Why do experiments include control groups?

Biology

Sholpan [36]3 years ago

Control groups are used as a source of comparison in the experiment, so when you are testing the experimental group, you can see how the results are different than the control group. It makes the results more accurate.

So there is something to compare the changed part of the experiment too. The reason why I created a control group for if My plants grew faster in the dark or the light is to compare the growth speed if there was any. I put one on my porch outside where it was under direct sunlight. I put another on my desk where it got light only on certain parts of the day and I put the last one in my closet where it hadn't received any sunlight. in this case my plant on my desk would be my control group.
Hope this helps :D<span />

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan
Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>
  • Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
  • The correlation is that the more plants are present, the less carbon is free in the air.
  • The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
  • As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

Why is a theory called a theory and not a fact?
Black_prince [1.1K]
Many theories can never be proven. 
Here are a few examples:

-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.

None of these statements can be proven.  That's why they're not called
Facts or Laws. 

It also tells you that some pretty powerful stuff has been done with concepts
that can't be proven.  If you want to make an idea look foolish, that doesn't
happen when you say "it's only a theory".
