Answer 1

Answer:

Human reproduction is any form of sexual reproduction resulting in human fertilization. It typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm. These are specialized reproductive cells called gametes, created in a process called meiosis. While normal cells contains 46 chromosomes, 23 pairs, gamete cells only contain 23 chromosomes, and it is when these two cells merge into one zygote cell that genetic recombination occurs and the new zygote contains 23 chromosomes from each parent, giving them 23 pairs. A typical 9-month gestation period is followed by childbirth. The fertilization of the ovum may be achieved by artificial insemination methods, which do not involve sexual intercourse. Assisted reproductive technology also exists.

Answer 2

Human reproduction involves two individuals in order to produce a new individual to the world.

Explanation:

• The male reproductive organ releases sperms which pass into the vagina of the females which forms the female reproductive organ.
• Millions of sperms pass into the vagina and only one of them will join the sperm in the production of the egg which develops later to produce the baby in a mother’s womb and gets protected.
