Explanation:
1.Sugar is dissolved in the water from milk. Hydrogen from water is bonded to OH- from sugar.
2.Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere.
3.The surface of earth is an efficient filter and probably one of the best filters it not only filters the harmful waste after decomposition by detritus of grazing food chain but also makes it usable as later source of fossil fuels. It acts as a filter for waters even with a very low pH which is very highly acidic
4.As the name implies, iron deficiency anemia is due to insufficient iron. Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath
