Study the scenarios below. Choose THREE of the scenarios that demonstrate examples of visual communication.
Scenario A: Young chimpanzees express the "fear grin" to show submission to the dominant male chimpanzee in the troop.
Scenario B: Rattlesnakes will rattle their tails to warn their predators that attacking the snake will come with a poisonous bite.
Scenario C: Wolf packs hunt in groups to enhance their ability to survive by using complex movements to surround their prey.
Scenario D: Pheromones are secreted from special glands that allow for communication among organisms. Some examples of pheromones are urine, sweat, and even feces. Dogs use pheromones and other auditory communication to warn other animals to stay away.
Scenario E: A puffer fish gulps large amounts of water to make itself blow up large and round in the hopes of evading predators. The spines on a puffer fish are also toxic if ingested.
