b.temperature change
c.high concentration of salt
d. ionizing radiation
Term
Lipids
Definition
Made of mostly carbon and hydrogen, have very little ocygen.
Concentrated energy storage molecule.
Non-polar, so they are not easily soluble.

Term
Secondary Metabolites have 4 functions.
What are they?
Definition
1.Chemical Signaling
2.Chemical Defense
3.Protective from UV Radiation
4.Animal Attraction (for the purpose of pollination.

Definition
Have dramtic physiological effects on mammalian physiology and central nervous system.
Term
Most cell are microscope. What must be use to see them and what are the two kinds used?
Definition
A microscope
A light microscope : cells and large organelles only.
An electron microscope : very good picture.
