Answer 8

If mutation caused there to be some humans that could fly, what might happen?

It might take thousands or millions of years, but the ability to fly might increase in the population, since it would probably be adaptive.

Nicole and Tony's parents were concert pianists. Nicole practiced for 2 hours a day since she was 3, and she became a famous pianist herself. Tony was not interested in piano, and was not that good, but found he could pick up tunes fairly easily at a party if there was a piano around. What does this scenario demonstrate?

The piano-playing was inherited.

The piano-playing was acquired.

The talent to play was likely inherited, but actual proficiency (becoming good) was an acquired trait.

Nothing can be determined from this scenario.

Warning calls are acquired; songs are inherited

Songs are acquired; warning calls are inherited
