Answer:
Explanation:
The difference between the homozygous and heteozygous in terms of genotype and phenotype is
For homozygous: an homozygous individual can carry similar alleles for a trait for example similar dominant alleles (FF) as the genotype and show a phenotype of black fur for the dominant allele and an homozygous individual can also carry the recessive allele (ff) as the genotype but show a phenotype of white fur
But for the heterozygous individual: the individual carries two disimilar alleles for a trait eg carry both the dominant and the recessive alleles. For example (Ff) as the genotype and showing black fur as the phenotype.

Answer:
Concentration gradient
Explanation:
When the concentration of molecules and ions is compared to the concentration of ions and molecules in another area, the difference in the concentration will be called the concentration gradient.
The concentration gradient is the factor which determines the rate and direction of the molecules and ions in the environment which could be physical or biological.
Thus, concentration gradient is the correct answer.
Answer:
c, disruptive selection
Explanation:
Disruptive selection is a term used to describe population genetic changes that simultaneously favor individuals at both ends of the distribution. When disruptive selection operates, individuals at the extremes contribute more offspring than those with intermediate characteristics, producing two peaks in the distribution on a graph.
In the excerpt shown in the question, long-gill-striped and gill-striped fish were favored by the selection process than intermediate-length striped fish. For this reason we can conclude that a disruptive selection was taking place.
