If the cilia of a paramecium were destroyed, the most direct effect would be on the ability of the paramecium to A. Release energy
B. Produce offspring
C. Obtain food
D. Excrete solid wastes

C.obtain food

Explanation:

A paramecium is a unicellular organism

If the cilia of a paramecium were destroyed, the most direct effect would on the ability of the paramecium to obtain food.

Without the cilia in this organism, the ability to obtain food would be totally and completely lost.

After the food falls into the oral groove of the paramecium, the cilia sweeps in the water and the food inside.

This food is passed from the oral groove into the gullet.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
