Question 2

Which of the following is NOT one of the four most common elements found in the human body?

Accepted Answer

Calcium

Question 3

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

Accepted Answer

The cells will swell and may burst due to water moving into the cells by osmosis.

Question 4

Which of the following best describes a polar molecule?

Accepted Answer

A molecule with an uneven distribution of charge, resulting in positive and negative poles.

Question 5

Which macromolecule is primarily responsible for storing genetic information?

Accepted Answer

DNA

Question 6

Which of the following best describes the process of translation in protein synthesis?

Accepted Answer

The process by which the sequence of bases in mRNA is used to assemble amino acids into a polypeptide chain.

Question 7

Which of the following is a function of epithelial tissue?

Accepted Answer

Covering body surfaces and lining body cavities.

Question 8

A cell is placed in a solution and water moves out of the cell, causing it to shrink. What type of solution is the cell in?

Accepted Answer

Hypertonic

Question 9

Which of the following best describes the difference between passive and active transport across the plasma membrane?

Accepted Answer

Passive transport does not require energy, while active transport requires ATP.

Question 10

Which of the following is a correct sequence of events in the flow of genetic information in a cell?

Accepted Answer

DNA is transcribed into mRNA, which is then translated into protein.

Question 11

Which of the following best explains why water is considered a polar molecule?

Accepted Answer

The oxygen atom is more electronegative than the hydrogen atoms, creating a partial negative charge near the oxygen and a partial positive charge near the hydrogens.

Question 12

A patient is unable to digest fats properly due to a deficiency in a certain macromolecule. Which macromolecule is most likely deficient?

Accepted Answer

Enzymes (proteins)

Question 13

Which of the following is a characteristic of connective tissue?

Accepted Answer

It contains cells separated by an abundant extracellular matrix.

Question 14

Which of the following best describes the function of ribosomes in a cell?

Accepted Answer

They are the site of protein synthesis.

Question 15

A scientist is studying a tissue that is avascular, has tightly packed cells, and lines the inside of the stomach. Which tissue type is being studied?

Accepted Answer

Epithelial tissue

Question 16

Which of the following equations correctly represents the hydrolysis of ATP?

Accepted Answer

Question 17

A mutation in the gene coding for a membrane protein prevents glucose from entering the cell. Which transport process is most likely affected?

Accepted Answer

Facilitated diffusion

Question 18

Which of the following best describes the role of phospholipids in the plasma membrane?

Accepted Answer

They form a bilayer that acts as a barrier to most water-soluble substances.

Question 19

Which of the following statements about nervous tissue is correct?

Accepted Answer

It is specialized for the conduction of electrical impulses.

Question 20
