1 / NAS 2 TCC study guide
1.What is the purpose of the scientific method?: The scientific method is an organized way to study the natural world and find out how it works.
2.What are the steps of the scientific method?: Ask a Question. Do Background Research .
Construct a Hypothesis .
Test Your Hypothesis by Doing an Experiment. Analyze Your Data and Draw a Conclusion.
Communicate Your Results.
3.Distinguish between independent and dependent variables: An
independent variable is the variable that is changed or controlled in a
scientific experiment to test the effects on the dependent variable .
A dependent variable is the variable being tested and measured in a scientific experiment .
4.Distinguish between control and experimental groups: An experimental 2 / group is the group in an experiment that receives the variable being tested. One variable is tested at a time. The experimental group is compared to a control group, which does not receive the test variable .
5.Distinguish between hypothesis and theory.: A hypothesis is an attempt to explain phenomena. It is a proposal, a guess used to understand and/or predict something. A theory is the result of testing a
hypothesis and developing an expla- nation that is assumed to be true about something.
6.Define Anatomy and Physiology: Anatomy is the study of the structure and relationship between body parts .
Physiology is the study of the function of body parts and the body as a whole.
7.Identify the six levels of organization (chemical, tissue, etc.): 1) Chemical Level
2) Cellular level 3)Tissue level 4)Organ level 5)Organ system level ) Organismal level
8.Identify the requirements for life:: 1. Reproduction 2. Response/reaction to environment 3. Metabolism 4. Growth.
9.Identify survival needs:: survival needs (5): nutrients, oxygen, water, stable body temperature, and atmospheric pressure
10.What is homeostasis?: The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning, regardless of the outside changing conditions .
