Explanation / Answer
7)
Vinegar lowers the levels of potassium (K+) ions in the bones as a results osteoporosis. It is a progressive bone disease that is characterized by a decrease in bone mass and bone mineral density that is associated with an increased risk of fracture and weak bones.
Thus, the correct option is (a) weakened bones.
8)
The antagonistic muscle pair of upper leg is hamstrings. For example, the deadlift requires picking up a weight from the floor up, this requires hamstring muscles on the back of the leg, and lower back muscles. Squat requires the quadriceps in front of the leg, and hip muscles.
Thus, the correct option is (c).
9)
The muscles contraction in which the tension rises but the length of muscles does not change is known as the isometric contractions. So, in the isometric contractions the muscles do not change length during contraction.
Thus, the correct option is (True).
10)
False, it is not an isometric exercise, because muscle contraction takes place.
