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:
0
Explanation:
You cant, not because of breathing but because of O3 and atmosphere. If there is no oxygen all things will instantly crash.
Answer:A. allow them to see over a wider area to detect predators
Explanation:This helps them because it gives them a large field of view, from which to avoid predators.
Answer:
c. The ratio of long to short fatty acid tails in the membrane phospholipids increases
e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids
Explanation:
In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.
Answer:
<u>Ff</u>
Explanation:
The allele representing freckles is "f".
Heterozygous alleles have to have two different components (e.g. Ff) because the term <em>hetero</em> means<em> different</em>.
