Answer:
Human beings branched from a common ancestors along with primates, but fall into a different group called the hominids, and homo sapiens (modern man) is the only specie of this group to have survived to our time.
Explanation:
Evolution is the the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.
There is a strong assertion of an evolutionary link between humans and chimpanzees from evidences of evolution. Usually, organisms that evolved from a common ancestor share certain structures in common. This asserts the authenticity of an evolutionary link between species.
Answer:
In muscle cell, fermetation produces <u>"lactate and NAD"</u>
<u>In fermentation Pyruvate is reduced and __NADH__ is oxidized.</u>
Explanation:
Muscle cells perform lactic acid fermentation when enough oxygen is not available to support aerobic cellular respiration. The process of glycolysis forms two molecules of pyruvate from one glucose molecule and uses NAD+ as electron acceptor. During lactic acid fermentation, pyruvate is reduced into lactate and NADH serves as an electron donor. The final products are lactate and NAD+. The reaction is catalyzed by lactate dehydrogenase enzyme. The NAD+ produced by fermentation is required to continue the process of glycolysis.
Answer:
I know it is jj. The answer is maybe that.
It weakens the immune system making it unable to defend itself against viruses and it also attacks the immune system..
