Question

Skeletal muscle cells have many, and mature red blood cells have none at all; but nearly all other cells of the body have a single _____.

A) Nucleus
B) Mitochondrion
C) Golgi apparatus
D) Ribosome

Answer 1

Skeletal muscle cells have multiple nuclei, mature red blood cells lack a nucleus, and nearly all other cells in the body have a single nucleus; hence the answer is A) Nucleus.

Step-by-step explanation:

Skeletal muscle cells are unique in that they have many nuclei, while mature red blood cells have none at all. In stark contrast to these two cell types, nearly all other cells within the body contain a single nucleus. The nucleus is considered the control center of the cell because it houses all genetic instructions for protein manufacturing. Keeping these characteristics in mind, the correct answer to the given question is A) Nucleus.
