HVWilson Worked with Sponges to Gain Some Insight into Exactly

Multiple Choice

H.V.Wilson worked with sponges to gain some insight into exactly what was responsible for holding adjacent cells together.He exposed two species of differently pigmented sponges to a chemical that disrupted the cell-cell interaction.The cells of the sponges dissociated.Wilson mixed the cells of the two species and removed the chemical that caused the cells to dissociate.Wilson found the sponges reassembled into two separate species.The cells from one species did not interact or form associations with the cells of the other species.How do you explain the results of Wilson's experiments?

A) There are enzymes involved in the assembly of the sponge organism,and the two different species had two different enzymes functioning in reassembly.
B) The disassembled cells formed bonds with any of the cells in the mixture.However,once the organism was completely assembled,an enzyme changed all cells to the same pigment.
C) The molecules responsible for cell-cell adhesion were different in the two different species of sponge.
D) One cell functions as the nucleus for each organism,attracting only cells of the same pigment.
