What happenes when an election moves to a higher energy level?

Do you mean electron, if an electron moves to higher energy level then it has low electronegative and its hard for that element to lose an electron. Atomic radius increases

The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).

the answer is c.) there is a warm front in region a and a stationary front in region b.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
