Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If something goes “along” its concentration gradient it goes from
A
an area of low concentration to an area of high concentration
B
an area of high concentration to an area of low concetration
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.

Detailed explanation-2: -In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.

Detailed explanation-3: -Active transport is a kind of cellular transport where substances move against a concentration gradient. This means that the direction is from an area of lower concentration to an area of higher concentration.
