1.	Do samples provide better results than the surveys? Give reason for your answer.
Answer» Yes, samples survey provide better results than census. A sample refers to a group or section of the population from which information is to be obtained. A good sample is generally smaller than the population and is capable of providing ‘ reasonably accurate information about the population at a much lower cost and shorter time. Suppose you want to study the average income of people in a particular state, according to the census method, we need to find out the income of every individual in the region, add them up and divide by number of individuals to get the average income of people in the state. This method would require huge expenditure, as a large number of investigators are to be employed. Alternatively, if a representative sample of few individuals is selected from the state to find their income, it saves time, money and energy in the process of determination of income. To sum up, sampling is considered a better method due to following reasons: It is more economical than the other techniques of collection of data. Sample investigation can be done at a greater speed as it consumes less time. When sampling is conducted scientifically and carefully, it gives accuracy. Planning, organization and supervision can be conveniently managed which leads to administrative convenience.

35.	In which way have microbes played a major role in controlling diseases caused by harmful bacteria?
Answer» Several micro-organisms are used for preparing medicines. Antibiotics are medicines produced by certain micro-organisms to kill other disease-causing micro-organisms. These medicines are commonly obtained from bacteria and fungi. They either kill or stop the growth of disease-causing micro-organisms. Streptomycin, tetracycline, and penicillin are common antibiotics. Penicillium notatum produces chemical penicillin, which checks the growth of staphylococci bacteria in the body. Antibiotics are designed to destroy bacteria by weakening their cell walls. As a result of this weakening, certain immune cells such as the white blood cells enter the bacterial cell and cause cell lysis. Cell lysis is the process of destroying cells such as blood cells and bacteria.
