Read the paragraph and answer the Question given below:

Humans are sexually reproducing and viviparous. The male reproductive system is composed of a pair of testes the male sex accessory ducts and the accessory glands and external genitalia. The female reproductive system consists of a pair of ovaries a pair of oviducts, a uterus, a vagina, external genitalia and pair of mammary glands. The reproductive cycle of female primates is called menstrual cycle. Menstrual cycle starts only after attaining sexual maturation (puberty). Coitus followed by fertilization leads to formation of zygote. After 9 months of pregnancy, the fully developed foetus is ready for delivery.

The nucleus is present in _______ of human sperm.

Head

The correct answer is Option (3) → Head

The nucleus of a human sperm is located in its head, where it houses the genetic material (DNA). The head is covered by the acrosome, a cap-like structure that contains enzymes to help the sperm penetrate the egg during fertilization.

The other parts of the sperm have different functions:

• Middle piece: Contains mitochondria, which provide energy for the sperm's movement.
• Tail: Facilitates the motility of the sperm, allowing it to swim toward the egg.
• Acrosome: Contains enzymes, but no nucleus.
