Who is a person who has one recessive allele for a trait and one dominant allele for the same trait?

The person is heterozygous for the trait. The person is a carrier of the recessive allele of the trait.

Explanation: Take for instance the height trait. If H is a dominant allele for tall height and h is recessive allele for short height, a person who has one recessive allele and one dominant allele will have a genotype of Hh, this means that the person is heterozygous for the trait. In this example, the genotype Hh will manifest outwardly as tall height because H is dominant over h.

hope this !

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
