The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.
In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.
Answer: The answer is D. All of the above
Based on the seed experiment in the Poop Lab, the seeds that are expected to sprout are the seed in the elephant poop while the seeds in the soil are not expected to sprout.
<h3>What was the Poop Lab?</h3>
The main idea of the Poop Lab is to compare the growth of seeds that have gone through the digestive system of an animal, in this case, an elephant, to a seed that has not.
The seed that had gone through the digestive system was observed to have sprouted but the seeds in the soil did not. This experiment demonstrates the role animals such as elephants play in shaping the ecosystem through seed dispersal.
The seed that passed through the digestive system of the element and then passed out into the poop received enough nutrients for growth.
However, the seed in the soil does not receive adequate nutrients.

Answer:
galactose and glucose
Explanation:
Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose hope this worked :)
