The answer to this is C. Industry. It's the only man made factor.
The answer is : Thermosphere. At this point the homosphere (troposphere, stratosphere and mesosphere) ends at about 80 km from the surface, gas molecules<span> are here</span>bombarded<span> by X-</span>rays from the sun<span> and subsequently form the ionosphere.
Hope this helps! :)</span>
I'm 99.9% sure its lysosomes.
Answer:
To produce energy in form of ATP
Explanation:
The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors. These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP. Later on these electrons will reach the other photosystem, to produce reducing power. This is in plants.
Cyclic photosystems also exist, in some bacteria, for example, and only produce energy as ATP. They also have an electron transport chain.
