Which of the following do you find in prokaryotes, eukaryotes, and viruses?

a
all are living
b
DNA/RNA
c
all are non-living
d
ribosomes

b. DNA/RNA

Explanation:

Prokaryotes, eukaryotes, and viruses are composed of DNA or RNA molecule. DNA is a molecule which contains genetic information about growth, development, functioning and reproduction of all living organisms. Prokaryotes are organisms which have no true nucleus while eukaryotes have true nucleus. True nucleus means membrane present around the nucleus. Virus is the only organism which is considered as both living and non living.

sadness is not good

explanation:

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.
