Answer 0

water moving through a selectively permeable membrane to reach equillibrium

Question 1

Diffusion

Answer 1

moving from an area of high concentration to low concentration to reach equillibrium

Question 2

Active Transport

Answer 2

process that moves material across a cell membrane against a concentration gradient using energy

Question 3

cellular respiration

Answer 3

process that releases energy by breaking down glucose etc. in the presence of oxygen

Question 4

facilitated diffusion

Answer 4

passive transport of molecules down a concentration gradient with the aid of special transport proteins

Question 5

passive transport

Answer 5

movement of molecules across the cell that doesnt require energy
