Answer #1

The  Sign Stimulus also known as a releaser, is the determining feature of a stimulus that produces a response. It is an external sensory stimulus that triggers a fixed action pattern.A supernormal stimulus or superstimulus is an exaggerated version of a stimulus to which there is an existing response tendency, or any stimulus that elicits a response more strongly than the stimulus for which it evolved.A sign stimulus or released is a necessary characteristic within a stimulus which is a prerequisite for eliciting a behavioral response.

1. Describe situations or environments in which sexual selection is evolutionary advantageous. 2. In various reptiles, temperature determines sex during development. Some scientists suggest that as Earth's climate becomes warmer, sex ratios in these species will be biased and the animals will become even more endagered. Is this concern warranted and why? What might happen to these populations as a result?
