1 population
2 community
3 ecosystem
4 biosphere
_______ Organs are composed of tissues, which are composed of cells. This is an example of:
1 Living things grow and develop
2 Living things respond to stimuli
3 Living things maintain themselves by homeostasis
4 Living things have levels of organization
5 Living things are adapted to their environment
______ Which of the following is composed of two or more tissue types that come together to perform a function?
1 organs
2 organ systems
3 organisms
4 cells
5 macromolecules

2 cells - tissues - organ systems - organs - organism
3 tissues - cells - organs - organ systems - organism
4 tissues - organs - organ systems - organism - cells
5 cells - tissues - organs - organ systems – organism
_______ Which of the following is the correct order of levels of organization from small to large?
1 cell - organ - tissue - organ system – organism - population - community - ecosystem
2 cell - tissue - organ system - organ - organism - population - community - ecosystem
3 cell - tissue - organ - organ system – organism - community - population - ecosystem
4 cell - tissue - organ - organ system – organism - population - community - ecosystem

_______ What is the name of all the chemical energy transformations that occur within a cell?
1 evolution
2 metabolism
3 adaptation
4 homeostasis
5 photosynthesis
______ What do we call the maintenance of internal conditions of an organism within a certain boundary range?
1 evolution
2 metabolism
3 adaptation
4 homeostasis
5 photosynthesis
_______ Over the course of twelve to twenty four hours after the last meal, a person’s blood sugar level normally varies from about 60 to 130 milligrams per 100 milliliters of blood. The blood sugar level is maintained within a fairly narrow range in spite of uneven intake of sugar, (eating meals 2-3 times per day) this due to the body’s ability to maintain:
1 adaptation
2 inheritance
3 metabolism
4 homeostasis
5 all of the above

5 Response to stimuli
______ Which of these is the process by which a species changes over time?
1 evolution
2 metabolism
3 hydrolysis
4 homeostasis
5 photosynthesis
______ The following statements are true about all living things EXCEPT
1 They are made of cells or cell products.
2 They are the products of evolution.
3 They are composed of carbon, hydrogen, oxygen, and nitrogen.
4 They undergo growth and development.
5 They are multicellular.
______ One reason plastics are not living is that:
1 they do not contain carbon
2 they are not responsive
3 they cannot diffuse
4 no one loves them
______ Which of the following is NOT one of the characteristics of living organisms?
1 to have DNA
2 to respond
3 to grow
4 to metabolize
