Detailed explanation-1: -Endocrine signaling is an example of long distance communication between hormone producing cells, tissues and glands and cells that express hormone receptor molecules.

Detailed explanation-2: -In endocrine signaling, the signaling molecules (hormones) are secreted by specialized endocrine cells and carried through the circulation to act on target cells at distant body sites.

Detailed explanation-3: -Endocrine signaling occurs between distant cells and is mediated by hormones released from specific endocrine cells that travel to target cells, producing a slower, long-lasting response.

Detailed explanation-4: -Answer and Explanation: Insulin signaling is an example of endocrine signaling. Insulin signaling is an important form of cell signaling for the maintenance of homeostatic blood sugar levels.
