ATI TEAS
# Term Definition
1 Isotope An Atom with different # of neutrons
2 Ion An Atom different number of Electrons
3 Neutral State Protones and electrons are equal
4 (+) charged Cation Atom lost an Electron
5 (-) Charged Anion Atom gained an Electron
6 Covalent Bond Two atoms share Electrons
7 Ionic Bond Atom that needs an Electron stills one or more
to complete its shell
8 Isotope Version of the same element with Different
number of neutrons
9 Boiling point The temperature at witch a substance changes
its state form from Liquid to Gas
10 Melting point The amount of Energy needed to change a
substance from Solid to Liquid (quantity of a
substance is taken into consideration)
11 Specific heat capacity A measure of the amount of energy needed to
bring the temperature of one gram of a
substance up by 1 degree Celsius
12 Properties of a substance --> luster -->Conductivity --> Malleability -->
Density
13 Intensive properties Physical properties that are independent of the
the amount of substance present
14 Extensive properties Are those characteristics of a substance that
depends on the size of a sample [ Length,
Volume, Mass]

# Term Definition
15 Osmosis The movement of water trough a
semi-permeable membrane *In cells,
Movement through aqua porin channels
16 Diffusion The passive movement of a substance from
areas of [high] to [low] concentration
17 cell Basic organizational unit of all living things
18 Phospholipid membrane Has holes made of proteins that help cetain
molecules and ions to move in and out
19 Cell is filled with.. - cytoplasm --> cellular contents between
plasma membrane and the nucleus - cytosol-->
The fluid portion of the cytoplasm A.k.A
Intracellular fluid.
20 Structural Levels -Chemical level -Cellular level -Tissue level
-Organ level -System level -Organism level
21 Chemical Level Atoms and molecules, Molecules= two or more
atoms combined 'ie: C, H, O, N, P, Ca, S Glucose,
Deoxyribonucleic Acid DNA
22 Cellular Level Molecules combined to form cells ie: Muscle
cells, Epithelial cells,
23 Tissue Level Group of cells and materials surrounding them
that work together to perform a particular
function Epithelial tissue. Connective tissue,
muscular tissue, Nervous tissue`
24 Organ Level Different types of tissues joined together,
Organs are composed of two or more different
types of tissues. Stomach, Heart, Skin
25 System Level Related organ with common functions, ie:
Digestive System
26 Organism Level A living Indevidual
27 Somatic Division Voluntary FXN: Controls the skeletal muscles of
the body
