segment of DNA, contains coding for polypeptide or protein; unit of hereditary info


organism that obtains organic food molecules by eating organisms or their by-products

multicellular organism

living thing, consists of more than one cell

natural selection

process which organisms w/ favorable variations reproduce at higher rates than those w/o such variations


an individual animal, plant, or single-celled life form.


conversion of light energy into chemical energy stored in organic compounds

sexual reproduction

production of offspring from combination of genetic material from two parent organisms

unicellular organism

living thing composed of one cell


process which an organism grows


sum of all chemical processes in living things

control group

in experiment a group or individual that serves as a standard of comparison w/ another group or individual to which it is identical except for one factor

controlled experiment

test of variables using a comparison of a control group w/ an experimental group

dependent variable

responding variable in an experiment


a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact

experimental group

subject that receives the independent variable


statement that can be tested experimentally

independent variable

an experimentally manipulated variable


an assumption based on your observations. cannot be seen directly


something you can actually see, feel, hear, taste or smell. use senses directly.


a thing predicted; a forecast


test small group, assume it's true for everything


broad and comprehensive statement of what is believed to be true, supported by considerable experimental evidence resulting or many tests of related hypothesis
