Chapter 1 – Introduction to biology



This is an outline to help students take notes during the Introduction to Biology Lecture. The Powerpoint can be found here: biology – For something to be considered _______________, each of the following must be present: Characteristics of Life Define order – Example:Define adaptation – Example:Define response – Example:Define order – Example:Define regulation – Example:Define reproduction – Example:Define growth / development – Example:Define energy processing – Example:Biological organization is based on a hierarchy of _____________ _____________.Biosphere – Example:Ecosystem –Example:Community – Example:Population –Example:Organism –Example:Organs / Organ systems –Example:Tissue –Cells –Organelle –Molecule -Scientific Method Define observation – What observation was made of the marsh grasses?Define hypothesis – A hypothesis is _______ a guess.What hypothesis is given for the marsh grass observation?Parts of an experiment:Variable – What variables are present in the marsh grass scenario?How many variables should change in an experiment?What does a controlled experiment do?There are two types of variables:The independent variable is ___________________________.What was the independent variable in the marsh grass experiment?The dependent variable is ____________________________.What was the independent variable in the marsh grass experiment? Experiments are usually divided into two groups: The experimental group _________________________________________.The control group ______________________________________________.Quantitative data could be ______________________________________________.What quantitative data was collected in the marsh grass experiment?What conclusion could be drawn from this experiment?What is the most likely source of error in any experiment?How can this be avoided?What is the next most likely source of error?What happens next if a hypothesis is not supported by the experimental data?Define qualitative data:All experiments are published and checked for what two things? Explain bias.Define scientific theory – What two features do all theories have in common? Give an example of a scientific theory:Major Fields of BiologyFor each of the fields of biology, define the field and give an example:FieldDefinitionExample ................
