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.
Gymnosperms and angiosperms have flowers! ferns and bryophytes
Answer:
consists of solid rock
Explanation:
Bed rock are solid rock material usually below the soil surface.
They are found at the ocean floor under sediment and other solid materials. Saprolite are bed rocks that have been weathered they are found above the bed rock overlaining it,
saprolite have different composition because it has gone through chemical weathering.
Above saprolite are soil and other loosed particle.
when the depth and structure of a bed rock is determined it help tell about the history of a place.
Above the troposphere lies the stratosphere where jet airplanes fly. Temperatures increase with altitude because of increasing amounts of ozone. The ozone layer within the stratosphere absorbs harmful ultraviolet rays of sunlight. As the mesosphere extends upward above the stratosphere, temperatures decrease.
