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 .

Assertion :- Strong pneumotoxic signal results complete filling of lungs. Reason :- Strong pneumotaxic singla increases the duration of inspiration as well as expiration.

Identify the correct terms for the given statements and select the correct answer. (i) Sudden increase in the rate of respiration during ripening of fruits. (ii) Reduction in the consumption of respiratory substrate when mole of respiration is changed from anaerobic to aerobic. (iii) Respiratory oxidation of carbohydrates and fats.

Fill up the blanks in the following paragraph by selecting the correct option. Human beings have a significant ability to maintain and moderate the respiratory rhythm to suti the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called overset((i))"_______" is primarily responsible for this regulation. Another centre present in the pons region of the brain called overset((ii))"_______" can moderate the functions of the repiratory rhytm cenre. Neutral signal from this cenre cen reduce the duration of overset((iii))"_______" and thereby alter the respiratory rate. A overset((iv))"_______" is situated adjacent to the rhythm centre which is highly sensitive to CO_(2) and hydrogen ions.

Assertion If angle of incidence in case of a prism is gradually increased, then deviation produced by prism will first decrease, then increase. Reason At minimum deviation, r_(1) =A/2 .
