<span>In a dichotomous key you named them by their traits while in a branching diagram it already has the name and it's traits.

<span>Sam, a mendalien with black eyes and green skin, has a parent with orange eyes and white skin. Sam has a dominant phenotype expressed but he has a parent with a recessive phenotype which means he has a heterozygote gene.
Carole is a mendalien with orange eyes and white skin. Since Carole express both recessive phenotypes she should be homozygote recessive.
The key to this problem is how Sam dominant gene will be inherited. Since there are two heterozygote genes, it will be 50% dominant gene inherited for each phenotype. Then the result should be:
25% Dominant + Dominant =</span>black eyes and green skin<span>
25% Dominant + Recessive =</span>black eyes and white skin
25% Recessive + Dominant =orange eyes and green skin
25% Recessive + Recessive =orange eyes and white skin
They will actually explode or burst
So What happens is the pure water outside has a high water potential while the cytoplasm inside the animal cell is a low water potential, water will diffuse down a water potential gradient through the semi-permeable membrane of the animal cell and cause the cell to swell (inflate like a fully-blown balloon), the result is that the delicate, elastic cell membrane<span> can't tolerate the internal pressure coming from the cytoplasm so it tears causing the cell to burst.</span><span>

Hydrogen is the right answer
