1)"A control is important for an experiment because it allows the experiment to minimize the changes in all other variables except the one being tested"

2) "The main ways that scientists communicate research results is by publishing the results in journals. Journals are archived and can be read by other people in the future"

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
