Xelga [282]

During isovolumetric phases of the cardiac cycle, the atria are contracting.

<h3>What happen in isovolumetric phases of the cardiac cycle?</h3>

The isovolumetric contraction occurs in isovolumetric phase that causes left ventricular pressure to rise above atrial pressure. This leads to opening of aortic valve at the end of isovolumetric contraction when left ventricular pressure exceeds aortic pressure.

So we can conclude that during isovolumetric phases of the cardiac cycle, the atria are contracting.

How are the results of genetic drift similar to the results of gene flow?
Fynjy0 [20]
The answer is Both result in a change in allele frequencies in the affected population

Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms. I<span>magine you have two different alleles in the population responsible for red and white color of a flower. Their allele frequencies are 0.2 for white flowers and 0.8 for red flowers. After some change in the environment, only white flowers survive. They will reproduce, and in the population, there will be only white flowers. The population for these flowers will increase from 0.2 to 1.
Speaking of gene flow, it is not as dramatic and drastic as genetic drift, but still, it includes a transfer of alleles from one population to another, so there is expected a change in allele frequency.</span>
