Homozygus- same
the PP are the same allele
The genotype would be 100% homozygus and then whatever the P stands for.
Homozygus P
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.
Answer:
1.) A factory produces chemical waste and releases it into a water system
2.) Water becomes polluted in nearby rivers and streams
3.) Aquatic plants stop thriving
4.) Small fish do not have adequate food
5. Larger fish have less prey to eat and their numbers decline
The risk of lung cancer death is no different between medium, low, and very low-tar cigarettes.
People who smoke low-tar cigarettes compensate the lack of tar by changing their breathing habits, for example, they will take deeper drags or hold the smoke in for a longer period of time, basically negating the supposed " low-tar" effect.
