One function of the male reproductive system in mammals is to

• produce insulin necessary for sexual reproduction
• transport eggs necessary for fertilization
• allow for delivery of gametes needed for reproduction
• provide protection for the developing zygote

The diagrams below represent a human organ system. The major function of the system is to

• provide immunity essential for the survival of each individual in a population
• provide cells that are necessary for the survival of the species
• produce chemical messages that are necessary for nerve cell development
• control the passage of nutrients into and out of a developing fetus

The primary function of the human male reproductive system is to

• provide a site for fertilization
• produce and transport gametes
• protect and nourish the embryo
• prevent urine from leaving the body

The inability of sperm cells to move normally could prevent the production of offspring by interfering with

• meiosis
• fertilization
• mitosis
• differentiation

Which structure is correctly paired with its function?

• ovary — provides milk for newborns
• placenta — storage of released eggs
• uterus — produces estrogen
• testis — development of sperm

Testosterone directly affects the

• formation of a zygote
• changes within an ovary
• production of sperm cells
• development of a placenta

Which situation would be part of the normal reproductive cycle of a human?

• the presence of testosterone regulating gamete production in a male
• estrogen in concentrations that would produce sperm in a female
• a high progesterone level in a male
• a low insulin level in either a male or a female

The diagram below represents the human male reproductive system. Which activity would be prevented by blockages at X and Y?

• transport of urine out of the body
• passage of testosterone to the female to stimulate egg production
• movement of sperm out of the body
• movement of testosterone to the testes to stimulate sperm production

The diagram below represents a system in the human body. The primary function of structure X is to

• produce energy needed for sperm to move
• provide food for the sperm to carry to the egg
• produce and store urine
• form gametes that may be involved in fertilization
