Review fertilization of life cycle. The somatic cells of human bodies are O diploid (2N) O haploid (N)

O Sertoli cells-progesterone O hypothalamus-FSH Question 4 Which of the following is a similarity between spermatogenesis and oogenesis in vertebrate animals? Both spermatogenesis and oogenesis__ O result in the production of four functional haploid cells from one diploid cell O begin at the onset of sexual maturity O lead to the production of gametes from germ cells O generate diploid gametes via meiotic divisions Question 5 Where are human sperm produced? O vas deferens O prostate gland O epididymis

Describe the human life cycle and indicate where in the human body that mitosis and meiosis occur and which cells are the result of meiosis and mitosis. Show which cells are diploid and haploid.

meiosis is the process where organisms producé 81isping called9ametes Cells are a combination of reproductive cells, ova and spermatozoa that are produced by a unique process of cell division called. Except for it is virtually impossible for two animals to or have exactly the same genetic makeup. The genetic material in the body's cells is contained in the in the form of coiled masses of DNA called are the male reproductive cells are formed. The These are the organs where the male Testes are generally in shape and their varies among species. The testes develop near the in the portion of the abdomen. The testes are attached to their permanent home in the scrotum, by a band of connective tissue called the is the process by which the seminiferous tubules of the testes produce sperm. The inability of the penis to retract into the prepuce Is called The structure that protects the penis in animals is the link the testes with the rest of the body. They are tube-like, that contain blood…
