Cells in a large multicellular organism communicate with each other by chemical signals. These signals are passed from one cell

Answer:

Cells within a large multicellular organism communicate through chemical signals. These signals are relayed from one cell to another. A cell must have a receptor for that chemical to interpret and respond to a signal.

Explanation:

To initiate a physiological response, all body cells possess specific proteins known as receptors. These receptors are essential for detecting chemical signals and eliciting responses. Different receptors are tailored for various chemical signals; for instance, a dopamine receptor engages with dopamine molecules, whereas an insulin receptor specifically binds to insulin molecules. Additionally, certain cells may also respond to mechanical signals.
