Forces that cause a change in motion of an object are

The correct answer is "unbalanced forces".

Explanation:

Balanced forces are two equal forces that act in opposite directions in the same object, resulting in the object being apparently static. On the other hand, unbalanced forces cause a change in motion because the forces that act on it are not equal in size or direction. The force that results from the two forces is known as the resultant force and is the one that provokes the motion of the object.

protein synthesis is an example of feedback mechanism which in homeostasis

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.
