An electron in a hydrogen atom moves from level 1 to level 4. the electron then drops from level 4 to level 2. which statement describes the most likely result?

It would be B. In the first move energy was absorbed, because when energy is gained an electron moves to a higher energy level. In the second move energy was released because that is how an atom moves to a lower energy level.  The jump from level 1 to  4 was bigger than the drop from 4 to 2, because in the first move it moved from more orbitals.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
