The recessive allele is the short pea plant gene.
The dominant allele is the tall pea plant gene
reference refers to something that is not moving with respect to an observer that can be used to detect motion. But if they use objects outside the bus as their frame of reference, they can tell they are moving.

Helium is found in the 1st period of the periodic table. It also is part of the noble gases group in the last column (18th) of the table.
In the bohr model of the hydrogen atom, the energy required to excite an electron from n = 2 to n = 3 is <u>greater than</u> the energy required to excite an electron from n = 3 to n = 4
Bohr's energy levels:
The essential concept of Bohr's atomic model is that electrons occupy specified orbitals that call for the electron to have a certain amount of energy. An electron needs to be in one of the permitted orbitals and have the correct amount of energy needed for that orbit in order to be in the electron cloud of an atom. An electron would require less energy to orbit near the nucleus, while an electron would need more energy to orbit away from the nucleus. Energy levels are the potential orbits. One of Bohr's models' flaws was that he was unable to explain why just specific energy levels or orbits were permitted.
It is evident that the energy required to escape an electron from n=2 to n=3 is greater than the energy required to exit an electron from n=3 to n=4. This is because as n increases, the energy levels move closer to one another.
