The size of a molecule typically ranges from about 1 to 100 nanometers in diameter. In scientific notation, this can be expressed as approximately (1 \times 10^{-9}) meters to (1 \times 10^{-7}) meters. For example, a typical small molecule like water has a molecular size on the order of (2.75 \times 10^{-10}) meters.

It's not necessary to put numbers of this size into scientific notation but if you really have to, go with 4.125 x 10^0
It's not necessary to put numbers of this size into scientific notation but if you really have to, go with 4.215 x 10^0
A proton is 2x10^-14m, or 0.00000000000002m

It depends on the way in which it is written!

0.00001276 meters in Scientific Notation = 1.276 x 10-5 meters.
A proton is 2x10^-14m, or 0.00000000000002m
Proxima Centauri is a star and there is no scientific notation for a star. There will be scientific notations for the values of its distance, its size, its age, luminosity, magnitude and so on but the question is not about any of them!
Only if the numbers to be converted into scientific notation are the same otherwise the exponents can vary according to the size the numbers.
An african elephant is approx 3.3 metres high.
Amoeba proteus typically measures about 0.5 to 1 millimeter in length. In scientific notation, this size can be expressed as approximately (5 \times 10^{-1}) to (1 \times 10^{0}) millimeters.
It is 8.9*10^-5 in scientific notation
