Conversion of spermatids to spermatozoa involves cell division.
a. true
b. false

The correct answer will be option-False.

Explanation:

Spermatogenesis or formation of sperm cells in humans takes place in two stages: cellular division called "spermatocytogenesis" and metamorphic changes in spermatids to spermatozoa called "Spermiogenesis".

The mitotic and meiotic cellular division produces round spermatids which undergo much physical change during the process called Spermiogenesis.  During Spermiogenesis spermatids modify themselves for fertilization like acrosome cap formation, tail development and nuclear condensation.

Thus, option-false is the correct answer.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
