Question 1

Which of the following best describes the function of aquaporins in the plasma membrane?

Accepted Answer

They facilitate the passive movement of water molecules across the membrane.

Question 2

A red blood cell is placed in a solution and begins to swell and eventually bursts. Which type of solution was the cell placed in, and what is the underlying mechanism?

Accepted Answer

Hypotonic; water moves into the cell by osmosis.

Question 3

Which of the following best represents the correct sequence of events during the cell cycle?

Accepted Answer

Interphase → Prophase → Metaphase → Anaphase → Telophase

Question 4

Which of the following tissue types is primarily responsible for transmitting electrical impulses throughout the body?

Accepted Answer

Nervous tissue

Question 5

A patient is diagnosed with atrophy of the skin. Which of the following best describes this condition?

Accepted Answer

A decrease in the size or wasting away of skin tissue

Question 6

Which of the following best describes the role of mitochondria in the cell?

Accepted Answer

They generate ATP through cellular respiration.

Question 7

A laboratory experiment requires you to distinguish between epithelial and connective tissues under a microscope. Which characteristic would most reliably identify epithelial tissue?

Accepted Answer

Cells are tightly packed with minimal extracellular space

Question 8

Which of the following formulas correctly represents the calculation of osmotic pressure ($$\Pi) $$according to van't Hoff's law?

Accepted Answer

$$\Pi = iMRT$$

Question 9

A patient is suffering from dehydration. Which type of intravenous (IV) solution would be most appropriate to administer to avoid causing lysis or crenation of red blood cells?

Accepted Answer

An isotonic solution

Question 10

Which of the following best describes the function of the dermis in the skin?

Accepted Answer

It contains blood vessels, nerves, and glands that support the epidermis.

Question 11

During active transport, which of the following statements is correct regarding the movement of substances across the plasma membrane?

Accepted Answer

Substances move against their concentration gradient using ATP.

Question 12

Which of the following is a function of the hair in the integumentary system?

Accepted Answer

Protection from UV radiation and minor physical trauma

Question 13

A mutation prevents the formation of microvilli in intestinal epithelial cells. Which of the following would most likely be impaired as a result?

Accepted Answer

Absorption of nutrients

Question 14

Which of the following best describes the process of DNA transcription?

Accepted Answer

The copying of a DNA sequence into an RNA molecule

Question 15

A biopsy sample shows tissue with striated, multinucleated cells. Which tissue type is most likely being observed?

Accepted Answer

Skeletal muscle tissue

Question 16

Which of the following best explains why epithelial tissues are more likely to regenerate quickly after injury compared to connective tissues?

Accepted Answer

Epithelial tissues have a high rate of mitosis.

Question 17

A patient presents with a genetic disorder that affects the function of sodium-potassium pumps in their cells. Which of the following cellular processes would be most directly impaired?

Accepted Answer

Maintenance of the resting membrane potential

Question 18

Which of the following is a primary function of glands found in epithelial tissue?

Accepted Answer

Secretion of substances such as hormones or enzymes

Question 19

Which of the following best describes the difference between interphase and mitosis in the cell cycle?

Accepted Answer

Interphase is when the cell grows and replicates DNA; mitosis is when the cell divides.

Question 20

A patient with a burn that destroys both the epidermis and the entire dermis would be classified as having which type of burn?

Accepted Answer

Third-degree burn
