Please help me Important Ions move from low to high concentration while using a membrane protein. Which of the following is true? Question 5 options:

A. It's moving down the concentration gradient.

B. Energy is needed to make this happen

C. It's facilitated diffusion.

D. It's osmosis.

A) it is moving down the concentration gradient

Explanation:

Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
