Explanation:
The nervous system is the part of an animal's body that coordinates its behavior and transmits signals between different body areas.
Facilitated diffusion and active transport
<span>Facilitated diffusion is the movement of large particles (that cannot otherwise move across the cell membrane) from an area of higher concentration to an area of lower concentration with the help of trans-membrane proteins.</span>
<span>Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration using ATP energy. this may occur with large particles that cannot move across the cell membrane or small ones that can but don't due to the concentration gradient.</span>
Both essential and nonessential hormones
Answer:
Most tissues of the body grow by increasing their cell number, but this growth ... photography of a live plant cell nucleus undergoing mitosis.
Answer:
[ANSWER]
Explanation:
When a molecule moves down its concentration gradient is it participating in passive transport; moving up the concentration gradient requires energy making it active transport.
