The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms. In multicellular organisms, cells send and receive chemical messages constantly to coordinate the actions of distant organs, tissues, and cells. Cells can receive a message, transfer the information across the plasma membrane, and then produce changes within the cell in response to the message. Single-celled organisms, like yeast and bacteria, communicate with each other to aid in mating and coordination. Cellular communication has developed as a means to communicate with the environment, produce biological changes, and, if necessary, ensure survival.
Many think that birds evolved from dinosaurs, they both have hollow bones, recent studies show that some Dinosaurs had feathers. if you were to compare the form of a Dinosaur to a chicken you would see that they walk and stand like each other. Also, the Genes show that they might have a distant relative. I hope this helps
If you have just eaten a large meal, it is likely that your liver is actively monitoring the amount of glucose and glycogen in the body and helping to turn on or off the hunger. The liver regulates the blood glucose by storing and producing sugar when necessary. During a meal, the liver will store sugar, or glucose, in form of glycogen for a later time when it is required in the body. The high levels of insulin and decreased levels of glucagon during a meal promotes the storage of glucose as glycogen.
