Which of the following can result in speciation from bio geographic isolation

Biology
1 answer:
kozerog [31]3 years ago
3 0

The effect of geographic isolation is that the two populations are subjected to different selection (pressures) and geographic conditions. The conditions in the two areas, if different, will produce different alleles in that species and will be selected for, where genetic differences will gradually accumulate between the two different populations.

In time, enough genetic differences will occur so that the two populations will no longer interbreed. Then, by definition, they have become different species.

7. Phytochrome prevents seeds of some plants from germinating when they are in deep shade by the: absorption of far-red waveleng
SIZIF [17.4K]
<h2>Function of Phytochrome </h2>

Explanation:

  • The <em>color of light</em> that they absorb maximally by the two types such as   <em>Pfr is a blue-green structure</em> that ingests far-<em>red light (730 nm)</em> and<em> Pr is a blue structure that retains red light (660 nm)</em>
  • <em>Pfr assimilates far-red light</em>, it is changed over to the <em>Pr structure</em>
  • Pfr can spontaneously revert to the Pr form  structure in obscurity <em>dark over time = dark reversion Pfr</em> is additionally helpless to proteinases
  • <em>Pfr contains  some red light, so in red light 15% Pr and   there is a parity of 85% Pfr.</em>
  • <em>The  phytochrome (Pr)</em> is changed over to the organically dynamic structure red light with the <em>Pfr under illumination</em>
  • <em>Darkness and Far -red light convert</em> the particle back to the inactive form.

If the bicuspid (mitral) valve is not fully closing, does pulmonary circulation increase, decrease, or not change?
elena-14-01-66 [18.8K]

Answer: Decrease

It will decrees because required volume of blood will not be   emptied into the pulmonary circulation  to reach the lung for oxygenation. Rather blood flows back into the  Right  atrium ,(regurgitation,) through the these valves   during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which  reduces blood flow leading  to volume overload  in  the heart. Eventually this  affects systemic circulation,
