amazingly alike. Although they were born on the same day‚ they lived different lives. Edward grew up in a palace and Tom grew up in a small，dirty room in a narrow street． These two boys looked like two different kinds of people that would never meet in this world.

Conclusion: 1. Write at least ten questions that you would like answered about this experiment. 1. What is the identity of Crystal “X”‚ Liquid “Y”‚ and Liquid “Z”? 2. Why were the colors different when Crystal “X” was added to Liquid “Y”‚ but when they were mixed it turned from green to blue? 3. Why did the metal foil turn brownish red once added to Crystal “X” and Liquid “Y” solution? 4. Were Liquid “X” and Liquid “Y” the same liquid? 5.What chemical reaction happened that made vapor

similar pattern; however‚ spore-crystal complex formation of the indigenous Bt isolates was different with respect to the reference strain. The two indigenous isolates formed the maximum sporecrystal complex at 36 h‚ whereas the reference strain did the same at 66 h. Hence‚ the productivity of endotoxin formation of the indigenous isolates‚ 34.30 10-3 and 37.50 10-3 g/L/h respectively‚ were higher than that of the reference strain (21.37 10-3 g/L/h). Spore-crystal complex of the bacilli was recovered
