techniques: the reaction that a predator is nearby, and the second is that they have been place in a life danger, so their instinct tells them to escape.
Scientists have created 4 various experiments on humans with a mixture of putrescine, water and ammonia, just to prove that human’s reactions and behavior are not any various than these of the animals.
Vigilance
The 1st experiment, exactly where participants had been tested to the scent of putrescine, as they had been exposed to the scent of it and tested out their vigilance. The outcomes showed that the participants who had been exposed to the scent of putrescine showed a lot more vigilance than these who had been exposed to ammonia and water.
