Adaptations are what organisms do in order for them to survive and adapt to the environments that Mother Nature is presenting them.
1. Crocodiles - have tough and scaled skin that allows them to camouflage and catch prey in the water
2. Frogs - have developed bodily fluids that secrete poison to prevent predators from attacking them
3. Bats - have developed their echolocation to help them in hunting for food at night time.
4. Coelachants - have maintained their extra fins for sensory motor in the water
5. Lampreys - have maintained their tooth-funnel like mouths in order to feed on their hosts.

The corpus callosum is a broad band of white matter. It connects both left and right cerebral hemispheres to allow communication. Also, it allows relaying of information to both hemispheres in order for the brain to function in a healthy way.
Answer:
C. But be careful. This question is poorly conceived. Anything could be the answer.
Explanation:
A B and D are all specific to the disciple they are involved in.
That only lets you choose C. You could argue that a physicist or an electrical engineer would not be particularly interested in the death of some elm trees, and I think I would agree with you.
But what other choice to you have?
While the professor is tracking the fresh water fish, how is that benefiting mankind? What is he learning that is universally applicable. I wouldn't choose A.
B is an advance in technology. It might make the dairy farmer's life a whole lot easier, but I don't think it would have very effect on anyone else. Not B.
D: Again this benefits surgeons but again it is technology. I don't think it universally benefits all of humanity except those who are going to be operated on.
So I'll stick with C. People die. So do trees and all vegetation. I'd pick C, but I don't think there is a clear cut answer. Sometimes you get questions that you think the answer resides only in the head of the person writing the question. This is one of them.
Cross-pollination, or when pollen from one plant fertilizes another plant of the same produces outcrossing or outbreeding.
Explanation:
Cross pollination is the transfer of pollen from a plant's stamen to a different plant's stigma of the same species. They produces stronger plants. For example only pollen from a daisy can pollinate another daisy.
They have male and female reproductive units on separate plant. If they are on the same plant he pollen will not fertilize the female reproductive unit on the plant.
This process needs four steps pollination, germination, penetration of the ovule and fertilization. The Zygote divides to form an embryo after fertilization.
