Answer:
<h2>D. All of the choices are correct.
</h2>
Explanation:
In a process called non-cyclic photophosphorylation ( light-dependent reactions), electrons are removed from water and passed by different electron carries like Pq, Pc and cytochrome complex and many others, through PSII and PSI before ending up in NADPH.
These are the basic steps of non-cyclic photophosphorylation:
i)Light absorption in PSII (P680)
ii) ATP synthesis.
iii)Light absorption in PSI (P700)
iv) NADPH formation.
The answer to this is genetic diversity. Genetic Diversity is the total number of genetic makeup of a species. It distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. <span />

The lymphatic vessels are thin-walled valvular structures, composed of lymphangions, which carry the lymph from the tissues, via the lymph nodes, to the bloodstream. For this reason, they are analogous to veins and venules.
The lymphatic network is present throughout the body with the exception of the central nervous system and non-vascularized tissues.
It is separated in two circuits: one for the upper right quarter of the body, and one for the rest.
The lymphatic channels join together to form lymphatic vessels more and more voluminous.
Finally, The lymph is drained by two large collectors:
* The right lymphatic canal
* The thoracic duct.
All lymphatics thus end up in the upper vena cava system by two separate circuits.
<span>A certain virus infects one in every 200 people. A test used to detect the virus in a person is positive 90% of the time if the person has the virus and 5% of the time if the person does not have the virus. (This 5% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive".
