A: When a person starts doing exercise, rate and
depth of breathing increases even before there
are changes in `pO_(2), pCO_(2)` or `H^(+)` concentration.
R: The main stimulus for these quick changes is
due to input from the proprioreceptors, which
monitor movements of joints and muscles.

Which of the following statements are CORRECT ? I. A specialized center present in the medulla region of the brain called respiratory rhythm center is primarily responsible for the regulation of respiration. II. A Chemosensitive area is situated adjacent to the rhythm which is highly sensitive to O_2,CO_2 and hydrogen ions . III . Receptors associated with aortic arch and carotid artery also can recognize changes in CO_2 and H^+ concentration and send necessary signals to the rhythm center for remedial actions. IV The neural signal from the pneumatic center can increase the duration of inspiration and thereby alter the respiratory rate .

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. Name two main acids present in acid rain. From where do these acids come in acid rain ?
