What is the main function of motor organs in biology?

Release hormones into the bloodstream

Produce a response like motion (correct)

Activate gene expression within target cells

Receive and process electrical signals

How do endocrine glands release hormones into the bloodstream?

By triggering gene expression changes

Through activation of ion channels

What happens when a hormone binds to its specific receptor on a target cell's surface?

Activation of intracellular signaling pathways occurs

Gene expression changes are triggered

Protein synthesis is altered within the cell
