Which is NOT a Basic Method of Cell-To-Cell Communication

Question

Which is NOT a basic method of cell-to-cell communication?
A) cytoplasmic transfer of signals
B) contact-dependent signals
C) diffused chemical signals
D) nerve and blood-transported signals
E) mechanical signals

Accepted Answer

Cell-to-cell communication typically involves cytoplasmic transfer of signals, contact-dependent signals, diffused chemical signals, and nerve and blood-transported signals. Mechanical signals, while they can affect cells, are not considered a basic method of direct cell-to-cell communication in the same way as the other options listed.
