Question

In passive absorption, nutrients enter the cell

Select one:

a. with a carrier.

b. with the expenditure of energy.

c. from an area of higher solute concentration to one of lower concentration.

d. from an area of lower solute concentration to one of higher concentration.

Answer 1

In passive absorption, nutrients enter the cell through passive transport, moving from an area of higher solute concentration to one of lower concentration, without the need for energy.

Step-by-step explanation:

In passive absorption, nutrients enter the cell from an area of higher solute concentration to one of lower concentration. This process does not require energy because it's a naturally occurring phenomenon called diffusion. The movement of substances occurs along the concentration gradient until equilibrium is reached. Therefore, substances move freely through the plasma membrane, and this process is categorized as a form of passive transport. Additionally, solutions in biology are characterized by the solute; hence the movement is from a place where the solute is more concentrated to where it is less concentrated.

Answer 2

c. from an area of higher solute concentration to one of lower concentration.

Step-by-step explanation:

Passive absorption is a process in which the molecules or ions moves from the region of its higher concentration to its lower concentration or along the concentration gradient. The passive absorption takes place along the concentration gradient, hence no energy is needed for the movement of molecules across the membrane. Simple diffusion or facilitated diffusion is an example of passive absorption.
