This is the chemical equation for photosynthesis
6CO2+6H2O--->C6H12O6+6O2
the inputs are the ones on the left:
carbon dioxide used in the calvin cycle and water used in the light-dependent reactions
the outputs are on the right
glucose resulted from the calvin cycle and oxygen resulted from the light dependent reactions
<span>A. The nebula contracts and shrinks instead of expanding
</span><span>Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites.
