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.

zvonat [6]
I believe the answer is Unicellular Euglena. 
Euglena are unicellular organisms classified into the kingdom protista, and the phylum euglenophyta. All euglena have chloroplast and can make their own food by photosynthesis. They are considered to have both plant and animal features. The mobility of Euglena also allows for hunting capability, because of this adaptation.
