Mendel established several principles of heredity from his experiments and observations. What did he conclude regarding the inheritance of genes from parents?

A. Offspring inherit two copies of each gene from the dominant parent.
B. Offspring inherit one copy of each gene, and some genes are inherited from one parent and some from the other parent.
C. Offspring inherit two copies of each gene, one from each parent.
D. Offspring inherit one copy of each different allele that exists for a gen

B is the correct answer

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.
