Answer:

Yes. Levels of Carbon dioxide must be equal in proportion to metabolic rate of the system.    is a product of cell respiration and should be monitored.

Explanation:

Levels of carbon dioxide must be equal in proportion to metabolic rate.

Carbon dioxide is a product of cell respiration and should be monitored to avoid surfocation and likes

As the  temperature of the system(or body) increases, oxygen level decreases leading to increase in carbon dioxide level which is very dangerous for any system or an organisms. This can leading to Astma and other respiration problems.

A population is composed of 1000 individuals, of whom 500 are dd, 140 are dd, and 360 are dd. what is the frequency of the d all
MA_775_DIABLO [31]

The frequency of the d allele is 0.6.

<h3>How to calculate the frequency of d allele?</h3>

According to the Hardy-Weinberg principle, which states that p² + 2pq + q² = 1, an equilibrium between the allele frequencies in a population of randomly mated individuals is created, and these gene frequencies are maintained over generations.

Here, p denotes the frequency of the "D" allele, and q denotes the population's frequency of the "d" allele.

Consequently, p² is a representation of the frequency of homozygous dominant DD.

The frequency of the homozygous recessive dd gene is represented by q².

The frequency of the heterozygous Dd allele is represented by 2pq.

According to the inquiry, there are 1000 people, and 360 of them are dd genotype carriers.

if q² = dd = 360/1000 = 0.36,

q = d = 0.6
