Answer:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. ... Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce.
Answer No 1:
Process 1 is cellular respiration. Cellular respiration can be described as a process in which glucose and oxygen are converted into water and carbon dioxide. ATP is released by this process which is used as an energy source.
Process 2 is anaerobic respiration. It is a process which occurs in the absence of oxygen. This process will also yield ATP.
Answer No 2:
The process 1, cellular respiration, is known to produce 38 molecules of ATP. Out of these, 2 molecules are the result from the process of glycolysis, 2 molecules arise from Kreb's cycle, rest 34 are known to occur from the electron transport chain.
The process of anaerobic respiration is known to make 2 molecules of ATP in total.
