The map shows an island arc in Alaska named the Aleutian Arc. What does the arc suggest about its surrounding geographic region? A. The region lies on a transform boundary.
B. The region is affected by a subduction zone.
C. The region has a hot and humid climate.
D. The region might have active volcanos
E. The region is close to the convergent boundary.

The answer is B.

Reason:

The Aleutian Arc volcanism is the result of the active subduction of the Pacific Plate beneath the North American Plate.

the correct answer is - ability to find a mate

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.
