Answer:
The species is extinct.
Explanation:
Endangered signifies that species will soon go extinct.

>Heat doesn't provide the activation energy for their reactions.
Answer:
A molecule with 32 percent or more amount of Cytosine.
Explanation:
DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.
The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.
Thus, the answer is molecule with 32 percent or more amount of Cytosine.
All of the factors are responsible for unloading of oxygen from the hemoglobin molecule except the increase in partial pressure of oxygen.
Because the affinity of haemoglobin for binding oxygen increases as partial pressure of oxygen rises.
<h3>What is Haemoglobin?</h3>
Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.
<h3>What are factors that affect Haemoglobin's affinity for oxygen?</h3>
- When used as an oxygen transporter, hemoglobin can carry about 65 times as much oxygen as simple solution in plasma could.
- A cooperative oxygen-hemoglobin affinity is produced by conformational changes in the molecule.
- The oxygen-hemoglobin dissociation curve's sigmoidal form reflects this characteristic.
- Temperature, hydrogen ions, carbon dioxide, and intraerythrocytic 2,3-DPG all have an impact on hemoglobin's affinity, and they all interact with one another.
