eir skin and an outer layer of longer hair that keeps them dry underwater. Which of the following describes how otters developed this type of fur coat? The otters adapted gradually over many generations.

The answer is language. Humans have a high degree of language acquisition and complexity compared to
chimpanzees due to foxp2 proteins. Foxp2
are transcription factors that are significant in cell proliferation. The difference of 2 in 700 amino acids in the sequence makes the protein to be differentially regulated between the two
species.
Compare and contrast inexhaustible and renewable resources. Inexhaustible resources are sources of energy that will never run out. In contrast, renewable resources could potentially run out. They are finite energy resources that can be replaced in a relatively short period of time.
