Answer:

question 1 :-Which gas is formed during respiration? Give a reason for your answer.

answers no 1

During respiration, complete oxidation of carbohydrates takes place. Glucose is broken down by oxygen to release energy, while carbon dioxide and water are the by-products of the reaction. The released energy is used to make a special energy molecule called Adenosine triphosphate (ATP).

Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Energy is released in the reaction.

question no 2 you were to blow on a mirror what would you expect to happen and why

answers no 2

Our breath is warmer than glass which is known as condensation, also our breath consists of water molecules. So whenever you blow air, the water molecules in our breath gets condensed and the mirror surface appears foggy. Contact with the glass is enough to cool the temperature and condense the moisture
