The diffusion of substances within a solution tends to move those substances their gradient

A. up; electrical

B. up; electrochemical

C. down; pressure

D. down; concentration

Answer Explanation:

In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.

Therefore, the Correct Answer is D.

Q #1: The diffusion of substances within a solution tends to move those substances ________ their ________ gradient

A. up; electrical

B. up; electrochemical

C. down; pressure

D. down; concentration

Answer Explanation

In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space.
Q #2: Ion pumps and phagocytosis are both examples of ________

A. endocytosis

B. passive transport

C. active transport

D. facilitated diffusion

Answer Explanation

Phagocytosis, pinocytosis, and exocytosis are all examples of active transport. Active transport is a type of transport that uses energy. During phagocytosis, cells use their membrane to take in large molecules from the external environment.
Q #3: In a hypertonic solution, water flows through aquaporins embedded in the plasma membrane of the cell. This type of transport is best known as which of the following?

A. Osmosis

B. Diffusion

C. Active transport

D. Facilitated diffusion

Answer Explanation

The movement of water from a region of high-water concentration to a region of low water concentration across a semipermeable is called osmosis. It is the diffusion of water that can occur in hypertonic solution, hypotonic solution and isotonic solution.
Q #4: Choose the answer that best completes the following analogy: Diffusion is to ________ as endocytosis is to ________

A. filtration; phagocytosis

B. osmosis; pinocytosis

C. solutes; fluid

D. gradient; chemical energy
