NAS2 TCC study guide questions with correct
answers
What |is |the |purpose |of |the |scientific |method? |- |CORRECT |ANSWER✔✔-The |scientific |method |
is |an |organized |way |to |study |the |natural |world |and |find |out |how |it |works.
What |are |the |steps |of |the |scientific |method? |- |CORRECT |ANSWER✔✔-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.
Distinguish |between |independent |and |dependent |variables |- |CORRECT |ANSWER✔✔-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.
Distinguish |between |control |and |experimental |groups |- |CORRECT |ANSWER✔✔-An |
experimental |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.
Distinguish |between |hypothesis |and |theory. |- |CORRECT |ANSWER✔✔-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 |explanation |that |is
|assumed |to |be |true |about |something.
Define |Anatomy |and |Physiology |- |CORRECT |ANSWER✔✔-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.
Identify |the |six |levels |of |organization |(chemical, |tissue, |etc.) |- |CORRECT |ANSWER✔✔-1) |
Chemical |Level |
2) |Cellular |level
3)Tissue |level
4)Organ |level
5)Organ |system |level
6) |Organismal |level
Identify |the |requirements |for |life: |- |CORRECT |ANSWER✔✔-1. |Reproduction |2.
|Response/reaction |to |environment |3. |Metabolism |4. |Growth.
Identify |survival |needs: |- |CORRECT |ANSWER✔✔-survival |needs |(5): |nutrients, |oxygen, |water, |
stable |body |temperature, |and |atmospheric |pressure
What |is |homeostasis? |- |CORRECT |ANSWER✔✔-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.
What |are |the |basic |mechanisms |of |homeostasis? |- |CORRECT |ANSWER✔✔-- |Homeostatic |
control |mechanisms |have |at |least |three |interdependent |components: |receptor, |control |center, |
and |effector.
- |The |receptor |senses |environmental |stimuli, |sending |the |information |to |the |control |center.
