Answer:
C. 100 percent
Explanation:
The woman is heterozygote: AO, while the man is homozygote: BB
By crossing the two:
AO x BB
A+B, A+B, O+B, O+B
AB, AB, OB, OB
We have two AB and two OB offspring. Both AB and OB are heterozygotes.
Thus all their offspring will be heterozygous.
<em>Had the question asked what proportion will be OB, the answer would have been 50%.</em>
Since the question asked, what proportion will be heterozygotes and not about the specific genotype, the correct answer is C. 100 percent
Answer:
Chemical energy that is stored in the food molecules such as sugars are converted into the chemical energy that is available for the cell to perform various cellular functions, it is stored in ATP known as the currency of the cell.
ATP has three phosphate groups attached to adenosine by a phosphoanhydride bond. When a cell requires energy it loses the third phosphate group and releases a huge amount of energy stored in the phosphoanhydride group and form ADP.
When the second phosphate group is lost by breaking the bond again energy is released again left AMP. The breaking of this bond takes place due to hydrolysis reaction
Evolution and natural selection are for C. The long term survival of an entire species of organisms. Organisms are better suited to live in a particular environment due to the transmission of specific genes from the parental generation to the offspring that can lead to these species evolving if much mutations are associated also with the passing down of specific alleles for respective genes that enable the organism to survive for a longer duration in its environment.
Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
