Answer 1

The first ones all have * by the right answers. For the last one, the best answer is (b).

Answer 2

Obviously you are interested in the sciences since three of the four choices you have given are science related. Psychology woud be good if you enjoy helping others. There will be some classes in biology but nothing like if you were majoring in Biology. You also have an interest in criminology-There are so many roles in criminology-would you be interested in law enforcement, CSI (statistics show that the majority of high school seniors are choosing CSI), court advocacy, what? A degree in Biology and Engineering would be harder.

Answer 3

The first three are correct with * by them. The fourth is incorrect: bacteria reproduce by mitosis, which involves splitting into separate individual (but not necessarily identical) cells. The answer to the fifth is b.

Answer 4

I disagree with hcbiochem and N E on these answers.

Specifically, where are you having trouble? Simply handing over the answers would be cheating.
