PLEASEEE HELP FAST! IT WOULD BE AWESOME ❤️2. Although Chargaff used DNA from both prokaryotic and eukaryotic organisms, there are several differences between the DNA in prokaryotes (like the bacteria Escherichia coli) and eukaryotes (lil-
turtles). Which of the following accurately describes one of these differences?
A. Prokaryotic cells only contain adenine and thymine, but no guanine and cytosine.
B. Prokaryotic cells contain circular DNA molecules called plasmids.
C. Eukaryotic cells have less DNA, and therefore fewer genes than prokaryotic cells.
D. Eukaryotic DNA is double stranded and prokaryotic DNA is single stranded.

Answer would be B

Explanation:

As Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.

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.
