Answer:
1. This is due to the fact that the temperature in summer is high (than that of the winter) due to which the rate of diffusion (intermixing to two particles) is high in summer.
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.Feeling very tired is one of the most common symptoms of iron deficiency. This symptom is common in people who don't have enough iron . This fatigue happens because your body lacks the iron it needs to make a protein called hemoglobin, which helps carry oxygen around the body.
