Question : What happens if the egg is not fertilised in woman ? |
|
Answer» Solution :Menstruation is the periodic event taking place after every 28 days in mature woman. This is a CYCLIC process, interrupted only by pregnancy. During menstruation there is bleeding through vaginal opening. The cell debris and unfertilised ovum is given out of the body during menstruation. If the egg is not fertilised, it lives for about one day. Since the ovary releases one egg every month, the uterus ALSO prepares itself every month to receive a fertilised egg. Uterine lining becomes thick, spongy and richly supplied with blood. But if fertilisation does not occur then this lining is not needed any longer. So, the lining slowly breaks and comes out through the vaginal opening as blood and MUCOUS. This cycle TAKES place roughly every month and is called menstruation. It usually lasts for about two to eight days.

This leading to the LOSS of local people control over the local water resources in India. |

Question : What evidence do we have for the origin of life from inanimate matter? |
|
Answer» Solution :J.B.S. Haldane, a British scientist (who became a citizen of India later), suggested in 1929 that LIFE must have developed from the simple inorganic molecules which were present on earth soon after it was formed. An experiment was conducted by Stanley L. Miller and Harold C. Urey in 1953. They created an atmosphere similar to that was thought to exist on early earth (this had molecules like AMMONIA, methane and hydrogen sulphide, but no oxygen) over water. This was maintained at a temperature just below `100^@C` and sparks were passed through the mixture of gases to SIMULATE lightning. At the end of a week, 15% of the carbon (from methane) had been converted to simple compounds of carbon INCLUDING amino acids which make up protein molecules. |

Question : What do you understand by artificial kidney ? Name the principle on which it works. |
Answer» Solution :Artificial Kidney. In case of acute kidney failure, the poisonous materials may accumulate in the body fluids which CAUSE oedema and finally lead to death of the patient. In such cases, artificial kidney is used. It works on the principle of dialysis and separates wastes from the blood. The process is called haemodialysis.Artificial kidney contains a number of tubes with a semipermeable lining. Its functioning is similar to kidney, but it is different since there is no reabsorption involved. In this, blood from an artery is diverted through a cellophane tube, having pores equal to those of glomerular capillaries, PLACED in a circulating bath. Concentration of bath-fluid is kept equal to that of normal plasma. The pores in the cellophane tube allow SMALL-sized wastes like urea, ammonium salts etc. to PASS through but do not allow the passage of blood cells, proteins, fats etc. Diffusion of small and USEFUL substances like glucose, amino acids etc. is prevented by keeping their concentration in the dialysis fluid equal to the normal plasma. Blood from dialyser is returned to the body through a vein.

Question : What is parthenogenesis ? Give example. |
|
Answer» Solution :(1) PARTHENOGENESIS is an asexual REPRODUCTION in which unfertilized eggs develop into offsprings. (2) In this process generally egg develops into new individual WITHOUT meiosis and fertilization . So the offsprings are diploid. (3) In some species of animals reproduction occurs only through parthenogenesis. There are no males known in these species . Ex : Rotifers. (4) In another type of parthenogenesis meiosis does occur and the egg can develop whether fertilized or not . (5) The monoploid offsprings develop into males and diploid into females. Ex : Bees, Ants, WASPS. (6) Nowadays we are able to develpo seed less FRUITS like matermelon, graps,Pomegranate etc. |
