The Study Of Biology

Front 1

Oranization and presence of one or more cells

Back 1

• Organization is the high degree of order within an organism’s internal and external parts
• The same speices have the same body arrangments
• Can be unicellular (one cell)
• mulitcellular (multiple cells)

Front 2

Respond to stimuli

Back 2

-physical change in internal or external environment
• Must be able to react to changes in enviroment
• Owl dilates its pupils to see in the dark

Front 3

Homeostasis

Back 3

- is the maintenance of a stable level of internal conditions even
though environmental conditions are constantly changing
• Organisms have systems that maintain internal conditions- temperature, water content, uptake of nutrients in cells
• Owl burns fuel to keep a temp. of 40 degrees, owls feather fluff up to keep this temp

Front 4

Growth and development

Back 4

division and growing of the cells
• Unicellular cells- cell enlargement
• Mulitcelluar- mature through cell division, cell enlargment, and development- process where an organism becomes a mature adult

Front 5

reproduction

Back 5

- organisms produce new organisms, essential for the continuation of a specie
• Hereditary information can be transferred by sexual (hereditary info recombines from two organisms and produced a similar but not exactly the same from the parents) or asexual (hereditary from different organism is combined to make genetically identical offspring to its parents

Front 6

change through time

Back 6

evolve

Front 7

unity and diversity (theme)

Back 7

• Genetic code- how cells use heredity info in DNA
• “tree of life
o 3 domains (branches)- Bacteria, (Kingdom bacteria) Archaea (kingdom archaea), Eukarya (Animalia, Plantae, Fungi, Protista)

Front 8

interdependence of organisms (theme)

Back 8

• Ecology-is the branch of biology that studies organisms interacting species as well as ecosystems
• Ecosystems- communities of living species and their physical environments

Front 9

evolution of life (theme)

Back 9

• Organisms that have certain favorable traits are better able to survive and reproduce successfully than organisms that lack these traits
• Adaptions- traits that improve an individual ability to survive and reproduce

Front 10

control group

Back 10

provides a normal standard against which the biologist can compare to

Front 11

experimental group

Back 11

is identical to the control group except for one factor (independent variable)

Front 12

independent variable

Back 12

manipulated variable (one that is being changed form each experiment)

Front 13

dependent variable

Back 13

responding variable (what data will you record)

Front 14

controlled experiment

Back 14

compares an experimental group and a control group and only has one variable
