Natural selection is the correct answer
Answer:
A) Humans without this gene exhibit problem with oxygen binding in their red blood cells.
Explanation:
- Oxygen binds to red blood cells because of their hemoglobin component. It is a protein found in red blood cells.
- Each hemoglobin molecule is able to bind to four oxygen molecules.
- If the gene controlling hemoglobin production is absent in humans, the red blood cells will not be able to bind to oxygen.
- Hence, if the gene given in diagram is removed and it results in difficulty in binding of oxygen to red blood cells, that gene might be involved in hemoglobin production.
The answer is : Metamorphic rock
<span>The answer is: energy source. In the process of photosynthesis, the sunlight is used as the energy source. Plants use the energy of the sunlight to convert it into chemical energy stored in carbohydrates. The general reaction of photosynthesis includes conversion of carbon dioxide and water into glucose and oxygen using the energy of sunlight. </span>
Answer:
Marker proteins are proteins that are incorporated in the cell membrane of a cell and based on these marker proteins a cell is identified. These proteins are very important while considering an organ transplant. If the marker proteins of the donor organ are not similar to the marker proteins of the original organ of the patient, then the immune cells will recognize the organ as foreign and the transplant will be rejected.
