Tracy had taken tennis lessons when she was very young and was a good tennis player while she was in school. However, she had not played tennis for years when she decided to enroll in a tennis class at college. At the tennis class, a moment after she picked up her racket, Tracy realized that she had shifted it to the correct forehand grip without even thinking. Tracy's made this possible. Select one: a. implicit memory b. semantic memory c. psychomotor memory d. episodic memory

A. Implicit Memory.

Explanation:

  This form of memory presumably uses past experiences to remember things without thinking about them. It brings about the exhibition of past experiences, no matter how long ago those experiences occurred. It happens like an automatic response to the event been called to.

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.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
