| What is Atomic mass, Atomic #, and Isotopes? | 1. Atomic mass -is the number of protons + neutrons in an element 2. Atomic #- the number of protons in the nucleus 3. Isotope- element contains same # of protons but different # of neutrons |
| What is an acid and what is a base? | Acids- release hydrogen ions (H+) in solution , a weak acid dissociates very little as opposed to strong acid , has pH less than 7 and has more H+ than OH- Bases- release hydroxide ions in solution (OH-) , pH more than 7, more OH- than H+, alkaline. |
| What are the functions of the following organelles: 1.Plasma Membrane 2.Golgi Apparatus 3. Lysosomes 4. Peroxisomes 5. Mitochondria 6.

Command Center of the cell, contains genetic material |
| Name and describe the 3 Junction Types | Desmosomes- like "velcro" or "spot welds", hold adjacent cells together, ex skin cells Gap Junctions- membrane channels of adjacent plasma membranes connect to each other , permeable Tight Junctions- joined by "collars" molecules can't permeate |
| Describe: 1. Basement Membrane 2. Stratum Corneum 3. Hypodermis | 1. formed by basal and fibroreticular laminae, mitosis occurs 2. the most superficial layer of the epidermis 3. deepest layer, connects the skin and the underlying structures |
| What are the functions of the skin ? | Protection, Sensation, Flexibility, Hormone Production, Excretions, Immunity, Temperature regulation and Homeostasis |
