Answer:
Epistatic interaction of the two genes
Explanation:
In epistasis, the interaction between genes contradics one another, in essence, one gene masks the interference with the expression of another gene. As such any time two different genes contribute and have effects to a single phenotype and their effects are not merely additive, those genes are said to be epistatic.

Answer:
(A) A transversion base substitution causing a missense mutation
(B) A transition base substitution causing a silent mutation
(C) A transversion base substitution causing a silent mutation
Explanation:
There are two types of base substitutions, transversions and transitions. A transition is when the a purine base is substituted with another purine base or a pyrimidine base is substituted with a pyrimidine base (e.g. Purines - A to G; G to A; Pyrimidines - C to T; T to C). A transversion occurs when a purine base is substituted with a pyrimidine base or a pyrimidine base is substituted with a purine base (e.g. A to T; C to A).
There are three main types of mutations, these are missense mutations, nonsense mutations and silent mutations. Missense mutations occur when a base is changed and the codon now codes for a different amino acid to before the mutation. Nonsense mutations occur when a base is changed and now the codon codes for a stop codon causing a premature stop of the translation process. Silent mutations occur when a base is changed but the new codon still codes for the same amino acid as before the mutation.
If enough ejecta (mainly ash) is sent into the upper atmosphere, the dust particles will block solar energy causing a decrease in temperature. This has happened in the past. Look for the year without summer caused by a volcanic eruption.
Answer:
Generalist
Explanation:
Living Organisms able to exists in different types of environment and have different types of food are called "Generalist"<u>Raccoons</u> are the best example of generalist. they are extended from North to Central America . they are able to survive even by consuming human garbage .It is this quality make them to thrive in different types of environment.
