The semilunar valves of the heart open at the onset of the ejection period. Approximately what percentage of the stroke volume i
mr Goodwill [35]

The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%

<u>Explanation:</u>

The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.

Instead they will pump only a proportion of blood in each of the cardiac cycle.  The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.

How would you expect the pH of a lake with limestone bedrock to compare to other lakes after several years of acid rain?
NISA [10]

Answer:

The interpretation including its set of circumstances is characterized throughout the explanation segment below.

Explanation:

  • Lakes that always collect a significant amount of acid rain can also have water with either a pH value very low than 4. (the latter indicates that low pH levels are much more acidic versus significantly higher.)
  • The world's oceans are covered from ocean acidification by limestone formations, which serves as a barrier to neutralize acid rain.
