Answer:
The correct answer is - osmosis.
Explanation:
Paramecium lives in freshwater like the Potomac River which is hypotonic to the cytosol of the paramecium. Paramecium uses contractile vacuoles to transport the water from the lower concentration (outside of the cell) to a high concentration of solvent to the inside of the cells.
This process of cell transport is carried out by osmosis as their cytoplasm contains a higher concentration of solutes outside the cell. This excess water is collected into vacuoles called contractile vacuole that swells and finally internalized the water to the outside of the cell.
Thus, the correct answer is - osmosis.
DNA helicase untwists the helix at the replication origins. Then the DNA is seperated into a "Y" shape called the replication fork.
