Question 1

Which of the following best describes the process of osmosis in human cells?

Accepted Answer

The movement of water molecules from an area of low solute concentration to high solute concentration across a semipermeable membrane.

Question 2

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

Accepted Answer

It will swell and possibly burst because water will move into the cell.

Question 3

Which of the following is the correct formula for calculating the rate of diffusion?

Accepted Answer

$$Rate = \frac{Distance}{Time}$$

A scientist wants to measure the amount of solute dissolved in 1 liter of solution. Which unit would be most appropriate?

Accepted Answer

Milligrams per liter (mg/L)

Question 6

Which of the following best describes facilitated diffusion?

Movement of molecules down their concentration gradient with the help of membrane proteins.

Question 7

If a solution contains 0.9% NaCl, what type of solution is it relative to human red blood cells?

Accepted Answer

Isotonic

Question 8

Which of the following is the correct conversion from milligrams to grams?

Accepted Answer

Question 9

A patient is given intravenous fluids that are hypertonic compared to their blood plasma. What is the most likely effect on their red blood cells?

Accepted Answer

Cells will shrink due to water efflux.

Question 10

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

Accepted Answer

It regulates the movement of substances into and out of the cell.

Question 11

Accepted Answer

$$10 \ g/L$$

Question 16

Which of the following best describes the process of filtration in the kidneys?

Accepted Answer

Question 17

Which of the following is the correct conversion from meters to centimeters?

Accepted Answer

$$1 	ext{ meter} = 100 	ext{ centimeters}$$

Question 18

Which of the following best describes the anatomical position?
