Hi!
Question - How do mutations lead to variation
Answer - B. By producing changes in the genetic code
Why - "In which can create entirely new alleles in a population"
it uses this energy to survive and to hunt for more energy
C) Natural selection
When something happens in nature and something changes all of a sudden, the animals tend to adapt to what gives them more chances of survival. As a result, a large amount of the population would attempt to adapt in a way that helps them survive.
I think it is A to, since the tissues are the closet thing to cell, which microscopic anatomy studies.
Ah, I'm not sure. I hope someone helps you!
