In a measurement of quantum efficiency of photosynthesis in plants it was found that 10 quanta of red light of wavelength 6850 A^@ were needed to release one molecule of O_2 the average energy storage in this process is 112 kcal/mol of O_2 evolved.What is the energy conversion efficiency in this experiment?Given=1 cal=4.18J: N_A=6xx10^23 mol^-1 , h=6.63xx10^-34 Js

Two persons A and B get together once a weak to play a game. They always play 4 games . From past experience Mr. A wins 2 of the 4 games just as often as he wins 3 of the 4 games. If Mr. A does not always wins or always loose, then the probability that Mr. A wins any one game is (Given the probability of A's wining a game is a non-zero constant less than one).

In an experiment done by Griffith it was found that when virulent capsulated smooth 'S' bacteria were injected into healthy mice, the mice dies of pneunomia. When mice were injected with non virulent 'R' forms of same bacteria, they survived and did not die to pneumonia. in another case when S-forms were killed by heating at above 60^(@)C and injected, rats did not get pneumonia, but when killed, s-forms and R-forms of bacteria were mixed and injected, the rats suffered from pneumonia and died. which one of the following conclusions can be drawn from the above experiment?
