Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).

Answer:
B) Glycolysis involves the oxidation of NADH to produce NAD.
Explanation:
Glycolysis is the common step of aerobic and anaerobic respiration. It includes splitting of a glucose molecule into two molecules of pyruvate. During the redox reactions of glycolysis, NAD+ serves as an electron acceptor.
Reduction of NAD+ during glycolytic reactions produces NADH which in turn is oxidized back through oxidative phosphorylation in aerobic respiration.
The entry of one glucose molecule into glycolysis and its splitting into pyruvate uses a total of 2 molecules of NAD+ as the electron acceptor and produces 2 molecules of NADH.
