Hey, i understand that i am only suppose to upload one question at a time but i really need your guys help. I did horrible on my BIO-2 test and I need to know what i did wrong becuase this material is going to be on the final test so I need to know what i did wrong. Please help me with these multiple choice questions. Please answer all of them i would really appreciate it! Thank you so much for your time and help!
reactions would be required to link 209 number of reactions woul number ofmer in a macromolecule. 25. )08 s into a polymer in a m (A) 208, hydrolysis monomers into a polym (B) 208, dehydration (C) 209, hydrolysis (D) 210, dehydration (E) none of the aboveExplanation / Answer
25.The correct answer is: B. 208,dehydration
Reason: Dehydration synthesis helps in combining one monomer with another.The number of reactions can be explained easily.For two monomers to join,2-1 =1 reaction would be required.So for 209 monomers ,it would be 209-1 = 208.
26.The correct answer is: C.Carboxyl
Reason: At terminal end of fatty acid is present carboxyl group.
27.The correct answer is:B.They spontaneously form bilayers in water.
Reason:Phospholipids do form bilayers in water.Also, they are made up of two fatty acids, a glycerol and a phosphate group.They contain two regions :one hydrophilic head region and other hydrophobic tail region.
