Answer:
D. Phosphate group
Explanation:
When oxygen is added to a carbon chain, one of the predicted outcomes is the addition of a phosphate group to ADP, which generates ATP. Furthermore, during cellular respiration, biological energy is converted to generate adenosine triphosphate, which is used by the cells for energy.
Answer is Homologous.
A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.
Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.
For the first 12 hours after conception, the fertilized egg remains a single cell. ... During the first 8 or 9 days after conception, the cells that will eventually form the embryo continue to divide

Thats a hypothesis another word for it is a theory but the scientific term is a hypothesis, hope this helps love
