B.cellular respiration.
C.cellular circulation.
D.cellular transpiration.
Answers;
Cellular respiration;
Explanation;
Food molecules contain biochemical energy which is made available by cellular respiration;
The process of cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy.
The purpose of cellular respiration is to provide cells with the energy they need to functioning and activities such as growth and movement.
Reactant is what ever is started off with (aka every thing on the left side of a reaction equation)
Photosynthesis equation is:
6CO2 + 6H2O -------------> C6H12O6 + 6O2
This means that the reactants are:
6CO2 + 6H2O -------------> C6H12O6 + 6O2
This is carbon dioxide (six of them to be specific) and six waters, light energy is also required
Hope this helped!
OB) A few scientists believe it is correct.
OC) Many scientists believe it is correct.
OD) All scientists believe it is correct.
I think C.Manyscientistsbelieveitiscorrect. because a theory can not be proven therefore some we'll educated scientists could still reasonably believe the theory to be false, even when I hasn't been proven incorrect.
