Answer 1

Birdsong structures can vary in size between male and female birds, influenced by genetics and hormones.

Step-by-step explanation:

The correct answer is D) All of the answers are correct.

Birdsong structures can vary in size between male and female birds, but it depends on the species. In some species, male birds may have larger songs to attract mates, while in others, male and female songs may be similar in size. This variation is influenced by genetics and hormones.

For example, in species where males use courtship rituals or colorful plumage to attract mates, the songs may play a role in assisting with parental care. The songs can communicate to females their ability to provide care and support.
