Answer:
. The explanation given by a theory is well tested and supported by many observations and hypotheses.
Explanation:
A theory is a scientific explanation for a given phenomenon. The explanation provided by a theory are usually derived from a well tested hypothesis and experiment.
A hypothesis is a scientific guess of phenomenon. It is upon the hypothesis that most experiments are predicated.
Before a theory is developed from a hypotheses, it must be well tested and proven to be true.

A control group is sort of the normal group. The group you aren't changing or messing with. It is to show what the species/experiment acts like on its own in response to something without you having to change it at all.
With an experimental group, you are changing something about the subject before putting it in the conditions it will need to respond to.
I don't entirely understand, but I know the control group is constant, unchanging. It sort of helps with distinguishing things. I have examples of experiments if that will help you understand what a control group is to answer the question. I also have a The Death Cure example if you have seen or read the book. I hope you do not fail this assignment, but even if I did not answer with an answer you were looking for, it could have helped you answer the question on your own.
I saw somewhere a similar question, though I was given the answer choices. If this is the answer you are looking for: variable(s).
Control groups don't use variables because you aren't changing them.
Answer:
Water
Explanation:
When a colloid such as a gelatin forms, water is entrapped by the process of protein coagulation.
Colloids can be describes as particles of solid having spherical diameter between 1 and 100 nm which are dispersed in the liquid medium. Coagulation can be described as a process in which particles aggregate and lead to the formation of flocs. Flocs can either settle in water or can easily be seperated from water.
