The first four of these are the most important, as they are used to construct the molecules that are necessary to make up living cells. They are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. In biology, the elements of life are the essential building blocks that make up living things. So the answer is B because by waiting them out underneath the *** is the first step to doing a colony count, and that'll give us not the number of all cells, but the number of colony forming units. So the best way to give up is to do colonie County. And the problem with this for is if we do a direct so direct counts would not be just living cells would include dead cells and we only want can be living. The state needs 10-7 to look at doing a direct microscopic. We can't use direct microscopic count because of the concentration is too low. So if we want to do a direct counts we could use A um counting chamber. So what we're looking at first of all is which of these methods will work? Which of these methods would be the best. Should we use a counting chamber? Place out an appropriate solution onto the front leg to do a colony camp. We have a simple of broth with eco lion, we want to detect the precise number of living sounds.
