The Tasmanian tiger was a species that lived in Australia but is now extinct. Recent studies have shown that Tasmanian tigers had very low genetic variation, which likely contributed to their extinction. Why would there be a higher chance of extinction for species of low genetic variation?

(help please slam is hard)

A.

Such species produce too many offspring for the environment.

B.

Such species are less able to adapt to a changing environment.

C.

Such species are not able to mate with other populations.

D.

Such species cannot gather enough food for the population.

answer: oceans, duh

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.
