Answer 2

Answer:

1.Muscle cramps occur when there is anaerobic respiration taking place in our muscles. During anaerobic respiration, glucose gets converted into lactic acid which leads to lack of oxygen. A hot water bath or a massage can help in getting relief from the muscle cramps.

2.Iron articles are painted because it prevents them from rusting. When painted, the contact of iron articles from moisture and air is cut off. Hence, rusting is prevented their presence is essential for rusting to take place.
