They only tested two to have a solid hypothesis you need a larger group.
Option B i.e A Divide is the correct answer.
The Rocky mountains are also called a Divide or Continental Divide of Americas because these mountains separate river system flow in the pacific ocean and the river system which flows in the Atlantic ocean. The Continental divide is also called as the Great Divide.
The part of an atom that is mostly empty space is the electron cloud
The correct answer is: In both systems, ATP is produced by chemiosmosis.
Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).
