Pretty sure its all called a sphere.
The answer is B
An open system has its energy and matter leave and enter the system's boundaries unlike in a closed system where energy remains within the system.
The earth's atmosphere shares heat and water vapor with the hydrosphere (oceans, seas and lakes), energy form the sun, in the atmosphere and then partly radiated back to space
Answer: (B) to function as the final electron acceptor in the electron transport chain.
Explanation:
Oxidative phosphorylation is a process that takes place in cellular respiration. It consists of two component pathways which includes the electron transport chain (etc) and chemiosmosis.
In etc the electrons are passed from one to another molecule, the energy is released by the electrochemical gradient.
In chemiosmosis, the energy stored in the electrochemical gradient is used to produce energy molecules in the form of ATP (Adenosine triphosphate).
The oxygen is present at the end of the etc. It's function is to accept the electrons also picks up the protons to form water. If oxygen is absent then no molecule will accept the electrons, the electron transport chain will stop. There will be no chemiosmosis as the ATP will not be produced in the absence of formation of a electron gradient.
Answer:
Evaporation and transpiration

Atmosphere receive water through this process
