B, the independent variable because this is the one that is purposefully changed in an experiment to test the hypothesis.
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.
Answer:
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.
