Biology: Chapter 1 What is Biology?

What Do You Study as a Biologist?  Interactions of Living “Things”  Must have ALL of the following to be considered “LIVING” = “ORGANISM”  Characteristics of Life:  Orderly Structure  Reproduce (a.k.a. Sex)  Growth / Development  Adapt to Environment  Interactions of Living “Things”  Must have ALL of the following to be considered “LIVING” = “ORGANISM”  Characteristics of Life:  Orderly Structure  Reproduce (a.k.a. Sex)  Growth / Development  Adapt to Environment

ESSENTIAL QUESTION(S):  How does having an ADAPTATION relate to being a living organism?  How does an organism “get” these “ADAPTATIONS?”  How does having an ADAPTATION relate to being a living organism?  How does an organism “get” these “ADAPTATIONS?”

Evolution?  “SPECIES” = group of organisms that can interbreed and produce fertile offspring.  Gradual change in a species over time through adaptations.  Whale Evolution?

Methods of Biology  Observation - Use senses to obtain information.  Hypothesizing - an explanation to a question that can be tested.  Experimenting - Set of “test” of a hypothesis.  Observation - Use senses to obtain information.  Hypothesizing - an explanation to a question that can be tested.  Experimenting - Set of “test” of a hypothesis.

Nature of Biology Section 1.3

“Variables”  Independent Variable = “thing” that changes.  EX: AMOUNT OF FERTILIZER  ON X - AXIS  Dependent Variable = depends on the independent variable.  EX: PLANT GROWTH  On Y-AXIS  Independent Variable = “thing” that changes.  EX: AMOUNT OF FERTILIZER  ON X - AXIS  Dependent Variable = depends on the independent variable.  EX: PLANT GROWTH  On Y-AXIS

Data = Information about Question.  Quantitative = Quantities; displayed graphically.  Qualitative = observational data; written descriptions  EX = Animal behaviors  Quantitative = Quantities; displayed graphically.  Qualitative = observational data; written descriptions  EX = Animal behaviors
