A hypothesis refers to a suggested illustration for a phenomenon. For a hypothesis to be a scientific hypothesis, there is a need to test it. Upon analysis, a hypothesis can be modified or rejected, but it can never be proved 100 percent accurate.
A hypothesis needs more work by the individual testing it in order to either disprove or confirm it. A working hypothesis refers to a hypothesis, which is tentatively accepted as a foundation for a further research.
Answer;
Heterozygote advantage occurs when heterozygotes have a higher fitness than do both homozygotes. In frequency-dependant selection, the fitness of a phenotype declines it it becomes too common in the population.
Explanation;
The heterozygotes have both alleles, which is needed for genetic variation. Heterozygotes are essential for there to be genetic variation in a population. In other words it is when When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. For example a sickle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
-Frequency-dependent selection occurs when the fitness of a genotype depends on its frequency. It is possible for the fitness of a genotype to increase (positively frequency-dependent) or decrease (negatively frequency-dependent) as the genotype frequency in the population increases.
Bromothymol blue (BMB) is an indicator dye that turns yellow in the presence of acid. When
carbon dioxide is added to the solution, it creates carbonic acid, lowering the pH of the
solution. BMB is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and
yellow when the pH is less than 6
Most eukaryotic cells have mitochondria, which produce ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial inner membrane, electrons from NADH and FADH2 pass through the electron transport chain to oxygen, which is reduced to water
