Answer:
120 mm Hg
Explanation:
Given that,
Height = 8022 ft/2445 m
Atmospheric pressure = 570 mm Hg
In order to calculate the partial pressure of oxygen, at first, it is required to calculate the mole fraction of Oxygen.
Mole fraction of Oxygen = % of Oxygen in the air
= 20.95 % = 0.2095
Now, we know that,
⇒ Partial pressure of oxygen = Total pressure × mole fraction of Oxygen
= 570 × 0.2095
= 119.415 mm Hg
Therefore, the partial pressure of oxygen in Vail is approximately 120 mm Hg.

Answer:
b. Mutualistic
Explanation:
The symbiotic relationships are defined by the interacition between two species, In the mutualistic symbiotic relationship both of the organisms get benefits from the interaction. in the case of the normal flora in the skin as they compete with pathogens for space and food they prevent this patogens to go in the human skin, and they get food from the skin, so as they give protecttion and obtain food, both of the organisms are getting benefits and because of this:
The relationship between you and your normal flora is an example of a mutualistic symbiotic relationship.
