Answer: Option B) Coelom
Explanation:
Hydrostatic skeleton is the type of skeleton possessed by soft-bodied animals such as earthworms and sea anemones. Fluid is secreted to fill the cavity spaces (coelom) in their body. The fluid then presses against the muscular body wall, causing the muscles to contract exerting pressure against the fluid thereby causing motion
Thus, coelom is the fluid cavity of the earthworm that gives it a hydrostatic skeleton
I think the answer is c) the preservatives slow the growth og mold and bacteria
Diffusion is when particles move from an area of high concentration to an area of low concentration. Think of it like a little kid party with two bouncy houses. Let's say that both bouncy houses have the same number of kids, but then half of the people in one bouncy house decide to go get lunch. Then one bouncy house is really full and the other almost empty! So you move to the empty bouncy house so you have more space to jump. This is diffusion. So it helps homeostasis because (back to the bouncy house example) you helped even out the two bouncy houses. Now let's say the kids come back from lunch. Now that bouncy house is too crowded so you move back to the now-emptier one. This is diffusion and you would be helping maintain homeostasis, or an equal level, in both bouncy houses.
This sums up most of them
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
