What is a key characteristic of the female gamete (ovum) in terms of its development?

• It is very small and quickly produced.

• It requires a long time to develop and a significant investment of resources.

• It is produced in vast numbers to increase chances of fertilization.

• It is simple in structure and easily expendable.

How do male gametes (sperm) typically achieve successful reproduction compared to female gametes?

• By being large and complex.

• By requiring a long development period.

• By being produced in very large quantities.

• By being protected inside the body.

Why are the testes located outside the main body cavity in males?

• To protect them from physical harm.

• To allow for easier release of sperm.

• To maintain a cooler temperature necessary for sperm production.

• To produce more hormones.

Which hormone directly stimulates Leydig cells in the testes to produce testosterone?

• Gonadotropin-releasing hormone (GnRH)
