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, while physiology is the study of how those parts function.

Question 2

A patient is experiencing muscle cramps due to an electrolyte imbalance. Which of the following best explains why homeostasis is important in this scenario?

Accepted Answer

Homeostasis maintains stable internal conditions, such as electrolyte levels, which are necessary for normal muscle function.

Question 3

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

Accepted Answer

Blood clotting after a vessel is damaged

Question 4

A solution contains 10 grams of NaCl dissolved in 100 mL of water. What is the percent concentration of NaCl in this solution? Use the formula $$	ext{Percent concentration} = \frac{	ext{mass of solute}}{	ext{volume of solution}} 	imes 100.$$

Accepted Answer

$$10\%$$

Question 5

Which of the following best describes the difference between covalent and ionic bonds?

Accepted Answer

Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons.

Question 6

Which of the following statements about enzymes is correct?

Accepted Answer

Enzymes act as biological catalysts to speed up chemical reactions.

Question 7

A red blood cell is placed in a hypotonic solution. What will happen to the cell, and why?

Accepted Answer

The cell will swell and may burst because water moves into the cell by osmosis.

Question 8

Which of the following best describes the function of buffers in the blood?

Accepted Answer

Buffers prevent drastic changes in pH by neutralizing acids and bases.

Question 9

Which organelle is responsible for producing ATP through cellular respiration?

Accepted Answer

Mitochondrion

Question 10

A cell is observed to have a large number of rough endoplasmic reticulum. What is the most likely function of this cell?

Accepted Answer

Synthesis of proteins for export

Question 11

During which phase of mitosis do the chromosomes align along the center of the cell?

Accepted Answer

Metaphase

Question 12

Which of the following best describes apoptosis?

Accepted Answer

Programmed cell death that is a normal part of development and homeostasis

Question 13

Which of the following is a function of epithelial tissue?

Accepted Answer

Protection, secretion, and absorption

Question 14

A patient has a genetic disorder that affects the structure of collagen. Which tissue type is most likely to be affected?

Accepted Answer

Connective tissue

Question 15

Which of the following best describes the difference between cutaneous, mucous, and serous membranes?

Accepted Answer

Cutaneous membranes cover the body surface, mucous membranes line cavities open to the exterior, and serous membranes line closed ventral body cavities.

Question 16

Which of the following best describes the sodium-potassium ATPase pump?

Accepted Answer

It moves sodium ions out of the cell and potassium ions into the cell using ATP.

Question 17

Which of the following is a characteristic of passive transport across the plasma membrane?

Accepted Answer

It moves substances down their concentration gradient without using cellular energy.

Question 18

Which of the following best describes the function of lysosomes?

Accepted Answer

Question 19

A patient is unable to absorb nutrients properly due to a defect in microvilli. Which cell structure is most likely affected?

Accepted Answer

Microvilli

Question 20

Which of the following best describes the difference between DNA and RNA?

Accepted Answer

DNA stores genetic information, while RNA is involved in protein synthesis.
