Explanation:
D. The shape of an enzyme is determined by its Nucleic acid sequence.
The answer is D. Natural selection favors the organisms best fit for their environment. These are organisms that can best survive in a given situation. Natural selection occurs when organisms have different characteristics, and vary genetically. This is logical because some organisms die, while others live, during a trying event. This leaves room for evolution. The “weak” trees would die off, leaving behind the stronger trees, which reproduce and create strong trees. Eventually all the weak trees die off, and the strong, drought-resistant trees remain.
According to the behaviorist perspective, an organism learns the association between two stimuli because they are paired together, not because the organism knows that one stimulus will follow another and this is true because behaviorist relate to the study of human/animal behavior to learn.
