Answer:
This question lacks options, options are:
a) The partial pressure of oxygen
b) Acidity
c) The partial pressure of carbon dioxide
d) Temperature
e) BPG
The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen
</u>.
Explanation:
Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.
Answer:
<u>Uranium</u> is the inner transition metals is critical to the nuclear power industry.
Explanation:
Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.
Answer:
c) Habitat isolation
Explanation:
Habitat isolation is a mechanism that prevents species from mating even if they don't have reproductive barriers. The differences in the habitat types may thus be sufficient to develop reproductive isolation between two (or more) populations
