안녕하세요

선생님 강의 보고 공부하면서 문제집 풀다가 잘 모르겠는 문제들이 있어서 또 질문 드립니다.

1) Which of the following is an assumption underlying natural selection?

A) Random mutations increase genetic variation

B) Organisms do not migrate to different environments

C) Organisms are continually trying to adapt

저는 A 가 맞는 답이라고 생각했는데 답지는 C가 맞는 답안이라고 나와요.. C 는 Lamarck의 틀린 theory 아니였나요..?

2) which of the following experimental procedures would best demonstrate whether bile from the gallbladder of a mouse is released in response to a nerve impulse?

A) Cutting the motor nerves to the gallbladder

B) Cutting the sensory nerves from the gallbladder

저는 B 라고 생각했는데 답지에는 A라고 나와서 했갈리네요..

다시한번 감사드립니다..
