The answer to this question would be: oxygen
The presence of oxygen allows the cell to do the aerobic reaction. Using in metabolism will result in a much higher number of ATP produced.
When there is no oxygen, the cells make energy using the anaerobic reaction that gives a low number of ATP.
Answer:
characterized by presence or absence of antigens
the blood types are A, B, O, AB
Explanation:
There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.
Blood group Antigen present on RBC Antibodies in serum Genotype(s)
A antigen A anti-B AA or AO
B antigen B anti-A BB or BO
AB both A and B antigen none AB
O none anti-A and anti-B OO

<h3><u>Answer and explanation;</u></h3>
<u>Binary Fission. </u>
- <em><u>Binary division is a process of cell division in which an organism replicates itself together with its DNA, then divides into two identical organisms.</u></em>
- <em><u>Binary fusion is a type of asexual reproduction by separation of the body of n organism into two bodies</u></em>. Organism duplicates its genetic material also known as the DNA, and then divides into two parts, with each new organism receiving a copy of DNA.
Answer:
He is either not carrying the gene for RP or the RP gene has mutated.
Explanation:
RP or Retina Pigmentosa is an eye defect inherited by a person from a parent. The disease is degenerative as the individual gradually loses his sight. It normally starts off as night-blindness and could go as bad as a total loss of sight.
The mutation of both the RPGR and RP2 genes which are responsible for the function and structure of light-reception in the eye accounts for most cases of Retina Pigmentosa disease.
