Questions and Answers

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
  • By secreting them into the bloodstream (correct)
  • By diffusing them directly to target cells
  • 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
