First scientist to find out amino acid sequence of a protein was

A road tanker carrying an acid was involved in an accident and its contents spilled on the road. At the side of the road, iron drain covers began melting and fizzing as the acid ran over them. A specialist was celled to se if the acid actually leaked into the nearby river. (a) Explain how the specialist could carry out a simple test to see if the river water contains some acid or not. (b) The word 'melting' is incorrectly used in the report. Suggest a better name that should have been used for the same purpose. (c) Explain why the drain covers began fizzing as the acid ran over them.

There is a solution of p-hydroxybenzoic acid and p-amino benzonoc acid. Discuss one method by which we can separate them and also write down the confirmatory test of the functional group present.

Direction: Given below is a short passage. After the passage, you will find some items based on the passage. First, read a passage and answer the items based on it. The avowed purpose of the exact sciences is to establish complete intellectual control over experience in terms of precise rules which can be formally set out and empirically tested. Could that ideal be fully achieved, all truth and all error could henceforth be ascribed to an exact theory of the universe, while we who accept this theory would be relieved of any occasion for exercising our personal j udgement. We should only have to fo llow the rules faithfully. Classical mechanics approaches this ideal so closely that it is often thought to have achieved it. But this leaves out of account the element of personal judgement involved in applying. the formulae of mechanics to the facts of experience. An exact theory of the universe is

Directions (For the items which follow) : In the following items, each passage consists of six sentences. The first sentence (S_1) and the final sentence (S_6) are given in the beginning. The middle four sentences in each have been removed and jumbled up. These are labelled P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark accordingly on the. Answer Sheet. S_1 : In 1668 an important discovery was made. S_6 : That was the beginning of the end of the theory of spontaneous generation of higher plants and animals. P : He put some rotting meat and fish in open jars and watched them. Q : When he covered the jars with muslin, he found that flies came and laid their eggs on the muslin, but no maggots developed on the meat. R : In time, he noticed that flies came and laid their eggs in the meat and the maggots hatched from the eggs. S : An Italian physician named Redi decided to test the idea that worms were generated spontaneously in rotting meat. The proper sequence should be :
