		| Find the change in internal energy for system
                                        : The air in an inflated balloon (defined as the system) is warmed over a toaster and absorbs 130J of heat. As it expands, it does 76kJ of work. What is the change in internal energy for the system? | 
		| Why does the dye wash out of the vegetative cells
                                        : even though endospore may be observed as a result of routine Simple or  Gram Staining , it is still necessary to perform the Schaeffer-Fulton  stain, Why ? | 
		| Null hypothesis-two tailed test
                                        : A manufacturer claims that the mean lifetime, mu, of its light bulbs is  44 months. The standard deviation of these lifetimes is 7 months.  Seventy bulbs are selected at random, and their mean lifetime is found  to be 43 months. |
