best describes the function of the control center in a homeostatic system?

Accepted Answer

Determines the set point and appropriate response to a stimulus
