Answer the following question given this paragraph: After spermatids form, they move into the epididymis to mature into sperm, like the one shown in Figure below . The spermatids grow a tail and lose excess cytoplasm from the head. When a sperm is mature, the tail can rotate like a propeller, so the sperm can propel itself forward. Mitochondria in the connecting piece produce the energy (ATP) needed for movement. The head of the mature sperm consists mainly of the nucleus, which carries copies of the father's chromosomes. The part of the head called the acrosome produces enzymes that help the sperm head penetrate an egg. Q: After spermatids form, they move where to mature into sperm? Choices: - into the prostate - into the volaris - into the vans deferens - into the epididymis A:
(A).
into the epididymis
