2)

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

4)

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
