Answer:
Genetic drift is referred to the changes in allele frequency in a gene pool. Gene flow is the process of alleles moving from one population to another.
Explanation:
b) If Sally's parents have another child what is theprobabilty that this child will have alkaptonuria?
c) If Sally marries a man with alkaptonuria, what is theprobability that their child will have alkaptonuria?
If Sally marries a man with alkaptonuria, there is a 50% chance that their child will have alkaptonuria.
The genotype of an individual refers to the sum total of genes that the individual received from its parents. Since Sally has a normal metabolism, Sally is Aa. Sally's mother is Aa while Sally's father and brother are aa.
If Sally parents have another child, using the Punnet square method, there is a 50% chance that the child will have alkaptonuria. If Sally marries a man with alkaptonuria, there is a 50% chance that their child will have alkaptonuria.

a) Genotypes: : Aa (carrier of the alkaptonuria allele) ,Mother: Aa (carrier of the alkaptonuria allele)Father: aa (has alkaptonuria)Brother: aa (has alkaptonuria)
b) If Sally's parents have another child:The probability of the child having alkaptonuria (aa genotype) is 25%.The probability of the child being a carrier (Aa genotype) is 50%.The probability of the child having normal metabolism (AA genotype) is 25%.
c) If Sally marries a man with alkaptonuria (aa genotype):The probability of their child having alkaptonuria (aa genotype) is 50% (as Sally is a carrier).The probability of the child being a carrier (Aa genotype) is 50%.
The probability of the child having normal metabolism (AA genotype) is 0% (as the husband has alkaptonuria).
Sally: Aa (normal metabolism carrier)
Mother: Aa (normal metabolism carrier)
Father: aa (alkaptonuria)
Brother: aa (alkaptonuria)
b) If Sally's parents have another child:
Probability of the child having alkaptonuria (aa genotype) is 25%.
Probability of the child being a carrier (Aa genotype) is 50%.
Probability of the child having normal metabolism (AA genotype) is 25%.
c) If Sally marries a man with alkaptonuria (aa genotype):
Probability of their child having alkaptonuria (aa genotype) is 50% (as Sally is a carrier).
Probability of the child being a carrier (Aa genotype) is 50%.
Probability of the child having normal metabolism (AA genotype) is 0% (as the husband has alkaptonuria).

Answer:
The correct answer would be - Species removal experiment and the DeWitt Replacement experiment.
Explanation:
The competition can be increase for the various resources such as habitat, nutrients, water, and many more due to the territorial behavior of interspecific species.
The influence of the interspecific behavior such as competition influences on the population size of the species, two important tests are used are species removal experiment, and DeWitt Replacement exp commonly eriment.
Thus, the correct answer is - Species removal experiment and the DeWitt Replacement experiment.

Answer:
Organism, population, biological community, ecosystem, biome, and biosphereThe atmosphere is the part of the biosphere that describes the gasses on earth. The hydrosphere is the part of the biosphere that accounts for all of the water on the entirety of the surface of earth. The lithosphere is the part of the biosphere that captures all of the land masses on the earth’s crust and in the oceans.

Explanation:
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning. So the cell dies because it cannot function properly.
