Question

Which motion of particles across a membrane requires energy?
from high concentration to low concentration
from low concentration to high concentration
with no concentration gradient
through dynamic equilibrium

Answer 1

Answer:

1)active transport

Explanation:

2)This spread of particles through random motion from an area of high concentration to an area of lower concentration is known as diffusion. This unequal distribution of molecules is called a concentration gradient. Once the molecules become uniformly distributed, dynamic equilibrium exists.

Answer 2

Answer:

In active Transport Motion..
