Detailed explanation-1: -What is an organic compound that is made by glands in the body ( pituitary, thyroid, etc.) that is used in long distance communication between cells? Ligand-receptor complexes are most often formed in cell communication pathways in which participating cells are in direct contact.
Detailed explanation-2: -Direct-Contact Signaling: Gap junctions-tiny channels that connect neighboring cells-are found in plants and animals. These gap junctions are full of water and allow small signaling molecules to travel across the channel. This is cell signaling through direct contact.
Detailed explanation-3: -Explain how cells communicate with one another over short and long distances. Cells communicate over short distances by using local regulators that target cells in the vicinity of the signal-emitting cell – a. Signals released by one cell type can travel long distances to target cells of another cell type.
Detailed explanation-4: -How does a hormone qualify as a long-distance signaling example? In endocrine signaling (hormonal signaling in animals), hormone molecules are released by specialized cells, which travel to other parts of the body through the circulatory system to reach target cells that recognize and respond to the hormones.
Detailed explanation-5: -When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send.
