Awoman with blue eyes (bb) and a man with brown eyes (bb) has a child. what is the percentage change that the child will have blue eyes?

The percentage chance that the child will have blue eyes is: 25%.

Explanation:

According to Mendel laws, there would be a 50% chance of having a child that is heterozygous for the gene (Bb) but happens to express brown eyes because this is the dominant allele;  there's 25% chance of having a child who  is homozygous for the dominant allele (BB) and will also have brown eyes; finally, there's a 25% chance of having a child who is homozygous for the recessive allele (bb) so their phenotype will be blue eyes.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
