None of the molecules can be absorbed because they can’t cross the cell membrane without help. There aren’t transporters to carry them across
Damm [24]2 years ago

Explanation:

Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across

Predict how changing the grass population will affect the other organisms at first. Write + for “Increase” or – “Decrease” next
Afina-wow [57]

Answer: Here you go!

Explanation:

Doubling the amount of grass would definitely increase the rabbit population since there is more food/resources for it to produce. Since the food chain has a domino effect everything else would go up as well because of the increase of food/resources that will help sustain the population of all. so for the first line it would be increase for rabbit snake and hawk. Halving the amount of grass would effect the population of all animals as well. But in a more negative way. It would decrease because the rabbits wouldn't have enough food to produce and thrive. With the decline of rabbits less snakes will live because of the low amount of their main food source. Same with the eagles. So therefore it would be decrease in all the bottom lines.
