Why do some normal cells fail to respond to a chemical signal?
A) Chemical signals are only delivered to specific cells.
B) Some cells lack the necessary receptors.
C) Some cells are completely without receptors.
D) Some cells are completely without ligands.
E) Signal chemicals often break down before reaching a distant target.

Accepted Answer

Not all cells have the necessary receptors to respond to a specific chemical signal. This could be due to a variety of reasons, such as a developmental defect, genetic mutation, or simply not being the appropriate cell type to receive that particular signal.
