Movement of a molecule against its concentration gradient can occur through select one or more: a. facilitated diffusion b. passive transport c. osmosis d. simple diffusion e. active transport

The answer to your question is:

Explanation:

There are two kinds of cell transport passive transportation and active transportation.

Passive transportation does not need energy because molecules move from higher concentration to lower concentration.

Active transportation needs energy because molecules moves against concentration.  

a. facilitated diffusion It's an example of passive transportation so this answer is wrong.

b. passive transport Molecules move in favor of concentration so this answer is wrong.

c. osmosis is another example of passive transport so this answer is wrong.

d. simple diffusion it's another example of passive transport, so it's wrong this answer.

e. active transport this is the right answer.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

the right answer is 0.3 meters per second
