Yuki888 [10]

<h2>Adenosine triphosphate</h2>

Explanation:

ATP, or adenosine triphosphate, is synthetic vitality the cell can utilize.
The particle gives vitality to your cells to perform work, for example, moving your muscles as you stroll down the street.When ATP is separated into ADP (adenosine diphosphate) and inorganic phosphate, vitality is discharged.
ATP is converted into ADP which can be recycled back into ATP Is Converted into A waste product that The cell excretes ATP Is broken down into its individual parts and would need to be re-made Through metabolism to be used again.
At the point when one phosphate bunch is expelled by breaking a phosphoanhydride bond in a procedure called hydrolysis, vitality is discharged, and ATP is changed over to adenosine diphosphate (ADP).
ATP works as the vitality cash for cells. It permits the cell to store vitality quickly and transport it inside the cell to help endergonic concoction reactions.
As ATP is utilized for vitality, a phosphate gathering or two are withdrawn, and either ADP or AMP is created.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?

Brilliant_brown [7]

Answer:

(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Explanation:

As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.

Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.

This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t

Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² + 2pq+ q² = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = $\sqrt{0.35}$ = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.
