Explain the difference between independent variables, dependent variables, and control variables.

Answer:

Independent: Purposely altered

Dependent: Changes with respect to the independent being altered

Controlled: Never changes

Explanation:

An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.

A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.

A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.

laboratory?
A. Test tubes
C. Perti dishes
B. Microscopes
D. Beakers​

Bacteria are sensitive to certain antibiotics like chloramphenicol and streptomycin, which kill the bacteria by interfering with translation through mechanisms that affect the ribosome's ability to function. If a researcher were to culture populations of Archaea and then treat them with either of the previously mentioned antibiotics, what would be the predicted results
