List three major forms in which CO2 is transported in our blood. Explain briefy the mechanism of CO2 transport in dissolved state. |
|
Answer» Carbon dioxide is transported as carbonic acid, as carbamino- haemoglobin and as bicarbonates. In tissues, about 7% of CO2 is carried in dissolved state through plasma. Carbon dioxide combines with water to form carbonic acid and is carried to lungs. This reaction mainly occurs in RBCs as it is catalysed by zinc-activated enzyme, carbonic anhydrase. Carbonic anhydrase is a zinc enzyme that speeds up the formation of carbonic acid. CO2 + H O→ H2 CO3 (Carbonic acid) Since the process of forming carbonic acid is slow, only a small amount of carbon dioxide is carried this way. |

Briefly describe the transport of CO2 in the blood. |
|
Answer» (i) As carbaminohaemoglobin (ii) CO2 combines with H2O in the presence of carbonic anhydrase to form H2CO3. H2CO3 dissociates to form H+ + HCO3–. At the tissue site, where pCO2 is high due to catabolism, CO2 diffuses into blood and stores HCO3– and H+. At the alveolar site, where pCO2 is low, formation of CO2 and H2O takes place. Thus CO2 trapped as HCO3 – at the tissue level and transported to the alveoli is released as CO2. |

Evolution and classification of organisms are interlinked. Give reasons to justify this statement |
|
Answer» Every organism has an inbuilt tendency for genetic variation which plays an important role in the origin of new species and forms the basis for evolution. The more characteristics two species have in common, the more closely they are related. Classification of organisms involves organising them in different groups, based on the similarities and dissimilarities of characteristics. Therefore, classification of species is a reflection of their evolutionary relationship. Thus, we can say that evolution and classification of organisms are interlinked |

“Evolution and classification of organisms are interlinked.” Give reasons to justify this statement. |
|
Answer» Evolution and classification of organisms are interlinked because of following reasons. █ Different life forms have evolved during the course of evolution. Classification deals with the grouping of these life forms into groups and sub groups based on similarities and differences. █ The more characteristics any two species have in common, more closely they are related. Thus, classification helps in tracing the evolutionary relationship between the two organisms. Hence, evolution and classification are interlinked. |

Read the passage given below carefully and answer the questions that follow : 1.The sage of science, “Einstein, was sitting in a depressive and pensive mood one evening. His eyes were brimming with tears. The pain was evident of his face. He peeped out of the window of his room. The sun had set a few minutes back. The sky was filled with a reddish glow. At this sunset, he felt that it was humanity that had sunk into devilish darkness and the reddish glow in the sky was the blood of humanity spilling all over the sky from earth. With tired steps, he walked back to his chair and settled down. It was the 9th of August 1945. Three days back, he had felt the same agony as if someone had torn him apart. He was deeply hurt and depressed when the heard on the radio that America had dropped an atom bomb on the Japanese city, Hiroshima. Today, within three days another bomb was dropped on another city, Nagasaki and lakhs of people had been killed. 2. He had heard that the blast released so much energy that it had paled all past destructions in comparison and death had played out a pitiable dance of destruction. The flames that broke out of the bomb were burning, melting and exploding buildings. Scared of the heat of the bomb, people had jumped into lakes and rivers, but the water was boiling and the people too were burnt and killed. The animals in the water were already boiled to death. Animals, trees, herbs, fragrant flowering plants were all turned into ashes. The atomic energy destruction had just not stopped there. It had entered the atmosphere there and had spread radiation that would affect people for generation to come and would also bring about destructive irreversible biological changes in animals and plants. 3. As the news of the atomic attack reached Einstein, and he became aware of the glaring horror of the abuse of atomic energy, his distress and restlessness knew no bounds. He could not control himself and picked up his violin to turn his mind on the other things. While playing the violin, he tried to dissolve in its sad notes, but couldn’t. He was burning on the embers of destruction; his heart was filled with an ocean of agony and tears just continued streaming uncontrollably out of his eyes. Night had fallen. His daughter came up and asked him to eat something as he had not taken anything for the last four days. His voice was restrained and he said, “don’t feel like eating.” 4. He could not sleep that night. Lying down, he was thinking how he had drawn the attention of the then American President Roosevelt towards the destructive powers of an atomic bomb. He had thought that this would be used to scare Hitler and put an end to the barbarism that. However, Roosevelt kept him in the dark and made false promises. Eventually, he had abused Einstein’s equation of E= mc2 that resulted in the destructive experiments. His actions had made science and scientists as murderers. Einstein kept on thinking for a long time. Eventually, he slipped into sleep. When he woke up at dawn, there was a new dawn in him too. The atomic threat had transformed his heart. 5. The next day, he decided to disassociate himself from the scientific policy of the government and all governmental institutions. He decided to open educational institutions for children, adolescents and youth – institutions where along with science, spirituality will be compulsorily taught. 6. To inaugurate this institution, he had invited two great philosophers, Bertrand Russell and Albert Schweitzer. Ten other great scientists who had won Nobel Prizes in different fields were also invited. They all saw a different Einstein, not a great scientist but a sage in him. The institution was opened by garlanding a photo of Mahatma Gandhi. While garlanding the Mahatma, he became emotional and said with a lump in his throat, “ I bow down to the great man who fought for the independence of his country through non – violence. He could do so because he was a truthful man and true spiritualist.” 7. Those who teach science should be taught spirituality too. Without harmony between science and spirituality, the destruction would continue unabated. A few years after this institution was built, a Japanese delegation came to meet him. Einstein broke down in the meeting and said, “You can give me any punishment and I will accept it . Anyway, I have decided to lead my life in penitence.” The Japanese were moved by his sincerity and forgot their grief.On the basis of your understanding of the above passage, answer each of the questions given below by choosing the most appropriate option :(a) Besides two great philosophers how many other scientists were invited by Einstein to inaugurate the institution where spirituality would be compulsorily taught ? (i) Five (ii) Ten (iii) Eight (iv) Fifteen (b) Which musical instrument did Einstein play when he was in grief? (i) Harmonium (ii) Guitar (iii) Violin (iv) Flute (c) Einstein came to know that America had dropped an atom bomb on the Japanese city, Hiroshima through (i) television. (ii) newspaper. (iii) radio. (iv) a telephonic message. (d) Which American President was told about the destructive power of an atomic bomb? (i) Kennedy (ii) Bill Clinton (iii) Lincoln (iv) Roosevelt (e) Einstein said to the Japanese delegation, (i) “You can give me any punishment and I will accept it.” (ii) “I am not at fault.” (iii) “What could I do (iv) “The President didn’t agree to my advice.” |

Give reasons for the following: (a) Transition elements and their compounds act as catalysts. (b) E° value for (Mn2+ |Mn) is negative whereas for (Cu2+ |Cu) is positive. (c) Actinoids show irregularities in their electronic configuration. |
|
Answer» (a) The catalytic properties of transition metals are attributed to their ability to exist in multiple oxidation states and form complexes. Variable oxidation states make them more efficient catalysts. (b) The electronic configuration of Mn2+ is d5 which is more stable because of half-filled d-subshell. While Cu2+ with electronic configuration d9 becomes stable after accepting two electrons with configuration d10 s1 due to fully-filled d-orbital. (c) The elements Th (At. no. 90) to Lr (At. no. 103) are together known as actinoids. For the first four actinoids Th, Pa, U and Np, the difference between the energy levels of 5f and 6d orbitals is small. Thus, in these elements (or ions) electrons may occupy either 5d or 6f orbitals. |

||||||||||||
|
Answer» (i) (a) Binary Fission in Amoeba-In this method, the nucleus first divides amitotically into two, followed by the division of the cytoplasm. The cell finally splits into two daughter cells. So, from one Amoeba parent, two daughter amoebae are formed. (b) Budding in Hydra-ln Budding, a small part o{ the body of the parents grows out as a 'bud' which then detaches and becomes a new organism. Hydra reproduces by budding using the regenerative cells. A bud develops as an outgrowth in hydra due to repeated cell division at one specific site. When fully mature, the bud detaches itself from the parent body and develops into new independent individuals. (c) Regeneration in Planaria-In this method, small cut or broken parts of the organism's body grow or regenerate into separate individuals. Planaria can be cut into any number of pieces and each piece grows into a complete organism. (ii) Difference between sexual and asexual reproduction

Read the passage given below and answer the questions that follow: The stark observation made in the Economic Survey of 15-16 that “Indian agriculture, is in a way, a victim of its own past success - especially the green revolution”, shows the dark reality of the agriculture sector at present and the havoc that has been wreaked by the green revolution.The green revolution, which is often characterized by the introduction of high-yielding variety of seeds and fertilizers, undoubtedly increased the productivity of land considerably. But the growth in the productivity has been stagnant in recent years, resulting in a significant decline in the income of farmers. There have also been negative environmental effects in the form of depleting water table, emission of greenhouse gases, and the contamination of surface and ground water. Needless to say, the agriculture sector is in a state of distress, which is severely affecting peasants and marginal farmers, and urgent policy interventions are required to protect their interests.The government has responded to the problem by constituting a panel, which will recommend ways to double the income of farmers by 2022. While this may be an overtly ambitious target, if we want to boost stagnated agricultural growth a shift has to be made, from food security of the nation to income security of the farmers. However, there are many hurdles that have to be crossed if we want to achieve this objective.The first major barrier to overcome is declining productivity. Data from 2013 reveals that India's average yield of cereal per hectare is far less than that of many countries (including several low income countries), but the difference is huge when compared to China. For instance, our average yield per hectare is 39% below than that of China and for rice this figure is 46%. Even Bangladesh, Vietnam and Indonesia fare better than India in case of rice yield. Further, there is a huge inter-regional variation; the wheat and rice yield from Haryana and Punjab is much higher than from the other states.In order to cross the declining productivity barrier there is a need to herald a rainbow revolution by making a shift from wheat-rice cycle to other cereals and pulses. Since wheat and rice coupled with other crops are backed by minimum support prices (MSP) and input subsidy (whether water, fertilizer or power) regime, there is a huge incentive for the farmers in the irrigated region of Northwest India to grow these crops.On the basis of your understanding of the above passage, answer the following questions very briefly: (a) What was revealed by the observations made in Economic Survey 15-16? (b) What does Green revolution mean?(c) Mention the ill effects of Green Revolution on our environment.(d) How can the stagnant agricultural growth be boosted? (e) Name the major problem that needs to be solved.(f) What would be the advantage of Rainbow Revolution?Choose the meanings of the words given below from the given options:(i) Wreaked(a) Cause damage(b) Solved(c) Neglected(d) Failed (ii) Stagnant(a) Slow(b) Steady(c) Motionless(d) Fast(iii) Distress(a) Contentment(b) Extreme sorrow(c) Satisfaction(d) Joy(iv) Herald(a) Signal of something to happen(b) Investigate(c) Halt(d) Hint |
