diffusion - <<ANSWER>>the movement of molecules from an area of high
concentration to one of lower concentration
osmosis - <<ANSWER>>the movement of water across a selectively permeable
membrane in order to equalize the concentration on two side of the membrane
active transport - <<ANSWER>>uses proteins and energy to pump material through the
cell membrane against a concentration gradient

cell
, chromosomes - <<ANSWER>>structures that carry the genetic information
prokaryotic cells - <<ANSWER>>lack a true nucleus and organelles; have a cell wall

troposphere - <<ANSWER>>near the surface of Earth; where weather takes place and
the location of almost all clouds; pressure and temperature decrease with height in this
layer
stratosphere - <<ANSWER>>less dense and temperature increases with height;
absorbs much of the ultraviolet energy from the sun
