Ascientist is conducting an experiment to see which vitamin, brand x, y, or z, will mice gain weight. an equal amount of each vitamin will be mixed with mouse food and given to ten mice every day for ten days. at the end of ten days, all mice will be weighed. what would serve as a good control for this experiment?

The good control would be if a mouse or mice who have given food without vitamin for ten days.

Explanation:

The good control of an experiment must remain equal or the same throughout in order to receive precise or accurate results. It is something that is used as an ideal of comparison for checking the end results of an experiment.

A mouse who have given food without equal or no vitamin for ten days would be a good control as it will help in comparing the weight with the ten mice who were given an equal amount of vitamin for ten days.

Thus, good control would be if a mouse or mice who have given food without vitamins for ten days.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
