Pheasants do not feed their chicks. immediately after hatching, a pheasant chick starts pecking at seeds and insects on the ground. based on your understanding of animal behavior, what is a reasonable explanation for these observations? a. pecking is an example of associative learning. b. pecking is the result of imprinting during a critical period. c. pheasants learned to peck, and their offspring inherited this behavior. d. pheasants that pecked immediately after hatching had the highest survival and reproductive success

D. Pheasants that pecked immediately after hatching had the highest survival and reproductive success

Explanation:

This means that behavior of pecking increased their survival and reproductive success and become favorable by natural selection.

Natural selection is evolutionary mechanism which favours traits (structures, behavior) of an organism that help him survive and reproduce. In the example, above, pheasants that pecked survived and that was the favorable trait by natural selection.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
