Compare passive and active transport through the cell membrane, including energy use and concentration gradients.

Passive transport vs active transport sounds like what it is. In passive transport, there is no energy needed to get the molecules across the cell membrane, whereas in active transport, energy is expended getting the molecules across the membrane. Basically in active transport the ATP in your cells gives one of it’s phosphates to the transport proteins in your cell membrane and it lets select molecules in. These molecules are moving through a concentration gradient during active transport(with the help of ATP), from an area of low concentration to an area of high concentration.

The nurse should include dirahea, dry mouth, vomiting, decreased sex drive, lack of coordination, tingly feelings, impotence, or difficulty having an orgasm.. good luck

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
