In an experiment, a researcher can make claims about causation
Yakvenalex [24]

Causation works on cause and effect, so the changed independent variable is the cause and the changed dependent variable is the effect.

An entomologist (bug scientist) wants to determine if temperature changes how many times a cricket chirps. What is the dependent
murzikaleks [220]

Answer:

Number of times a cricket chirps.

Explanation:

Let us use a graph to understand the function Here the entomologist wants to know the effect of temperature on the number of chirps of a cricket so, the chirps should vary with temperature. The opposite cannot be true i.e., the temperature is not dependent on the number of chirps rather the number of chirps are dependent on temperature.

So, the x axis will be represent the temperature and the y axis will represent the number of chirps.

Hence, the dependent variable will be number of times a cricket chirps i.e., the y axis.

steposvetlana [31]
C. This is the idea of "black body radiation". Charcoal/carbon is a "perfect black body". Absorbs all radiation. There's a whole host of stuff about this in physics, including, I think, Planck's (Nobel Prize winner) black body radiation theory.
