Answer: If red light is shined on a population of red walking beans then they would not be as red as when started because they need light to survive and red light is present but they reflect it until they need it to survive.
Mutations that naturally occur can change phenotype and if it is beneficial to the species then it will be past on if it is no then it will die before passing it on.
All cells have a nucleus in the middle of it (Hope that helps)
Mutations have an important role in how species change over time.
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.
