Both of beth’s parents have brown eyes, but beth has blue eyes. what is the best explanation for why beth has blue eyes

Blue eyes is a recessive trait

Therefore it can be carried from generation to generation without being noticed

Both of Beths parents carried the recessive gene from their parents to Beth

Blue eyes is a recessive trait and blue eyes probably dominates the brown eyes.

Explanation:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
