• They require two parents to combine genetic material.

• They are always female.

What primary advantage does sexual reproduction offer to a species, especially in a changing environment?

• It allows for faster population growth.

• It produces genetically identical offspring.

• It increases genetic variation within the population.

• It requires less energy than asexual reproduction.

What event directly leads to menstruation if fertilization and implantation do not occur?

• A surge in Luteinizing Hormone (LH)

• The thickening of the uterine lining

• The shedding of the uterine lining
