Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.

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

What is the thin layer of endothelial tissue that lines the inner surface of the heart and the valves called

serious [3.7K]

Answer:

Endocardium

Explanation:

The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.

The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.
