Sexual reproduction .a. enables males and females to remain isolated from each other while rapidly colonizing habitats. b. allows all animals to conserve resources and reproduce only during optimal conditions. c. yields more numerous offspring more rapidly than is possible with asexual reproduction. d. guarantees that both parents will provide care for each offspring. e. can produce genetic diverisity that may enhance survival of a population in a changing environment.

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.

Explanation:

Carbohydrates

Monomer- monosaccharide

Polymer- polysaccharides

Fats

There is no monomer of fat, but dehydration synthesis bonds glycerol and fatty acid tails.

Nucleic Acids

Monomer- nucleotides: a five-carbon sugar, a phosphate group, and a nitrogenous base

Polymer- nucleic acids
