respiration.

3. Why do we often sneeze when we inhale a lot of dust-laden air.

Answer 2

Answer:

3.Sneezing expels the foreign particles from the inhaled air, so that only clean air enters our body. It usually occurs because of the irritation in the upper breathing passage. This irritation happens when we inhale some unwanted particles and they get trapped in our nasal cavity. Smoke, dust, pollen, etc. are some of the unwanted particles that may cause sneezing.

1.An athlete needs to supply extra energy to his muscle cells which have worked hard during running. For this, he breathes faster and deeper so that more oxygen is supplied to the cells. This speeds up the breakdown of food and as a result, more energy is released.

2.Similarity between aerobic and anaerobic respiration:

In both aerobic and anaerobic respiration, the food is broken down to release energy.
