Answer: Option B) NADH and FADH2
Explanation:
The purpose of the Krebs cycle is to convert potential chemical energy into metabolic energy in the form of ATP that can be used by the body.
Hence, the products of the Krebs cycle include:
- 3 molecules of NADH,
- 1 molecule of FADH2,
- 1 molecule of GTP,
- 2 molecules of CO2
Thus, NADH and FADH2 are two of the products of Krebs cycle.

Answer:
The natural selection on polygenic traits affects selection.
Explanation:
The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.
This occurs in three ways that are disruptive selection, stabilizing and directional selection.
