The tendency of water molecules to stick with another molecule other than water
is....
Adhesion
Which is less dense, solid water or liquid water?
Liquid water-the molecules can fit closer together because they are breaking and
reforming, unlike ice molecules

An oil may be converted into a substance that is solid at room temperature by
adding hydrogen, decreasing the number of double bonds in molecules
Fatty acids with double bonds between some of their carbons are said to be
unsaturated
Primary structure of a protein is
, 3
the amino acid sequence of the polypeptide chain

Plasma membrane
Order in which insulin passes through from its production to its exit from the cell
Rough ER, transport vesicles, golgi apparatus, transport vesicles, cell membrane
