Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Answer:
compound can be broken down into smaller compound or their basic element by chemical change
<span>The answer to this question would be: hypertonic, hypotonic
After eating, the intestine is filled with food that will be digested. Food that digested will turn into a much smaller unit of carbohydrate, amino acid and fatty acid that will cause the intestine to have hypertonic solution compared to the blood. This will induce diffusion of some molecule to the intestinal cell, and then to the blood.</span>
Answer:
Wind

Small
White of light colors
Produces a lot of pollen
