Answer: G. thymosin and thymopoietin
Explanation:
The thymus produces and secretes thymosin, a hormone necessary for T cell development and production. The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat.
Answer:
fluvial wetlands
Explanation:
The earliest megafossils of land plants were thalloid organisms, which dwelt in fluvial wetlands and are found to have covered most of an early Silurian flood plain. They could only survive when the land was waterlogged.
Answer:
NADPH is formed on the stromal side of the thylakoid membrane, so it is released into the stroma. In a process called non-cyclic photophosphorylation (the "standard" form of the light-dependent reactions), electrons are removed from the water and passed through PSII and PSI before ending up in NADPH.
<span>It is going to depend on what you consider stable. A
diverse population would be more resistant to disease because of simple
biology. The more sources for possible resistance the better the
heterogeneous pool will be at resisting disease. You also have to take
in to consideration things like the availability of modern medicine and
the ability to be isolated during illness. </span><span>
Personally I think it has to do with the fact that many of the worlds
more diverse population centers are also many of the worlds largest
population centers which make them less prone to invasion on that basis
alone. </span>
