How many trips has earth made around the sun in 8 mar years

The answer is;  15 years

It takes 687 days for mars to orbit the sun once. 8 mars years would, therefore, mean;

8 * 687 = 5496 days

The earth takes 365 days to orbit the sun  once. Therefore, the earth will orbit the following number of times in 8 Mar years;

5496/365 = 15.058

Which is approximately 15 years

doctors i believe if i'm wrong sorry

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.
