Answer to Question 1

Ans:
D

Feedback:

Selye noted that stress can result in positive growth and development, and that stress is not unanimously detrimental to health and development. The alarm stage is associated with the release of cortisol and catecholamines, and a stress response is dependent on properties of the stressor and the individual's conditioning; the severity is not objectively determined. Illness is often a consequence of the exhaustion stage.

Answer to Question 2

Ans:
A, B, E

Feedback:

Slow-twitch fibers, which are smaller than fast-twitch fibers, tend to produce less overall force but are more energy efficient and better suited biochemically to perform lower-intensity work for prolonged periods. Examples of exercises that use slow-twitch fibers are long-distance running, swimming, and cycling, where endurance is desired. Fast-twitch fibers are suited for high-intensity workouts and utilize anaerobic metabolism.
