Size and foreignness are not, by themselves, sufficient to make a molecule immunogenic; other properties are needed as well. Which one is not correct immunogenic properties?

#Unit 4. Cell Communication and Cell Signaling
  1. synthetic homopolymers  (polymers composed of a single amino acid or sugar) tend to lack immunogenicity regardless of their size.
  2. that copolymers composed of different amino acids or sugars are usually more immunogenic than homopolymers of their constituents.
  3. greater the phylogenetic distance between two species causes lower immunogenic 
  4. bovine serum albumin (BSA) is not immunogenic when injected into a cow but is strongly immunogenic when injected into a rabbit.

After the drought of 1977, researchers hypothesized that on the Galápagos Island Daphne Major, medium ground finches with large, deep beaks survived better than those with smaller beaks because they could more easily crack and eat the tough Tribulus cistoides fruits. A tourist company sets up reliable feeding stations with a variety of bird seeds (different types and sizes) so that tourists can get a better look at the finches. Which of these events is now most likely to occur to finch beaks on this island?
