What type of cell transport uses carrier proteins? a. passive diffusion b. osmosis c. active transport d. facilitated diffusion

C. Active transport

Explanation:

Active transport refers to the movement of molecules and ions from their region of low concentration to their region of high concentration, across a membrane, against a concentration gradient. Active transport requires cellular energy and thus carrier proteins

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
