Plants convert the electromagnetic energy of photons into chemical energy stored in atp molecules. an equivalent of 54 atps are then used to make each glucose molecule in the calvin cycle. when cells break glucose molecules down to smaller molecules like carbon dioxide and water they are only able to create 38 atp molecules. what fundamental scientific principle accounts for the difference in those numbers of atp molecules?

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
