Question : Taking little amount of alcohol is good to health. Do you agree with this statement? |
| Answer» Solution :Yes. The STATEMENT is true according to the medical practitioners. But the danger in it is that first of all they START it as a MEDICINE, after some days it will become a HABIT and the amount would increase. Then he would become addict to it. According to a proverb, "prevention is better than cure". So don.t use alcohol even if it is good for your health. | |

Question : Taking the example of Peppered moth, explain the action of natural selection. What do you call the above phenomenon ? |
| Answer» Solution :Natural selection can be EXPLAINED clearly through industrial melanism. Industrial melanism is a classical case of Natural selection exhibited by the peppered moth, Biston betularia. These were available in TWO colours, white and black. Before industrialization peppered moth both white and black coloured were common in England. Pre-industrialization witnessed white coloured background of the wall of the buildings hence the white coloured moths escaped from their predators. Post industrialization, the tree trunks became dark DUE to smoke and soot let out from the industries. The black moths camouflaged on the dark bark of the trees and the white moths were easily identified by their predators. Hence the dark coloured moth population was selected and their NUMBER increased when compared to the white moths. Nature offered POSITIVE selection pressure to the black coloured moths. The above proof shows that in a population, organisms that can adapt will survive and produce more progenies resulting in increase in population through natural selection | |

Question : Taking examples under each category, discuss upstream and downstream processing. |
|
Answer» Solution :Upstream processing : Biotechnological processes can be separated into upstream processes and downstream processes. The upstream process is defined as the entire process from DNA isolation and CULTURE expansion of the cells until final product is obtained. Downstream processing : After completion of the biosynthetic stage, the product has to be SUBJECTED through a series of processes before it Is ready for marketing as a final product. The processes INCLUDE separation and PURIFICATION, which are collectively referred to as downstream processing. The product must be formulated with suitable preservatives. Such formulation has to undergo through clinical trials as in case of DRUGS. Strict quality control testing for each product is also required. The downstream processing and quality control testing vary from product to product.

| 7179. |
Question : Taking examples under each category, discuss upstream and downstream processing, |
| Answer» Solution :Upstream processing is the start of microbial activity for an industrial process. It INCLUDES a proper nutrient solution, a PURE strain of desired microbe and optimum conditions of the nutrient solution like proper AERATION, temperature and optimum pH. Downstream processing is the process of obtaining the products of a microbial activity. When a sample DRAWN out from the culture medium INDICATES presence of optimum product in the cells or completion of biosynthetic phase, the biomass is removed and product is isolated. | |
