Charles Darwin observed that the accumulation of gradual changes in a population leads to a new species over time.
Further Explanation:
Scientific experimentations are the logical and practical procedures that determine the efficiency of a particular claim using scientific means. Charles Darwin was the one who gives the theory of evolution that occurred by natural selection. According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and became new species. Natural selection is the reason why the population grows adapted for well suited to the environment over time.
The pre-existing heritable variation in the group is the prime condition for natural selection to happen in the environment between the species. Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the atmosphere thus evolving the species. In Darwin's book ‘The Origin of Species’, all these facts and information are mentioned, and the ideas of evolution and natural selection are well-reflected.

Answer:
e. can produce genetic diverisity that may enhance survival of a population in a changing environment.
Explanation:
Genetic diversity is the amount of variation present in the genetic characteristics of an individual. It is basis for selection.
Random mating among individual which is done through sexual reproduction allows for variation in the population and diversity. Genetic diversity ensures continuity and adaptation of individual to adverse environmental condition, it is the basic for evolution.
Genetic diversity is also caused by various recombination, mutations and crossing over effect of homologous Chromosome.
Genetic diversity aids selection for improvement of various character.
B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.
D.) The new compounds that are formed must be more complex than the food molecules that were broken down.
