For each of the varieties of acid–base disturbance A–E, select the best option for a possible cause from the following list. 1. Sudden laryngeal obstruction. 2. Severe chronic respiratory disease. 3. Chronic renal failure. 4. Mountain climbing. 5. Severe diarrhoea. A. Uncompensated respiratory acidosis. B. Uncompensated metabolic acidosis. C. Compensated respiratory acidosis. D. Uncompensated respiratory alkalosis. E. Compensated metabolic acidosis. |
|
Answer» A. Option 1 Sudden laryngeal obstruction. The obstruction leads to a rapid rise in PCO2 before the kidneys can compensate by generating bicarbonate thus raising the blood bicarbonate level. B. Option 5 Severe diarrhoea. Severe diarrhoea results in loss of bicarbonate in the stools and thus to a fall in the blood bicarbonate level. C. Option 2 Severe chronic respiratory disease. The raised PCO2 in chronic respiratory disease may be compensated for by renal generation of bicarbonate to raise the blood bicarbonate level. D. Option 4 Mountain climbing. The respiratory drive caused by the action of low Po2 on arterial chemoreceptors washes out CO2. This lowers the PCO2 to cause an alkalosis. Eventually the kidneys compensate by eliminating more bicarbonate. E. Option 3 Chronic renal failure. The fall in blood bicarbonate used in buffering the acid residues of protein digestion in chronic renal failure is compensated for by an increased respiratory drive that results in a fall in PCO2. |

Other things remianing unchanged, when in a country the price of foreign currency rises, national income is : (choose the correct alternative)A. Likely to riseB. Likely to fallC. Likely to rise and fall bothD. Not affected |
|
Answer» Correct Answer - A When the prices of foreign currency rises, the national income is likely to rise. This is because rise in foreign prices will lead to increase in the one of the components of national income i.e. net exports. That is, exports will increase and imports will decrease (as imports have become expensive), this will ultimately lead to increase is national income. |

A consumer consumes only two good X and Y both priced at Rs.3 per unit. If the consumer chooses a combination of these two goods with Marginal Rate of Substitution equal to 3, is the consumer in equilibrium ? Give reasons. What will a rational consumer do in this situation ? Explain. OR A consumer consumes only two goods X and Y whose prices are Rs.4 and Rs.5 per unit respectively. If the consumer chooses a combination of the two goods with marginal utility of X equal to 5 and that of Y equal to 4, is the consumer in equilibrium? Give reason. What will a rational consumer do in this situation? Use utility analysis. |
|
Answer» At the point of consumer equilibrium the following equality should be met : `MRS=(P_(x))/(P_(y))` According to the question, MRS=3 `(P_(x))/(P_(y))=(3)/(3)=1` So, MRS is greater than the price ratio. Thus, to reach the equilibrium point a rational consumer would decrease the consumption of good y. OR According to the utility approach, a consumer reaches equilibrium where the following equality is met. `(MU_(x))/(P_(x))=(MU_(y))/(P_(y))` According to the given question, `(MU_(x))/(P_(x))=(5)/(4)` `(MU_(y))/(P_(y))=(4)/(5)` So, `(MU_(x))/(P_(x))` is greater than `(MU_(y))/(P_(y))`. Thus, to reach the equilibrium, a rational consumer would increase the consumption of good x and decrease that of good y. |
|

A consumer consumes only two good X and Y, both priced at Rs.2 per unit. If the consumer chooses a combination of the two goods with Marginal Rate of Substitution equal to 2, is the consumer in equilibrium? Why or why not? What will be rational consumer do in this situation? Explain. OR A consumer consumes only two goods X and Y whose prices are Rs.5 and Rs.4 respectively. If the consumer chooses a combination of the two goods with marginal utility of X equal to 4 and that of Y equal to 5, is the consumer in equilibrium? Why or why not? What will a rational consumer do in this situation? Use utility analysis. |
|
Answer» At the point of consumer equilibrium the following equality should be met : MRS=`(P_(x))/(P_(y))` According to the question, MRS=2 `(P_(x))/(P_(y))=(2)/(2)=1` So, MRS is greater than the price ratio. Thus, to reach the equilibrium point a rational consumer would decrease the consumption of good y. OR According to the utility approach, a consumer reaches equilibrium where the following equality is met. `(MU_(x))/(P_(x))=(MU_(y))/(P_(y))` According to the given question `(MU_(x))/(P_(x))=(4)/(5)` `(MU_(y))/(P_(y))=(5)/(4)` So, `(MU_(y))/(P_(y))` is greater than `(MU_(x))/(P_(x))`. Thus, to reach the equilibrium, a rational consumer would increase the consumption of good y and decrease that of good x. |

Summarize the freedom struggle and nationalist movement of India.OR Outline the role of any two famous leaders of India in the freedom movement |
|
Answer» It has been observed that the struggles for Freedom in India had been a merger of a series of Political, Socio-Cultural, and Economic factors that led to the rise of Nationalism. The Nationalist Movements in India were early popular movements seeking independence of India from Great Britain. Although actions such as the Salt March in 1930 raised pressure on the colonialist administration and won concessions, these remained limited in scope and fell short of the complete independence sought. The Swadeshi movement encouraged the Indian people to stop using British products and start using their own handmade products. The original Swadeshi movement emanated from the partition of Bengal in 1905 and continued up to 1908. The Swadeshi movement which was a part of the Indian freedom struggle was a successful economic strategy to remove the British empire and improve economic conditions in India. The Swadeshi movement soon stimulated local enterprise in many areas. After Lord Curzon announced the partition of Bengal in 1905, there was massive opposition from the people of Bengal. Initially, the partition plan was opposed through press campaign. The total follower of such techniques led to the boycott of British goods. The British swiftly responded to the Quit India Movement with mass detentions. Over 100,000 arrests were made, mass fines were levied and demonstrators were subjected to public flogging. Hundreds of civilians were killed in violence many shot by the police army. The Quit India Movement turned out to be not very successful and only lasted until 1943. OR Bal GangadharTilak- Bal GangadharTilak was born on 22 July 1856, in a middle class family in Ratnagiri, a small coastal town in southwestern Maharashtra. His father, GangadharShastri, was a noted Sanskrit scholar and school teacher at Ratnagiri. Tilak was a brilliant student and also very good in mathematics. Since his childhood, Tilak had an intolerant attitude towards injustice and he was truthful and straight forward in nature. After graduating from Deccan College, Pune in 1877, Tilak cleared the LLB from the Elphinston College, Mumbai. Later, he helped found a school that laid emphasis on nationalism. Mohandas Karamchand Gandhi- Mohandas Karamchand Gandhi was born on 02 October 1869 at Porbandar which is in the present day Gujarat. His father, Karamchand Gandhi, was a Dewan or Prime Minister of Porbandar. His mother, Putlibai, was a very religious lady and left a deep impression on Gandhi's mind. He was a mediocre student and was excessively shy and timid. He married at the age of thirteen to Kasturbai. Later on in his life, Gandhi denounced the custom of child marriage and termed it as cruel. After schooling, he joined the Samaldas College in Bhavnagar. |
