A CELL WALL because the other three appear in different types of cells
<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>
No, that is completely impossible. The reasoning behind it is because if its a large group of fish they're swimming back and forth ect, ect, it would be like counting a bowl of rice, but not being able to take any out. To get around these counting problems, scientists take data from just a small portion of the population called a sample. They take several samples and then use the average size of those samples to calculate an estimate of the entire population size.
