Evolutionary adaptation: a. refers both to the process by which populations become better matched to their environment and to the features of an organism that make it more fit than other individuals. b. cannot occur in environments influenced by humans. c. is possible only when there is no mutation. d. is responsible for the fact that porcupines are at an unusually high risk of predation. e. occurs for physical traits but not behaviors.

a.

During evoluionary adaption, animals become fit to their environment meaning they adapt to live in certain weather conditions, they evolve characteristics to defend them from their predators, they figure ways of creating houses, etc.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
