Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.

Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
chromosomes or by differences in the genes carried by the chromosomes. Eye colour, body form, and disease resistance are genotypic variations. Individuals with multiple sets of chromosomes are called polyploid; many common plants have two or more times the normal number of chromosomes, and new species may arise by this type of variation. A variation cannot be identified as genotypic by observation of the organism; breeding experiments must be performed under controlled environmental conditions to determine whether or not the alteration is inheritable.
Genotypic variations are caused by differences in number or structure of Environmentally caused variations may result from one factor or the combined effects of several factors, such as climate, food supply, and actions of other organisms. Phenotypic variations also include stages in an organism’s life cycle and seasonal variations in an individual. These variations do not involve any hereditary alteration and in general are not transmitted to future generations; consequently, they are not significant in the process of evolution.
