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.

Which of the following statements is true?
julia-pushkina [17]

Answer: Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.

Explanation:

A germline mutation is the mutation in the germ cells (of the fully developed sperm and ovum) of the parents. When the affected parents undergoes with the sexual reproduction the mutations are passed from the parents to the offsprings. When either the mutated oocyte or mutated sperm meet to form a zygote the precursor of new life. Thus few mutations are inherited by sexual reproduction than by asexual reproduction.
