Question

part b - evaluating experimental design. excited about the fungus chemicals promise for treating cancer, you write up your experimental results and send the paper to a prestigious scientific journal, hoping it will be published. the journal sends your paper out to several scientists for evaluation - a process known as peer review. the reviewers identify several issues with the experimental design and data presented in your paper. which of the following criticisms are valid issues of concern that peer reviewers might identify? select all that apply. the treatment kills cancer cells, but it might simply be a poison that kills all cells - even normal cells. cell samples were taken from too few patients. the effect may not be real because we dont know if the results are reproducible. there was no control in the experiment. the experiment should have been run for more days in order to make the effect of the fungus chemical clearer. incorrect; try again; 4 attempts remaining. at least one of your answers is incorrect. review the data. does it show a clear effect during the course of the 10 - day experiment?

Explanation:

Lack of control, small sample size, uncertainty of effect and possibility of non - specific toxicity are valid concerns.

Answer:

The treatment kills cancer cells, but it might simply be a poison that kills all cells—even normal cells.; There was no control in the experiment.; The effect may not be real because we don’t know if the results are reproducible.; Cell samples were taken from too few patients.; The experiment should have been run for more days in order to make the effect of the fungus chemical clearer.
