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.
because it is a new virus that us humans have not experienced and we are still learning about it
The answer is Habitat. The brackish water environment is formed due to the mixing of fresh water from the river with the salty waters of the ocean. This habitat is significant for fishes that come to spawn and feed. Crabs, mosquitoes and birds can also be found in this environment.
The answer is skin cells. Other cells, like nerve and brain cells, divide much less often.
Alcohol is a solvent and it basically dissolves anything. A lead is spongy and full of holes. When the leaf is mixed with alcohol, the alcohol affects the leaves. The alcohol melts the pigments of the leaf, chlorophyll, which is the green part. This will turn the alcohol green
