Detailed explanation-1: -Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

Detailed explanation-2: -Organisms continuously detect and process physical and chemical signals from their external and internal world, and they monitor their interaction with the environment.

Detailed explanation-3: -Expert-Verified Answer. Explanation: The process by which cells interact with other cells in their body or with the outside world is known as cell signaling.

Detailed explanation-4: -Chemical signaling via the production of small molecules such as hormones has been studied in detail in higher organisms. These molecules have important functions in maintaining physiological homeostasis as well as allowing organisms to respond to external insults.
