Notes of Chapter 10 for CBSE Class 7 on Vedantu
FAQs on CBSE Class 7 Science Respiration in Organisms Worksheets
1. Why does an athlete breathe faster and deeper than usual after finishing the race?
During the run, the energy demand is high but the supply of oxygen to produce energy is limited. Therefore, anaerobic respiration takes place in the muscle cells to fulfill the energy demand. After finishing the race, an athlete breathes faster and deeper than usual so that more oxygen is supplied to the cells.
2. Why do we often sneeze when we inhale a lot of dust-laden air?
When we inhale air containing dust particles, the particles get trapped in the hair present in nostrils. Sometimes, these particles may pass through the hair and enter the nasal cavity. They irritate the mucus lining of the nasal cavity, and as a result, we sneeze.
