A scientist conducted an investigation about the effects of diet on disease resistance in rats and made surprising observations. The mice with a genetic ear mutation seemed to show similar patterns of resistance compared to mice with normal ears. Based on this information, what will most likely occur? She will perform a second investigation on the role of certain genes in disease resistance. She will revise her hypothesis to pertain to mutations rather than diet, and update her data accordingly. She will use this information to determine that her original question was nonscientific, so she will revise it. She will determine that her hypothesis was invalid because resistance must be genetic.

Cells, Tissues and Organs. As we mentioned before, cells are the building blocks of life. When we have a group of similar cells working together this is called a tissue, for example muscle tissue is made up of lots of muscle cells. All the cells in a tissue look the same and perform the same job.

The correct answer for your question is option (A) - She will perform a second investigation on the role of certain genes in disease resistance.
According to the above information, the scientist have already made a conclusion that the mice with ear mutation is also showing the same set of disease resistance like the mice with no ear mutation. So the scientist must have to look for another set of results to conclude what type of gene is responsible for the disease resistant character of the mice. Hence she wanted to perform another set of investigation on the role of certain gene that responsible for the disease resistance.
