Answers
Explanation:
(1) in walking and jogging , enough amount of oxygen can be taken to breathe so it is an aerobic exercise...whereas during running, adequate amount of oxygen can not be taken and thus we face suffocation hence anaerobic exercise .
(2) at night carbon dioxide amount is very high especially under a tree because at night trees respire, ie , they give out carbon dioxide....so we may inhale carbon dioxide gas which is harmful.
(3) The end product of Photosynthesis is glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
(4) Plants do not need respiratory system because roots , stems, leaves of plants exchange gases for respiration separately. ... They don't have lungs to breathe so they don't need a respiratory system. They have stomata.
(5) Plants respire all the time, day and night. But photosynthesis only occurs during the day when there is sunlight. Depending on the amount of sunlight, plants can give out or take in oxygen and carbon dioxide.
