,Describe the levels of organization in multicellular organisms starting with atoms
and ending with organisms. - Correct Answer: Atoms,Molecules<organelles,cells,tissues,
organs,systems,organisms
Define the term homeostasis. - Correct Answer: The maintenance of dynamic steady in the internal
environment "strive for stability"
Describe, in general terms, how negative and positive feedback mechanisms are
used by organisms to maintain homeostasis. - Correct Answer: +/- feedback: The general mechanisms of
nervous or hormonal regulation.
- feedback: Provides stable, long term control.
+ feedback: Reinforces original deviation and causes rapid and temporary changes in a variable.
State the basic units of the metric system for length, mass, time and volume. - Correct Answer: BASE
UNITS
Meter (m) - Length
Gram (g) - Mass/Weight
Liter (l) - Volume
Degree Celsius (ºC) - Temperature
Second (s) - Time
