A phylogenetic tree is a branching diagram showing evolutionary relationships among various living organisms based upon similarities and differences in their physical or genetic characteristics like the one above. In this case a human is more closely related to a mouse than a kangaroo, A platypus is more closely related to a kangaroo than a mouse, a human and a kangaroo share common features because of a common ancestor.
Answer: Parents with normal skin colour will have an albino baby if both of them are heterozygous for the trait.
Explanation: A parent who is heterozygous will have one dominant allele (A) for normal skin colour and one recessive allele (a) for albinism. If both of them are heterozygous for the trait, there is possibility of them producing an albino baby.
_ A a
A AA Aa
a Aa aa
The cross produces one homozygous normal skin coloured baby (AA), two heterozygous normal skin coloured babies (Aa)- and one albino baby (aa).

The purpose of container B in the experiment is that it serve control container because it is in the comparison with the container A.
<h3>Is seed give off oxygen?</h3>
No, seed does not give off oxygen because seeds need oxygen in order to produce energy for germination and growth. The embryo gets energy by breaking down its food that is stored in the seed. This is done through a process known as aerobic respiration.
So we can conclude that The purpose of container B in the experiment is that it serve control container because it is in the comparison with the container A.
