Answer:
C
Explanation:
ight provides the energy for breaking apart sugars into small molecules. ... They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane
Answer:
18
Explanation:
8CO₂ + 18H₂O + energy ⟶ 3C₆H₁₂O₆ + O₂
C is balanced
.
We have 54 O on the left-hand side, but only 20 O on the right-hand side.
We need 34 more O atoms on the right, for a total of 36. Put an 18 in front of O₂.
18CO₂ + 18H₂O + energy ⟶ 3C₆H₁₂O₆ + 18O₂

It checks.
Remember, diffusion is when molecules move from an area of HIGH concentration to an area of LOW concentration. Therefore, in this example the molecules on the outside, where the concentration is high, will diffuse to the inside of the circle, where the concentration is low.
