Question

Which of the following is an example of chemical coordination?

• A. When you touch a hot plate, you withdraw your hand immediately.
• B. If someone runs in front of the car you're driving, you suddenly apply the brake.
• C. If you are attacked by a bull, you try to run away from it.
• D. Playing a fast game like tennis.

Answer 1

The correct option is C If you are attacked by a bull, you try to run away from it.

If you are attacked by a bull, you trying to run away from it is considered as an example of chemical coordination because this coordination is brought about through the secretion of chemical messengers known as hormones, in this case, adrenaline. When you are under attack, adrenaline is released into your blood to give you extra energy and strength to run. All the other options are examples of nervous coordination.
