frozen [14]

Answer:

Disruptive Selection.

Explanation:

Disruptive selection, also known as selection diversification, explains shifts in population genetics that prefer extreme values for a trait over intermediate values. In this case, trait variation increases, and the population is split into two different classes. So, in the given case where A "U-shaped" distribution for a trait, with high frequencies of individuals who exhibit extreme values for a trait (and few individuals with medium values), is most likely to be caused by Disruptive selection.

As mean arterial pressure increases, the ________, informing the medulla oblongata that blood pressure has indeed increased.
finlep [7]

As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.

  • Special receptors called baroreceptors monitor variations in your blood pressure.
  • The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
  • Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
  • The brain interprets the information that the baroreceptors send as a rise in blood pressure.
  • The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.

In my opinion I think the main events of glycolysis. How many ATP molecules are produces and consumed by glycolysis? What effect
svlad2 [7]

Glycolysis uses 2 ATP and produce 4ATP. So the net gain is true.

Oxygen is used in the Electron Transport Chain as the final electron recipient from complex 4 cytochrome a₃.

Explanation:

Glycolysis is the process which is common in all forms of respiration where glucose is metabolized into pyruvate. This process is very essential to continue the next steps of different respiration. Glycolysis requires 2 molecules to process substrate level phosphorylation to convert glucose to glucose 6 phosphate and fructose 6 phosphate to fructose 1, 6 bisphosphate. But it produces 4 ATPs. Thus net gain is 2ATP.

In ETC, the hydrogen carriers NADH and FADH gives off the hydrogen to reduce the complex 1 and 2 respectively and itself gets oxidized. Thus the electron given off is transferred between 4 complexes to finally give off to oxygen to form water.
