What advantage would there be for an organism to be able to turn on or off particular genes in response to certain conditions?

Gene regulation allows for adaptation to differing conditions and prevents wasteful overproduction of unneeded proteins. Good examples of highly regulatable genes are the enzymes which break down carbohydrate food sources. If the sugar arabinose is present in the growth medium it is beneficial for bacteria to produce the enzymes necessary to catabolize the sugar source. Conversely, if arabinose is not present in the nutrient media, it would be very energetically wasteful to produce the enzymes to break down arabinose.

Is perspiring a characteristics of life?
Perspiring is an example of one of the characteristics of life. "Response to Stimuli" is said characteristic. It is when an organism triggers a response to its surrounding environment or conditions.

How is the cause of an infectious disease established?
That is a very good question. When you find a bacteria at the place where you do not find the same normally and then you get particular symptom and sign complex. Then you can say that this disease is caused by that particular organism. So when you are able to culture the bacteria from say blood or urine, where that is not found normally. Secondly after the infection of particular microorganism if you get the heightened antibody response you can say that particular organism is involved in that particular disease. Next you can have a statistical evidence to say that particular organism is responsible to cause the disease. So when you find streptococci in say 5 % of healthy persons and say 50 % of sore throat patients, you can say that this organism is associated with the pharyngitis.
