Explain how much the post-hurricane birds varied from the original birds after 1 million years of natural selection. How do adaptations and natural selection explain the changes?

Giraffes with short necks tend to be unable to access enough food, while giraffes with long necks can reach more food at the tops of trees. this causes an advantage for giraffes with long necks. how would you explain this? a. this is an example of a stabilizing selection in which the intermediate form of a trait is advantageous compared to the extreme forms of the trait. b. this is an example of a disruptive selection in which the population of cacti is divided and well-defined. c. this is an example of directional selection in which one end of the bell curve is better adapted to its environment than the other end. d. this is an example of bidirectional selection in which evolutionary pressures from multiple sources encourage an organism to adapt

Water moving sediment down slopes and a glacier forming a u-shaped valley as it moves past mountains are examples of

An air mass's relative humidity is a measure of how much water vapor it contains compared to how much it can contain. different types of air masses, with different temperatures and pressures, are able to hold different amounts of water vapor. which of the following could cause the relative humidity of an air mass to change? a change in its temperature a change in its pressure a change in its water vapor content all of these
