III. Characteristics of Living Things Continued…..
___________ and _____________ ___________ = an increase in the amount of __________ __________and the formation of ______ ____________. __________________________________ Organisms must be able to respond to stimuli in their environment. The regulation of an organism’s environment to maintain conditions suitable for its survival is called _______________________.

12
Grow and Develop
13
Living Things adapt and ______________
Any inherited structure, behavior, or internal process that enable an organism to respond to environmental factors and live to produce offspring is called an ________________ The gradual change in a species over time is _________________. Evolve adaptation Evolution

B. Experimenting What is a controlled experiment?
*most experiments involve 2 groups: The ______________= the part of the exp that is the standard against which result are compared. (nothing changes) The __________________ = the test group that receives experiments treatments (something has been changed) Control Group Experimental Group
19
Designing an experiment
____________________ = the condition in the exp. That is tested _________________= the condition that results from changes in the independent variable. Independent Variable Dependent Variable
