B exponential growth
Although it started slow in the beginning it has increased quickly over time
A) Polaris is much farther from Earth than the Sun -is the reason why Polaris although about 46 times larger than the Sun, the Sun appears brighter than Polaris from Earth.
Explanation:
Astronomers define the brightness of a star based on its apparent magnitude and absolute magnitude. The apparent magnitude tells about how bright does a star looks from the Earth. The absolute magnitude of star is its brightness or magnitude at a standard distance of 10 parsecs or 32.6 light-years.
Accordingly,
The apparent magnitude of Sun is 26.74; while that of Polaris is 2.02
The absolute magnitude of Sun is 4.63; while that of Polaris is 3.6
The Sun is at a distance of 0.000015649 light years from the Earth; while the Polaris is 434 light years from the Earth. A star appears brighter from the Earth due to the closeness of the star to the Earth.
All these factors make the Sun appear brighter than the Polaris

Answer:
The answer is ELECTRON TRANSPORT CHAIN.
Explanation:
The electron transport chain are the series of proteins that carry electrons through the membrane of the mitochondria. Mitochondria are the power house of the cells, they are made up of two cell membranes, the electrons transport chain takes place in the inner cell membrane.
The transportation of electrons through the mitochondrial membrane is also called oxidative phosphorylation. During the process of oxidative phophorylation, the energy release is capture in form of proton gradient and this is used to produce ATP via the process of chemiosmosis.
