Since, the options are not given the question is incomplete. The complete question is as follows:
A serving of food that has 10% to 19% of a nutrient based on a 2,000-calorie diet is considered to have __________. A. low nutritional value B. good nutritional value C. average nutritional value D. excellent nutritional value
Answer: B. good nutritional value
Explanation:
The average person needs 2,000 calories a day. If the food contains the daily value of 5%, then it can be considered to be low in the nutrient content, whereas a food source that consists of 10% to 19% of the nutrient content then it can be considered as a good source of nutrition. If the food consists of 20% of the nutrient content then it can be said as the excellent source of nourishment.
There are three types of muscle contraction: concentric, isometric, and eccentric.
Concentric: In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.
Isometric: An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint.
Eccentric: An eccentric (lengthening) muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself, resulting in the forced lengthening of the muscle-tendon system while contracting
