The answer is liver, as they contain a nucleus and membrane-bound organelles. I hope this helps :-)
(Liver cells are examples of eukaryotic cells, so that should give you enough to answer your question.)

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
