PLEASE HELP Which statement is true about the forces involved in an ornithopter and a pterosaur taking off

a

Gravity acts on both the ornithopter and the pterosaur.

b

Drag acts only on the ornithopter and not on the pterosaur.

c

Thrust resists the motion of the pterosaur and the ornithopter.

d

Lift is the single major factor in the forward movement of the ornithopter.

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.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

option c is the correct answer.
