Answer:
An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be identical in all other ways.
<span>The more thermal energy a substance has, the more warmer it will be. So when the temperature is high, there is a lot of thermal energy </span>
Thermal energy is just energy. It refers to the energy of the molecules. Temperature is just a measurement
Answer:
One could be in the cell. The cell respires, thus producing carbon dioxide in it. So the concentration builds up in the cell. Diffusion is the net movement of particles from a region of high concentration to a region of low concentration, and the carbon dioxide concentration outside the cell is less, therefore the carbon dioxide molecules moves outs of the cell.
Another scenario is when perfume is sprayed into the air. The perfume particles collides with the air particles (lower or no concentration of perfume). This process goes on and on. This is diffusion since the concentration perfume particles collides with the less concentrated particles of perfume.
Answer:
The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.
Explanation:
deoxyribose + phosphate group + thymine
Energy can neither be created or destroyed but does however transform from one form to another
