| From smallest to largest, the levels of organization of the body are: | chemical, organelle, cellular, tissue, organ, system, organism |
| The total number of electrons in a neutral atom equals the number of | protons in its nucleus |
| Atoms with fewer than eight electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability. This tendency is called the | Octet rule |
| What decomposition reaction requires the addition of a water molecule to break a bond? | hydrolysis |
| Chemical bonds formed by the sharing of electrons are called: | covalent |
| Which type of chemical reaction results in the breakdown of a complex substance into two or more simpler substances? | decomposition reaction |
| An atom can be described as chemically inert if its outermost electron shell contains _____ electrons. | eight |
| For sodium to transform from a neutral atom to a positive ion, it must: | lose an electron |
| The most abundant element essential to life is | carbon |
| Acids: | are proton donors, taste sour, and release hydrogen ions in an aqueous solution. |
| the only organelle that has a double membrane structure is the | mitochonrion |
| Cisternae of this organelle are continuous with the nuclear envelope. | endoplasmic reticulum |
| This organelle primarily modifies products from the rough ER, and it resembles a stack of hollow saucers, one cupped inside the next. | Golgi apparatus |
| The presence of which substance in the cell membrane keeps it from breaking too easily | Cholesterol |
| The term _____ is used to describe a muscle that directly performs a specific movement. | agonist |
| The sternocleidomastoid muscle is an example of a muscle named for its: | points of attachment |
| Muscles that contract at the same time as the prime mover are called: | Synergist/Antagonists |
| Fibrocartilage can be found in the | symphysis pubis |
| Why are the last two pairs of false ribs designated as floating ribs? | Floating ribs do not attach even indirectly to the sternum |
| _____ fibers are present in all three types of cartilage, but they are most numerous in fibrocartilage. | Collagenous |
| The extracellular components of bone matrix are | hard and calcified |
