When proofing (or dissolving) yeast, it takes about 5 to 10 minutes. The time varies depending on the freshness of the yeast, as well as the amount used. It also depends on the method used in dissolving the yeast, so in some recipes, it can take considerably longer for the yeast to dissolve.
Dissolve, yes; activate and reproduce, no. Alcohol is a waste product of yeast, and so it has no benefit to the yeast. Yeast feeds on sugars, so it needs carbohydrates (i.e., flour, sugar, fruit) to achieve the desired results, be they gas production for the leavening of bread, or the production of alcohol.
Cavemen do not dissolve.
No because you dissolve the yeast in water.

There is no such thing as a lipo. Lipo-dissolve is a procedure that dissolves the fat cells in ones body. It is reported that it will take multiple injections to dissolve any fat.
Your recipe should indicate where and how to add the yeast, but yeast does not dissolve well in milk (if at all). Yeast forms into large clumps when mixed directly with milk and will take much longer to activate. I made this mistake the first time I tried to substitute milk for water when making bread. The usual way of adding yeast to such a recipe is to fully dissolve the yeast in 1/4 cup of warm water (about 110 degrees Fahrenheit). If the water is not warm enough, it won't activate the yeast and if it's too warm, it can kill the yeast. One of my colleagues proofs the yeast in the usual way (1/4 cup warm water, 1 tsp sugar, 1 tsp yeast), then adds the rest of the yeast to the water, mixes the dry ingredients with the milk for the recipe, then adds the water-yeast mixture to that. He claims that it works perfectly. Of course, if you use 1/4 cup of water to dissolve your yeast, subtract 1/4 cup of milk from the recipe unless otherwise indicated. And also make sure you're using the proper yeast for whatever it is you are baking.
