During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the a. manipulated variable. b. responding variable. c. hypothetical variable. d. dependent variable.

Option a (manipulated variable) would be the appropriate choice.

Explanation:

To analyze the influence on something like a dependent variable, another modified variable seems to be an important variable responsive to modifications in quite an analysis. Plainly defined, the variable has been adjusted to determine its effect on the overall outcome of the study. There would be only one manipulated component in a correctly planned analysis.

The other options offered are not relevant to the situation described. So, the solution above is the best one.

A) 4 amusingb)alpha particle is a helium nucleus. it contains 2 protons and 2 neutrons.c)alpha particle has charge of +2.
