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.

The tertiary structure of a polypeptide is the Select one:_________
Rufina [12.5K]

Answer:

The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.

Explanation:

A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to  stabilize many polypeptides.

Answer:

1. Chloroplast

2. cellular respiration

3. ATP

4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

Explanation:

This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:

6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)

Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:

C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy
