Answer to Question 1

C
Feedback:
Sperm cells are highly specialized and are made up of several divisions. The body (middle piece) contains mitochondria, which provide the energy necessary for locomotion. The head contains 23 chromosomes (half of the human genetic material). The tip of the head, the acrosome, contains enzymes that can dissolve the tough cell wall of the ovum (the female sex cell). The whip-like tail is a flagellum that propels the sperm with a lashing motion.
