Explanation:
1.Symptoms of marasmus
chronic diarrhea.
respiratory infections.
intellectual disability.
stunted growth.
2.Fe(s)+CuSO4 ⟶Cu(s)+FeSO4
When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green. This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe 2+ ions and ferrous sulphate solution is formed.
3.Your body is constantly losing water through breathing, sweating, and urinating. If you do not take in enough fluids or water, you become dehydrated. Your body may also have a hard time getting rid of fluids. As a result, excess fluid builds up in the body.
