When a snake makes noise as it comes near a jerboa to hunt it: ▌The jerboa's sharp sense of hearing and its strong legs for jumping work together with its nervous system to help it survive. ▌The whole response process of the jerboa running away from danger occurs in less than one second. ▌The time taken by a jerboa to react to danger is known as the "reaction time". Reaction time It is the time taken by the body of a living organism to respond and react to different information from the environment (such as danger). How does the jerboa respond to danger compared to a human? ▌ Both human and jerboa avoid danger by relying on sensory receptors, nerves and a brain to sense and communicate messages. ▌Both human and jerboa move quickly away from danger for their safety. بالتوفيق مستر احمد الباشا
