DochEvi [55]

Well,

We need to make a Punnett square. Assuming that the man has type A, not AO or AA blood, we will have a 1 x 2 Punnett square. We just have to take the A on the left and pair it with either the A on the left column or the B on the right column.

Therefore, the percent chance of having an AA genotype is 1 in 2 or 50%, while the percent chance of having an AB genotype is 1 in 2 or 50%. Thus, the possible phenotypes are 50% A type blood and 50% AB type blood.

I have attached the resulting Punnett square.

Answer:

Here are the following options to complete the question

Which of the statements below is the best explanation of why athletes would need to monitor lactate levels?

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

B. During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH.

C. During anaerobic respiration, muscle cells receive too little oxygen and begin to convert lactate to pyruvate (pyruvic acid), thus athletes experience cramping and fatigue

D. During aerobic respiration, muscle cells cannot produce enough lactate to fuel muscle cell contractions and muscles begin to cramp, thus athletic performance suffers.

A is THE CORRECT ANSWER

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

Explanation:

When the muscle cells undergoes anaerobic respiration, lactate are produced. Too much accumulation of lactate results in muscle fatigue. It is necessary for the athlete to prevent high accumulation by adjusting their exercise level

How breathing rate is controlled both consciously and subconsciously?

Travka [436]

Breathing is usually controlled subconsciously by the respiratory center at the base of the brain. Breathing continues during sleep and usually even when a person is unconscious. People can also control their breathing when they wish, for example during speech, singing, or voluntary breath holding.
Hope this helps:)
