MCQ-> Rearrange the following six sentence (1), (2), (3), (4), (5) and (6) in the proper sequence to form a meaningful paragraph ; then answer the questions given below them. A. There are a number of items in the atomic energy programme which are being made indigenously. B. Given the overall energy situation in India, the use of nuclear power in some measure is inescapable even while thermal and hydrogen power continue to be the dominant elements. C. However. commercial aspects of exploiting nuclear capabilities, especially for power-generation programmes, have been recently given high priority. D. Atomic energy programmes have been subject to serve restrictions for very obvious reasons as the Department of Atomic Energy is becoming self-reliant in areas in which only a few countries have such capability. E. Even to meet these nuclear power requirements, India critically requires a commercial level power-generation capability with its commensurate safety and nuclear waste management arrangements F. Thus, in the Indian context energy security is also crucial, perhaps much more than it is for the U.S.A. because India imports a good part of its crude oil requirements, paying for it with precious foreign exchange.Which of the following will be the FIFTH sentence after rearrangement ?

MCQ-> The membrane-bound nucleus is the most prominent feature of the eukaryotic cell. Schleiden and Schwann, when setting forth the cell doctrine in the 1830s, considered that it had a central role in growth and development. Their belief has been fully supported even though they had only vague notions as to what that role might be, and how the role was to be expressed in some cellular action. The membraneless nuclear area of the prokaryotic cell, with its tangle of fine threads, is now known to play a similar role.Some cells, like the sieve tubes of vascular plants and the red blood cells of mammals, do not possess nuclei during the greater part of their existence, although they had nuclei when in a less differentiated state. Such cells can no longer divide and their life span is limited Other cells are regularly multinucleate. Some, like the cells of striated muscles or the latex vessels of higher plants, become so through cell fusion. Some, like the unicellular protozoan paramecium, are normally binucleate, one of the nuclei serving as a source of hereditary information for the next generation, the other governing the day-to-day metabolic activities of the cell. Still other organisms, such as some fungi, are multinucleate because cross walls, dividing the mycelium into specific cells, are absent or irregularly present. The uninucleate situation, however, is typical for the vast majority of cells, and it would appear that this is the most efficient and most economical manner of partitioning living substance into manageable units. This point of view is given credence not only by the prevalence of uninucleate cells, but because for each kind of cell there is a ratio maintained between the volume of the nucleus and that of the cytoplasm. If we think of the nucleus as the control centre of the cell, this would suggest that for a given kind of cell performing a given kind of work, one nucleus can ‘take care of’ a specific volume of cytoplasm and keep it in functioning order. In terms of material and energy, this must mean providing the kind of information needed to keep flow of materials and energy moving at the correct rate and in the proper channels. With the multitude of enzymes in the cell, materials and energy can of course be channelled in a multitude of ways; it is the function of some information molecules to make channels of use more preferred than others at any given time. How this regulatory control is exercised is not entirely clear.The nucleus is generally a rounded body. In plant cells, however, where the centre of the cell is often occupied by a large vacuole, the nucleus may be pushed against the cell wall, causing it to assume a lens shape. In some white blood cells, such as polymorphonucleated leukocytes, and in cells of the spinning gland of some insects and spiders, the nucleus is very much lobed The reason for this is not clear, but it may relate to the fact that for a given volume of nucleus, a lobate form provides a much greater surface area for nuclear-cytoplasmic exchanges, possibly affecting both the rate and the amount of metabolic reactions. The nucleus, whatever its shape, is segregated from the cytoplasm by a double membrane, the nuclear envelope, with the two membranes separated from each other by a perinuclear space of varying width. The envelope is absent only during the time of cell division, and then just for a brief period The outer membrane is often continuous with the membranes of the endoplasmic reticulum, a possible retention of an earlier relationship, since the envelope, at least in part, is formed at the end cell division by coalescing fragments of the endoplasmic reticulum. The cytoplasmic side of the nucleus is frequently coated with ribosomes, another fact that stresses the similarity and relation of the nuclear envelope to the endoplasmic reticulum. The inner membrane seems to posses a crystalline layer where it abuts the nucleoplasm, but its function remains to be determined.Everything that passes between the cytoplasm and the nucleus in the eukaryotic cell must transverse the nuclear envelope. This includes some fairly large molecules as well as bodies such as ribosomes, which measure about 25 mm in diameter. Some passageway is, therefore, obviously necessary since there is no indication of dissolution of the nuclear envelope in order to make such movement possible. The nuclear pores appear to be reasonable candidates for such passageways. In plant cells these are irregularly, rather sparsely distributed over the surface of the nucleus, but in the amphibian oocyte, for example, the pores are numerous, regularly arranged, and octagonal and are formed by the fusion of the outer and inner membrane.Which of the following kinds of cells never have a nuclei?

MCQ-> Thought the Cold War has ended selective tactics are still continuing for ensuring the military and economic dominance of developed countries Various types of technology denial regimes are still being enforced which are now being mainly targeted against developing countries like India Today we in India encounter twin problems On one side there is a large scale strengthening of our neighbours through supply of arms and clandestine support to their nuclear and missile programmes and on the other side all efforts are being made to weaken our indigenous technology growth through control regimes and dumping of low-tech system accompanied with high commercial pitch in critical areas Growth of indigenous technology and self-reliance are the only answer to the problem Thus in the environment around India the number of missiles and nuclear powers are continuously increasing and destructive weapons continue to pile up around us in spite of arms reduction treaties To understand the implications of various types of warfare that may affect us we need to take a quick look at the evolution of war weaponry and the types of warfare I am highlighting this point for the reason that in less than a century we could see change in the nature of warfare and its effects of society In early years of human history it was mostly direct human warfare During the twentieth century up to about 1990 the warfare was weapon driven The weapons used were guns tanks aircraft ships submarines and the nuclear weapons deployed on land/sea/air and also reconnaissance spacecraft. Proliferation of conventional nuclear and biological weapons was at a peak owing to the competition between the superpowers The next phase in a new form has just started from 1990 onwards The world has graduated into economic warfare.The means used is control of market forces through high technology.The participating nations apart from the USA, are Japan the UK France Germany certain South East Asian countries and a few others The driving force is the generation of wealth with certain types of economic doctrine The urgent issue we need to address collectively as a nation is how do we handle the tactics of economic and military dominance in this new form coming from the backdoor ? Today technology is the main driver of economic development at the national level Therefore we have to develop indigenous technologies to enhance our competitive edge and to generate national wealth in all segments of economy Therefore the need of the hour is arm India with technology.Why do certain countries use selective tactics against developing countries ?
