LEVEL 1 - Cells
Are the basic unit of structure and function in living
things.May serve a specific function within the
organism
Examples- blood cells, nerve cells, bone cells, etc.
tissue
LEVEL 2 - Tissues
Made up of cells that are similar in structure and
function and which work together to perform a specific
activity
Examples - blood, nervous, bone, etc. Humans have 4
basic tissues: connective, epithelial, muscle, and
nerve.
LEVEL 3 - Organs
Made up of tissues that work together to perform a
specific activity
Examples - heart, brain, skin, etc.
LEVEL4 - Organ Systems
Groups of two or more tissues that work together to
perform a specific function for the organism.
Examples - circulatory system, nervous system,
skeletal system, etc.
LEVEL 5 - Organisms
Entire living things that can carry out all basic life
processes. Meaning they can take in materials, release
energy from food, release wastes, grow, respond to the
environment, and reproduce.
Usually made up of organ systems, but an organism may
be made up of only one cell such as bacteria or
protist.
Examples - bacteria, amoeba, mushroom, sunflower,
human

1)Atom: The smallest unit of matter that retains the properties of an element.
2) Ion: An atom that has gained or lost electrons thus acquiring a charge.
3) Electronegativity: The attraction of an atom for the electrons of a covalent bond.
4) Hydrogen Bond: A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom a polar covalent bond in another molecule.
5) Hydrophilic: Having an affinity for water.
6) Cohesion: The binding together of like molecules, often by hydrogen bonds.
7) Capillary action: Physical effect caused by the interactions of a liquid with the walls of a thin tube. The capillary effect is a function of the ability of the liquid to wet a particular material.
8) Organic Compound: Ccontains carbon chemically bound to hydrogen. Organic compounds often contain other elements (particularly O, N, halogens, or S).
9) Polar Covalent Compound: A type of covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
10) Molecule: Two or more atoms held together by covalent bonds.
11) Isotope: One of several atomic forms of an element, each containing a different number of neutrons and thus differing in atomic mass.
12) Ionic bonding: A chemical bond resulting from the attraction between oppositely charged ions.
13) Nonpolar covalent bond: A type of covalent bond in which electrons are shared equally between two atoms of similar electronegativitiy.
14) Hydrophobic: Having an aversion to water; tending to coalesce and form droplets in water.
15) Adhesion: The attraction between different kinds of molecules.
16) Monomer: The subunit that serves as the building block of a polymer.
17) Inorganic compound: Combination of two or more elements other than those used to form organic compounds.
18) Chemical bonding: An attraction between two atoms resulting from a sharing of outer-shell electrons or the presence of opposite charges on the atoms the bonded atoms gain complete outer electron shells.
19) Covalent bond: A type of strong chemical bond in which two atoms share on pair of valence electrons.
20) Solvent: The dissolving agent of a solution. Water is the most versatile solvent known.
21) Solute: A substance that is dissolved in a solution.
22) Heat Capacity: The amount of heat it takes to raise the temperature of one gram of a material one degree Celsius.
23) Surface Tension: A measure of how difficult it is to stretch or break the surface of a liquid. After has a high surface tension because of the hydrogen bonding of a surface molecule.
24) Polymer: Polymers are used with other chemical coagulants to aid in binding small suspended particles to form larger chemical flocs for easier removal from water. All polyelectrolyte are polymers, but not all polymers are polyelectrolyte.
25) Macromolecule: A giant molecule formed by the joining of smaller molecules, usually by a condensation reaction. Polysaccharides, proteins, and nucleic acids are macromolecules
Class: Lipid
a. They consist of large biological molecules that doesn't include polymers.
b.10-20 carbon atoms long (A double bond connects the
two, red Carbon atoms.
