Answer 1

hypothesis is A hypothesis (plural hypotheses) is a precise, testable statement of what the researcher(s) predict will be the outcome of the study.

Step-by-step explanation:

independent variable is what u can change

dependent variable is the one u can measure

control variable is one u keep the same

control treatment In the design of experiments, treatments are applied to experimental units in a treatment group. In comparative experiments, members of a control group receive a standard treatment, a placebo, or no treatment at all. There may be more than one treatment group, more than one control group, or both

experimental treatment in research, the conditions applied to one or more groups that are expected to cause change in some outcome or dependent variable.
