Explanation:

Since this is a set of Anatomy and Physiology review questions, let's answer one of them, for example, question 1 (Chapter 1 & 2: What determines the reactivity of a given atom?):

The reactivity of an atom is determined by the number of valence electrons (electrons in the outermost energy level). Atoms tend to gain, lose, or share electrons to achieve a stable electron configuration (like a full outer shell, e.g., 8 electrons for most, 2 for hydrogen/helium), and the number of valence electrons dictates how easily they can do this.

Epithelial tissue is a type of tissue that covers body surfaces (external or internal linings of organs/cavities), forms glands, and functions in protection, absorption, secretion, and filtration. It has tightly packed cells with little extracellular matrix, and often has a basement membrane.

1. Sagittal Plane: Divides the body (or organ) into left and right parts. A midsagittal plane divides into equal left/right; parasagittal into unequal.
2. Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) parts.
3. Transverse (Horizontal) Plane: Divides the body into superior (upper) and inferior (lower) parts (or proximal/distal for organs).
4. Oblique Plane: Divides the body at an angle (not 90° to sagittal/frontal/transverse), used less commonly but useful for specific structures.

Answer:

The number of valence electrons (electrons in the outermost energy level) determines an atom's reactivity. Atoms react to achieve a stable electron configuration (e.g., full outer shell), and valence electrons dictate how easily they gain/lose/share electrons.
