Remember that a dependent variable is a variable that is being measured in a experiment so in this case your answer would be option C "plant height." Since how they are measuring plants height.
Hope this helps!
Answer:
Friction is the force between an object in motion and the surface on which it moves. Friction is the external force that acts on objects and causes them to slow down when no other external force acts upon them.
Answer:
In order to attain stability
Explanation:
Every chemical bonds that are formed results from the desires of atoms to achieve stability like the inert and nonreactive noble gases. By so doing, their outer shell electrons must be completely filled to attain an octet configuration like the noble gases with eight outermost electrons.
An atom of oxygen has six outer electrons. To complete its octet, it will require just two more electrons.
This desire will make it bond with another atom. In the vicinity of another oxygen atom, it will bond. The type of bond formed will be a covalent bond which results from each of the oxygen atom sharing two of their valence electrons.
The joint shared electrons will now be four electrons. This four electrons will make each of their octet complete and a covalent bond occurs.
