The saturation of hemoglobin is __________% at the arterial PO2 of 95 mmHg, and is __________% at the venous PO2 of 40 mmHg.
ra1l [238]

The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg

<h3>Saturation of Hemoglobin</h3>

The saturation of hemoglobin at the arterial PO₂ is 100 percent due to the constant supply of oxygen taken in from the environment. while at the venous PO₂ the hemoglobin is 75% due to the limited supply of oxygen.

Hence we can conclude that The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg.

In a population of plants, the allele for long stems is completely dominant over the allele for short stems. If 35% of the popul
KatRina [158]
Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of <span>evolutionary influences such as </span>mate choice<span>, </span>mutation<span>, </span>selection<span>, </span>genetic drift<span>, </span>gene flow<span> and </span>meiotic drive<span>.
</span>
Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x  (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where 
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2

Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population

Answer: percentage of heterozygous population is 48.32%

Describe in detail how gases are exchanged between the respiratory system and the circulatory system in the lungs
charle [14.2K]

Answer:

Gas exchange

Explanation:

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
