Answer:
<h2>a. adduction </h2>
Explanation:
Adduction is a medical term that is used to describe the movement of the limb toward the body midline or body center. Fingers, toes, limbs and some others follow the adduction. It is a type of motion of the limbs so used in an anatomical study, physiotherapy, exercise, games, and some other fields. In the anatomical study, there are some other medical terms that explain other positions or movements of the body.

Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency
