Answer 2

The answers to the questions are as follows:

1. c) Both types of fibers depend on genetic factors.

• There are two types of muscle fibers: Slow and Fast twitch.
• Slow-twitch fibers respire aerobically (use oxygen) while fast-twitch fibers rely on anaerobic respiration.
• The percentage abundance of each is mainly controlled by the genes.

2. (b) Bowlegs are not related to spinal curvature deformities.

• In bowleg syndrome, the person's legs have an outward curvature. There is a deformity in the bone structure around the patella (the knee cap).

3. In 1900, women competed in the Olympics for the first time.

• The 1900 Paris Olympics witnessed the participation of twenty-two female athletes.
• The participation of women has tremendously increased since then.

4. They secured medals in the 2012 Olympics.

• Saina Nehwal won a bronze medal in Women's Badminton Single.
• M.C. Mary Kom won a bronze medal in Women's Boxing.

5. In the 1984 Olympics, P.T. Usha secured 4th place.

• In 1984, the Olympics were held in Los Angeles.

6. All of the above are responsible for osteoporosis.

• Osteoporosis (weak bones due to low bone density) happens due to lack of calcium in the diet, or amenorrhoea (no menstrual flow), or some eating disorder.
