The student is conducting a nutrition experiment using lab rats. One group (control group) is fed a normal diet, while the other group (experimental group) is fed a diet high in protein. There were 30 rats total used in the experiment. At the end of the experiment, the average mass (weight) of a rat in the control group was 60.4 g while the average mass (weight) of a rat in the experimental group was 0.0689 kg. What is the average difference in weight between the two groups in grams?

8.5 g

Explanation:

Average weight of rats in the control group = 60.4 g

Average weight of rats in the experimental group = 0.0689 kg

0.0689 kg = 0.0689 x 1000 g

                       = 68.9 g

Average difference in weight between control and experimental group = Average weight of rats in experimental group - average weight of rats in control group

               = (68.9 - 60.4) g

                         = 8.5 g

Therefore, the average difference in weight between the two groups in grams is 8.5.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.
