Question 1

Which of the following statements best describes the principle of complementarity in cell theory?

Accepted Answer

The biochemical activities of cells are dictated by their structure, which determines their function.

Question 2

A patient receives an intravenous solution that is hypotonic relative to their blood plasma. What is the most likely effect on their red blood cells?

Accepted Answer

Cells will swell and may burst as water enters them.

Question 3

Which organelle is primarily responsible for detoxifying harmful substances such as alcohol and formaldehyde in liver cells?

Accepted Answer

Peroxisomes

Question 4

During mitosis, which stage is characterized by the alignment of chromosomes along the center of the cell?

Accepted Answer

Metaphase

Question 5

Which of the following best describes the chemical composition of the plasma membrane?

Accepted Answer

Two layers of phospholipids arranged tail-to-tail, with cholesterol and proteins scattered among them.

Question 6

A cell is placed in a hypertonic solution. Which direction will water move, and what is the likely outcome for the cell?

Accepted Answer

Water will move out of the cell, causing it to shrink.

Question 7

Which transport process requires ATP and moves substances against their concentration gradient?

Accepted Answer

Active transport

Question 8

Which tissue type is characterized by its ability to regenerate easily if well nourished, is avascular, and forms sheets with an apical surface?

Accepted Answer

Epithelial tissue

Question 9

Which of the following is a function of the Golgi apparatus in a cell?

Accepted Answer

Modifying and packaging proteins for secretion or use within the cell

Question 10

Which equation best represents the movement of water during osmosis across a semipermeable membrane?

Accepted Answer

$$ J_{water} = A \cdot (\pi_{outside} - \pi_{inside}) $$

Question 11

Which cell junction allows ions and small molecules to pass directly from one cell to another, facilitating rapid communication?

Accepted Answer

Gap junctions

Question 12

A mutation prevents the formation of ribosomes in a cell. Which process would be most directly affected?

Accepted Answer

Question 13

Which tissue type forms the internal framework (stroma) of organs such as lymph nodes, spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 14

Which of the following best describes the function of microvilli on epithelial cells lining the small intestine?

Accepted Answer

Increasing surface area for absorption

Question 15

Which equation describes the rate of simple diffusion across a membrane?

Accepted Answer

Question 16

Which of the following is NOT a function of epithelial tissue?

Accepted Answer

ATP production

Question 17

Which of the following best explains why the plasma membrane is selectively permeable?

Accepted Answer

Its hydrophobic interior prevents passage of most water-soluble molecules.

Question 18

Which tissue type is responsible for conducting electrochemical impulses and is composed of neurons and neuroglia?

Accepted Answer
