Mountains generally have very cold temperatures at the peak, right? Cold air has trouble holding precipitation and turns into snow. Why is there greater precipitation in the mountain than in the plains?

I'm a student in a General Biology course and I'm looking for some good, free, online biology quizzes (right now, with regards to evolution and whatnot).

Thanks in advance.

Unlikely yes, but is it possible? I'm not talking about clones or with any type of human interference.

In the Bio Lab class, teacher gave us a lot of different types of cells in one plate to look in the microscope, so everyone had to look and identify which one is which, what is the name of the cell they found.

I was the only one who didn't find any cell in my plate. The whole class found 3 cells and we needed to find 4 cells and identify them. I didn't know how to use the microscope. I went to the tutoring lab but that didn't help me at all.

Tomorrow, I have the lab class again, I feel so stupid and very nervous.
