An experiment that is only one variable that has changed is a controlled variable experiment.

the independent/controlled variable

is a variable that can be changed according to the purpose of the experiment

<h3><em>Further explanation </em></h3>

The development of chemistry begins with experiments that consist of chemical stages/processes. This method is a form of the scientific method that is commonly used by scientists in carrying out experiments.

Several experiments, trials, and errors will be carried out to test the hypothesis until the expected results are in the predetermined problem at the outset.

Variables, which can be determined in 2:

  • 1. independent variable

, which is a variable that can be changed according to the purpose of the experiment

  • 2. fixed variable, i.e. variable whose value is constant and observed to determine changes in independent variables

We can control independent variables according to the results of the experiments to find conditions that have the most optimal results so that the goals of the problems that have been set will be achieved.

The continuous investigation is so that the control variables are not out of the problem boundary

So the right choice is a controlled variable

Answer;

D. controlled

An experiment in which only one variable is changed is a controlled experiment.

Explanation;

-A control experiment is an experiment where the researcher only changes one variable at a time in order to isolate the results.

In a controlled experiment, most conditions are constrained so that they do not change. One or two other conditions are then changed and measured by the experimenter. These are known as the independent variables.

For example; An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation.

Planets are classified in yhe domain _____<br>A. archaea<br>B. bacteria <br>C. eukarya​
Gelneren [198K]

Archaea means ancient, bacteria are, well, minuscule organisms that live everywhere, and eukarya are organisms with cells that have a nucleus as well as membrane-bound organelles... my best guess if it is planets you mean, then the answer would be archaea, if it is plants, like flowers or such, then it is eukarya.

I hope this helps!
