In many insect species, females possess a spermatheca. Based on the information provided, what is the most significant functional advantage of having a spermatheca?

  • A: It allows the female to attract males from a greater distance using pheromones.
  • B: It enables the female to store sperm, potentially fertilizing multiple batches of eggs from a single mating event.
  • C: It facilitates external fertilization by temporarily holding eggs before release.
  • D: It produces the fluid necessary for sperm motility within the female reproductive tract.

Explanation

The text states: 'An internal structure in the female called the spermatheca stores the sperm, usually enough to fertilize more than one batch of eggs. Many insects mate only once in a lifetime.' This directly indicates that the spermatheca allows for the fertilization of multiple egg batches from a single mating.
