Question

As a result of diffusion,the concentration of many types of substance a.) always remains greater inside a membrane. b.)eventually becomes balanced on both side of a membrane. c.)always remains greater on the outside of a membrane. d.)becomes imbalanced on both sides of a membrane.

Answer 1

As a result of diffusion the concentration of many types of substance eventually become balanced on both sides of the membrane.

b.)eventually becomes balanced on both side of a membrane.

Explanation:

Diffusion is the process by which substances move from a region of high concentration to low concentration. It is crucial in several biological processes and is a form of passive transport. Since the movement is down the concentration gradient,  passive transport doesn’t require any energy.

When there exists a difference in concentration between the substances inside and outside a membrane the diffusion of substances through the membrane begins. The diffusion continues until the concentration of substances inside and outside of the membrane becomes balanced.
