Please help <3 Read the following scenario and state which of the following could be a control group?

I have noticed that in my garden the bean plants that are growing in one area are taller than the bean plants growing in a different area. I think the beans are taller because that area of the garden gets more light than the other area. I have decided to conduct an experiment to see if the amount of light influences bean height.

changing the type of light

changing the type of bean plants

changing the unit of height measured

using no light

Using no light

Explanation:

A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results of that specific group.

Using no light would be the control group in this experiment because the experiment is testing the effect that light has on the growth of bean plants.

hope this helps!

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
