Answer:
In building a tree, we organize species into nested groups based on shared derived traits (traits different from those of the group's ancestor). The sequences of genes or proteins can be compared among species and used to build phylogenetic trees.
Explanation:
The answer is NAD+.
In the process of glycolysis, NAD+ is reduced to form NADH+ and H+. If NAD+ is not present, glycolysis will not be able to continue. Under anaerobic conditions, the regeneration of NAD is coupled to the reduction of pyruvate. The anaerobic regeneration of NAD is called fermentation.
In animal tissues , fermentation occurs as pyruvate acts as a makeshift hydrogen acceptor and gets reduced to lactate when NADH transfers electrons to pyruvate. This enzyme catalyzed reaction occurs whenever the available oxygen has been consumed.
amino acids and ammonia are the two types of nitrogen that are usable by humans.
