Which of the following are proteins? O cholesterol O ion channels O phospholipids O glycolipids O none of the above

Phospholipids

1- (True or False) Adjacent nucleotides are joined by covalent bonds that form between the –OH group on the 3` carbon of one nucleotide and the phosphate on the 5` carbon on the next.   2- (True or False) if a solute is in an aqueous solution, then by definition an hydration shell has formed around it.   3- (True or False) When exposed to water, phospholipids will self-organize into lipid bilayers, and spheres.
