Savanna do not exist in the united states because there are no true tropic climates.
Nerve cells because skin cells keep dividing when you loose skin. Epithelial cells also divide when you loose others.
Answer:
Water will move in and out of the cell equally
My guess:
I do not know the options to the blanks, but I'd say that the answer to the first one is "strongly linked". Think of a chromosome as a phylogenic chart → 2 species that are beside each other are strongly linked, if compared to 2 species 3 spots apart form each other. So, 2 genes that are close to each other are strongly linked.
I do not know the options to the blanks, but I'd say the answer to the second one is epistasis → which is the interaction between two different genes (different means they're not linked alleles).
Hope it helped,
