In phospholipids, at least one fatty acid chain is “kinked”, resulting in a bent structure. This phenomenon, which gives fluidity to cell membranes, is caused by *         Excess hydrogen atoms around the bond       Hydrophobic interactions       Multiple ionic bonds       Multiple double bonds

Oils/Fatty acids have both a polar-head and a long tail that is non-polar. The term for a molecule with both polar (hydrophilic) and non-polar (hydrophobic) ends is   Group of answer choices amphiphilic amphoteric zwitter ion lipid

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.
