Answer:
See explanation
Explanation:
We inherit our blood groups from both parents. Our blood type is controlled by a single gene. This gene displays 3 different allelic pairs which must include A, B or O.  A child is expected to receive one of the three possible allelic pairs from each of the both parents. This means that there are six possible genotype and four possible phenotype for the child. 
Given that Christopher's parents (Andersons) are AB and O,Christopher can have a B blood group.
Given that John's parents (Browns) are A and O, it explains how John can have blood group A.
Given that The Christiansons are A and AB, they can give birth to Robin whose blood group is AB.
Since the Dietrichs are O and O, the only possible blood group of their child is O, hence they are definitely the parents of Jane.
 
        
             
        
        
        
Answer:
The correct answer is carbon.
Explanation:
Carbon is the major constituent of almost all organic compound.Carbon in form of carbon dioxide is used during photosynthesis in which the CO2 act as reactant that interact with water to generate glucose and oxygen.
       On the other hand carbon is found in carbohydrates such as glucose contain 6 carbon atoms,found in protein which contain a carboxy terminal end and an amino terminal end,found in the fatty acid monomers of lipid molecules.

Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
