D. This is a contemporary issue due to global warming, etc
The function of the respiratory system is to move two gases: oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them
The percentage of hemoglobin that will be saturated when the PO2 is 20 mmHg is 20%.
<h3>Why is it beneficial for the hemoglobin near these tissues to NOT pick up oxygen?</h3>
It is recommended that the tissues do not absorb oxygen at this point because the affinity of hemoglobin for oxygen will be low since the medium will be acid due to the amount of hydrogen ions and carbon dioxide, situation that occurs in tissues where oxygen is metabolized quickly. Therefore, then there will be no absorption of oxygen from these tissues, but rather it will occur in oxygenated tissues such as the lungs. This is an effect called the 'Bohr effect' and allows oxygen to be released where it is most needed.
And the percentage of oxygen saturation will be 20% according to the hemoglobin saturation curve.

Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
