Atoms of different elements always combine in the same way.
John Dalton noted that if the components are added to one exacerbated, the share of their masses will dependably be the same. Dalton's been an English scholar. The component mass of that mix is measured by the confirmation of the presence of molecules assembled by John Dalton.

Answer:
The correct answer is option e, that is, a, b and c.
Explanation:
The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.
With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.
