Neptune is about 5 au from the sun is the only outer planet without rings was the first planet to be discovered using a telescope was predicted by abnormalities in uranus' orbit

D

Explanation:

It is 30 AUs so the first answer is incorrect.

It does have rings although they are fragmented and very hard to see. B is wrong.

No Neptune was not the first to be discovered by telescope. Uranus was.

It was found because it did cause abnormalities in Uranius' orbit.

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.

yes? sounds right, but you didn’t ask a question.
