In This Part :
How do all parts of a jerboa's body work together to avoid danger?
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.
