Question 1

Which of the following best describes the function of the nucleolus within the cell nucleus?

Accepted Answer

It is the site of ribosomal RNA synthesis and ribosome assembly.

Question 2

A patient is suffering from dehydration. Which type of solution should be administered intravenously to avoid further cell shrinkage due to osmosis?

Accepted Answer

An isotonic solution

Question 3

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

Accepted Answer

Mitochondria

Question 4

Which of the following best explains why facilitated diffusion requires membrane proteins?

Accepted Answer

Because certain molecules are too large or polar to pass through the lipid bilayer without assistance.

Question 5

Which equation correctly represents the process of osmosis across a semipermeable membrane?

Accepted Answer

$$ J = -P (C_1$ - C_2$) $$

Question 6

Which of the following is NOT a function of the plasma membrane?

Accepted Answer

Synthesizing proteins for export

Question 7

During protein synthesis, which molecule carries the genetic code from the nucleus to the ribosome?

Accepted Answer

Messenger RNA (mRNA)

Question 8

Which tissue type is specialized for rapid communication and control of body functions?

Accepted Answer

Nervous tissue

Question 9

A biopsy reveals cells with abundant rough endoplasmic reticulum. What is the most likely function of these cells?

Accepted Answer

Protein synthesis for secretion

Question 10

Which connective tissue type is found in the walls of large arteries and provides elasticity?

Accepted Answer

Elastic cartilage

Question 11

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

Accepted Answer

The double helix unwinds and each strand serves as a template for a new complementary strand.

Question 12

Which muscle tissue type is under voluntary control and contains striations?

Accepted Answer

Skeletal muscle

Question 13

Which of the following is a hallmark of epithelial tissue?

Accepted Answer

Cells are tightly packed with minimal extracellular matrix.

Question 14

A patient with a genetic defect in lysosomal enzymes is likely to suffer from which cellular problem?

Accepted Answer

Accumulation of undigested cellular debris

Question 15

Which of the following best describes the function of adipose tissue?

Accepted Answer

Energy storage and insulation

Question 16

Which equation best represents the rate of simple diffusion across a membrane?

Accepted Answer

$$ J = D \frac{dC}{dx} $$

Question 17

Which of the following cell organelles is responsible for packaging and modifying proteins for secretion?

Accepted Answer

Golgi apparatus

Question 18

Which tissue type lines the inside of blood vessels and the heart?

Accepted Answer

Simple squamous epithelium

Question 19

Which of the following is a function of smooth muscle tissue?

Accepted Answer

Regulating the diameter of blood vessels

Question 20

Which of the following best describes the role of transfer RNA (tRNA) in protein synthesis?

Accepted Answer

It brings amino acids to the ribosome and matches them to the coded mRNA message.
