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!
The weakness of hydrogen bonds between the bases of DNA allow DNA to separate. DNA needs to be able to separate so it can duplicate.
C. Not evolve because in a gene pool the frequency does not change from generation to generation.
Answer:
They have a long fiber so they can carry messages up and down the body over long distances. In a stimulated neuron, an electrical nerve impulse passes along the axon. The axon is insulated by a fatty sheath - the fatty sheath increases the speed of the nerve impulses along the neuron.
