The definition of Epistasis in gene biology is Choice D: when the allele of one gene masks the phenotype of another gene
Definition:
When the phenotypic effect of alleles at one gene are masked by alleles of another gene.
In essence, a gene is said to be epistatic when its presence suppresses the effect of a gene at another locus.
It is important to know that Epistatic genes are often called inhibiting genes because of their effect on other genes which are described as hypostatic.
Additionally, there are six common types of epistasis gene interactions:
- Polymeric gene interaction,

<span>A person who eats and sleeps too much is experiencing a depressive episode with psychotic features. Psychotic features can impact a person's mood negatively and cause them have hallucinations or delusional feelings of depressive themes such as worthlessness or lacking a sense of self-worth.</span>
Heterotrophs help in maintaining a balance in the ecosystem by providing organic compounds for autotrophs. Certain heterotrophs such as fungi help in reducing decomposed plant and animal material. This recycling activity is important in reducing waste in the environment.

Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>
Explanation:
According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.
Based on the reactions:
Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc
Electron transfer reaction: Oxidases and dehydrogenases
Radical transfer reaction: Transglycosidases, transaminases, etc
Splitting or C-C bond formation: Desmolases
Structural or geometrical change: Isomerases
Hydrolysis of phosphate bonds to join molecules: Ligases
Based on the general principle of recommendations, enzymes are suffixed with –ase depending upon the catalytic reaction and substrate.
Explanation:
they include floodwalls/seawalls, floodgates,levees, and evacuation routes. Nonstructural measures reduce damage by removing people and property out of risk areas. They include elevated structures, property buyout, permanent relocation, zoning, subdivision, and building
