An organism is d. a group of organ systems working together.

An atom goes into a molecule which goes into a cell which goes into a tissue which goes into an organ which goes into an organ system which goes into an organism. 

Organs working together with other organs create a system of organs or an organ system. Something like this helps keep a human body, for example, functioning since everything relies on each other. 

Remember that if your respiratory (breathing) system and nervous (brain) system did not work together, you would not be alive, and therefore no longer a living organism.

which of the following statements are true regarding active transport and facilitated diffusion (choose two answers) a) Active t
Vera_Pavlovna [14]

Answer: B and D

Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.

Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.

This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.

Hope this helped.
