the cell is the:
cells preform all the:
New cells come from the:
basic unit of all living things
function of the living things
reproduction of other cells
Activation energy -
Catalyst -
Enzyme -
Organ system -
energy required to start an action
affects the rate of the reaction start
organic catalyst
made up of several organs that work together
dynamic equllibrium in which an organism is interacting with its environment to maintain balance
Organisms are made of:
cells multiply by:
cells
dividing
Tissue process:
1 cells
2 Tissues
3 organs
4 systems
5 organ systems
6 organism
optimal point -
optimal range -
precise conditions at which something functions best
the range in which performance limited for stability
Cell membrane -
Phospholipid layer -
outermost boundary of every cell
a layer that all boundaries are made of
