Question 1

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

Accepted Answer

Anatomy is the study of the structure of body parts, and physiology is the study of how those parts function; understanding structure helps explain function and vice versa.

Question 2

Arrange the following levels of structural organization in the correct order from simplest to most complex: 1) Organ, 2) Cellular, 3) Chemical, 4) Organismal, 5) Tissue, 6) System.

Accepted Answer

3, 2, 5, 1, 6, 4

Question 3

Which of the following is NOT a component of a typical feedback system?

Accepted Answer

Stimulus

Question 4

A patient is given a solution with a pH of 3. Which of the following statements is correct regarding the solution?

Accepted Answer

It is acidic and has a high hydrogen ion concentration.

Question 5

Which of the following best explains why sodium chloride ($$\mathrm{NaCl}) $$dissolves in water, but oil does not?

Accepted Answer

$$\mathrm{NaCl}$$ forms ionic bonds, which interact with water's polarity, while oil is nonpolar and cannot interact with water's polar molecules.

Question 6

Which organelle is primarily responsible for ATP production in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 7

A red blood cell is placed in a solution and swells until it bursts. Which term best describes the solution, and what is the direction of water movement?

Accepted Answer

Hypotonic; water moves into the cell.

Question 8

Which of the following best describes the difference between simple diffusion and facilitated diffusion across the plasma membrane?

Accepted Answer

Facilitated diffusion requires a protein carrier or channel, while simple diffusion does not.

Question 9

Which of the following is a correct pairing of a serous membrane and its location?

Accepted Answer

Peritoneum – lines the abdominal cavity

Question 10

Which of the following best describes the sodium-potassium pump ($$\mathrm{Na^+/K^+}$$ ATPase)?

Accepted Answer

It is an active transport protein that moves 3 sodium ions out of the cell and 2 potassium ions into the cell using ATP.

Question 11

Which of the following statements about DNA and RNA is correct?

Accepted Answer

DNA is double-stranded and stores genetic information; RNA is single-stranded and involved in protein synthesis.

Question 12

Which of the following best describes the function of enzymes in biological systems?

Accepted Answer

Enzymes lower the activation energy, increasing the rate of chemical reactions.

Question 13

A molecule with the formula $$\mathrm{C$$_{6}$$H_{12}O$$_{6}}$ is classified as which of the following?

Accepted Answer

A monosaccharide

Question 14

Which of the following best describes the anatomical position?

Accepted Answer

Standing upright, facing forward, arms at the sides with palms facing forward, and feet together.

Question 15

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

Accepted Answer

Release of insulin to lower high blood glucose levels

Question 16

Which of the following statements about isotopes and ions is correct?

Accepted Answer

Isotopes have the same number of protons but different numbers of neutrons; ions have gained or lost electrons.

Question 17

Which of the following molecules would most likely require a transport protein to cross the plasma membrane?

Accepted Answer

Glucose

Question 18

Which of the following best describes the difference between primary and secondary active transport?

Accepted Answer

Primary active transport uses ATP directly, while secondary active transport uses the energy stored in an ion gradient.

Question 19

Which of the following best describes the effect of aging on homeostasis?

Accepted Answer

Aging decreases the efficiency of homeostatic mechanisms, increasing susceptibility to disease.

Question 20

Which of the following is the main energy source for all types of diffusion across the plasma membrane?

Accepted Answer

Concentration gradient
