Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.

Question: Many molecules are moved through the body by?
Answer:<u> The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules.

Answer:
Lophotrochozoans (it is a protostome)
Explanation:
Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.
