WGU C190 STUDY GUIDE
1.atom: basic unit of matter
2.molecule: chemical structure consisting of at least 2 atoms held
together by a chemical bond
3.cell: fundamental unit of life
4.organelle: compartment inside the cell that contain specific groups of
macromol- ecules and carry out specific cellular functions
5.microorganisms: single celled life form
6.tissue: formed when many different kinds of cells work together to
fulfill the same detailed function
7.organs: collections of tissues that work together to carry out a common
function
8.organ system: higher level of organization that consists of
functionally related organs
9.organisms: individual living entities that survive and reproduce as a un
10.population: consists of all the individuals of a species living in a specifi
area
11.community: populations that can interact with each other in a
positive or nega- tive way
12.ecosystem: consists of all the living things in a particular area with
the abiotic parts of the environment
13.biosphere: collection of all ecosystems on earth
14.emergent properties: characteristics of a system that are not present

, in any of its component parts
15.homeostasis: the ability or tendency of organisms and cells to
maintain stable internal conditions
16.pseudoscience: any claim that purports or pretends to be scientific
in nature but does not actually have the characteristics of true
scientific inquiry
17.biological macromolecules: special molecules that contain carbon
atoms co- valently bonded with hydrogen atoms
18.carbs. lipids. proteins. nucleic acids: 4 classes of biological
macromolecules
19.chemical bonds: attractions between atoms that hold atoms and
molecules together
20.covalent bond: very stable, electron pairs are shared
21.weak: are hydrogen and ionic bonds weak or strong
22.solvent: the component of the solution in the greatest quantity
23.solute: the component present in lower quantities
24.cohesion: molecules bond to each other
25.adhesion: molecules bind to other molecules
26.organic molecules: any molecule that contains a C to H covalent bond
27.C6H12O6: ex or organic molecule
28.store energy provide structural support facilitate communication:
function of carbohyrdrate
29.provide long term energy serve as structural component: function of lipid
