HI mates... what is meant by response to stimulae and give 3 ex..
Answers
Our environment is constantly changing, and in order for us and other living things to survive those changes, we must be able to respond to them. Any detectable change in the environment is called a stimulus. Usually, a stimulus is a product of change in an energy source or force, such as light, or sound, or heat. As humans, we detect and respond to stimulus in order to survive.
For example, if you walk outside on a very sunny day, your pupils will constrict to protect your eye from taking in too much light and being damaged. Your body reacts to the stimulus (the light) to protect you. Let's take a closer look at how a stimulus is detected
Response means any change in an organism resulting due to the stimulus.
Examples:
- withdrawal of hand on touching a hot plate.
- pain in the eye if something falls into it.
- seeing green light turning red and then crossing the road.
