In experimental design, this is a comparison group of research participants who, when the independent variable is manipulated, are not exposed to the treatment that subjects in the experimental group are exposed to, but
who in other respects are treated identically to the experimental group, to provide a baseline against which to
evaluate effects of the treatment.

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
