Bio 101 Study Guide
BIO EXAM 1
BUILDING BLOCKS
Aminoacids->Proteins->Enzymes
Glucose=Polysaccrides
Glyseral=Fat Molecule
Neoclotides= DNA & RNA
CRITERIA OF LIFE: (5)
A. Biology: What is it?: BIOLOGY: is the scientific study of life
B. What is life? -- Criteria for life: All living organisms have similar properties -composed of cells made up of macromolecules -growth, development & reproduction -heritable information in the form of DNA -sensitivity to stimuli -homeostasis (maintenance of internal environment) -use of energy 1. Definite Structure or Organization 2. Responsiveness (irritability)-> flinching 3. Movement->all moves in its lifetime 4. Metabolism-> energy compounds, burns calories 5. Homeostasis-> consistent internal balance while external environment changes 6. Growth and development-> changing form as life ages 7. Reproduction->making more of one species 8. Evolution->adaptation over time 10. The particular combination of above impt
D. Unifying principles of biology 1. Evolution: two stage process: a. genetic variations b. selection acting on this variation 2. Energy-> for reproduction (purpose of life)
E Impt. of bio. to citizen medicines from plants: human ethics: political decisions: human curiosity:
SCIENTIFIC METHOD: (1)
F. Who uses biological concepts
Biologists use the scientific method to study the processes that affect living things
Biologists explore life at levels ranging from the biosphere(life on earth) to molecules that make up cells
G. What is science: The word SCIENCE is derived from a Latin verb meaning “to know”
All braches of science acquire knowledge via the scientific method
1. DEDUCTIVE REASONING: leads one to infer something specific from a general premise example: All boys are bad>>>John is a boy >>>Therefore John is bad
2. INDUCTIVE REASONING: leads one to infer general
