Answer» All human beings have 23 pairs of chromosomes. Human males have 22 pairs of autosomes and contain one or two types of sex chromosome. They are either X or Y. On the contrary, human females have 22 pairs of autosomes and contain only the X sex chromosome. The sex of an individual is determined by the type of the male gamete (X or Y), which fuses with the X chromosome of the female. If the fertilizing sperm is X, then the baby will be a girl and if it is Y, then the baby will be a boy. |

What are the functions of the cytoskeleton? |
|
Answer» As the name indicates, the cytoskeleton is responsible for the support of the normal shape of the cell; it also acts as a facilitator for substance transport across the cell and for the movement of cellular organelles. For example, the sliding between actin-containing filaments and the protein myosin creates pseudopods. In cells of the phagocytic defence system, like macrophages, the cytoskeleton is responsible for the plasma membrane projections that engulf the external material to be interiorized and attacked by the cell. |

Describe the case for planning. |
|
Answer» The economic planning is justified on the following grounds. (i) To accelerate and strengthen market mechanism: The market mechanism works imperfectly in underdeveloped countries because of the ignorance and unfamiliarity with it. A large part of the economy comprises the nonmonetized sector. (ii) To remove unemployment: Capital being scarce and labour being abundant, the problem of providing gainful employment opportunities to an ever-increasing labour force is a difficult task. (iii) To achieve balanced development: In the absence of sufficient enterprise and initiative, the planning authority is the only institution for planning the balanced development of the economy.
(iv) To remove poverty and inequalities: Planning is the only path open to underdeveloped countries, for raising national and per capita income, reducing inequalities and poverty and increasing employment opportunities. |
