9 Dr. Garcia is performing an experiment to see how cell division in flies is affected by the addition of a certain protein, called protein W, into a cell's cytoplasm. She has found that adding protein W to a cell drastically reduces the chances of the cell becoming cancerous. For protein W to be developed into a cancer treatment, what comparison should she make?

The fly cells must be compared with human cells

Explanation:

Dr. Gracia's aim is the development of a potential cancer treatment. Remember that the treatment is meant for human beings.

Usually, the pre-clinical trials of the treatment is carried out on other organisms and the success rate is evaluated before trial on humans.

If protein W has been effective on flies, its effect on human cells should also be diligently compared before conclusions are drawn regarding the therapeutic effects of protein W.
