Florida Biology EOC Review UPDATED
Exam Questions and CORRECT Answers
Independent Variable - CORRECT ANSWER - - what is being changed or tested during
experiment; cause
Dependent Variable - CORRECT ANSWER - -what is being measured or observed during
experiment; effect
Control Variable - CORRECT ANSWER - -use as the comparison "group" in an
experiment
What makes an experiment reliable? - CORRECT ANSWER - -has been tested numerous
times by more than one scientist
-it follows steps of scientific method
-no bias
-information came from third party
-study been retested
-results are published in scientific journal
Theory - CORRECT ANSWER - -are subject to revision and modification over time
Laws - CORRECT ANSWER - -developed when observations around the world are tested
and retested until there is a consensus in a scientific community; not changed over time
Dissection Light Microscope - CORRECT ANSWER - -lowest magnification for
microscopes
-views organs and tissues during dissection
-views 3D specimens
, Compound Light Microscope - CORRECT ANSWER - -40x to 400x
-views tissue samples, blood, microorganisms, and larger details of some cells
-common classroom microscope
Transmission Electron Microscope - CORRECT ANSWER - -passes a beam of electrons
through a thin specimen
-mainly used to study internal structures of cells that cannot be viewed under light microscopes
Scanning Electron Microscope - CORRECT ANSWER - -electron beam passes over
specimens surface that is coated with thin layer of gold metal
-studies details of specimen's surface
-3D and black&white
Polar Molecules - CORRECT ANSWER - -have an end that is slightly positive and an end
that is lightly negative
-water
Hydrogen Bonding - CORRECT ANSWER - -attraction between the slightly positive
hydrogen of one molecule and the slightly negative oxygen of another water molecule
Surface tension - CORRECT ANSWER - elastic-like forces existing on the surface of a
liquid caused by asymmetry in the attractive forces between the liquid molecules
Cohesion - CORRECT ANSWER - when two like substances attract to one another
Adhesion - CORRECT ANSWER - when two unlike substances attract
universal solvent - CORRECT ANSWER - water can dissolve into many substances: ionic
compounds and polar molecules dissolve easily in water
