Living things (such as plants and animals) |
Strive to maintain balance through the process of homeostasis |
By responding to feedback mechanisms |
Let's practice. Below is a list of feedback mechanisms. Predict how the organism will respond in an effort to maintain homeostasis. Click on Check Your Answer to see if you are correct.
| A cook touches a hot stove without an oven mitt. In order to maintain homeostasis, what happens next? |  |
|
| The hand is burned because it takes time for the nerves to respond to the pain of the heat. Interactive popup. Assistance may be required. Oops 
|
Before the pain is registered by the cook's brain, the nerves cause the hand to retract. Interactive popup. Assistance may be required. Correct!
|
|
| A dog with sensitive eyes goes out into the sun. In order to maintain homeostasis, what happens next? |  |
|
| The dog's pupils become smaller to protect the eye from damage caused by bright light. Interactive popup. Assistance may be required. Correct!
|
The dog's pupils dilate to allow the light to be spread throughout the eye. Interactive popup. Assistance may be required. No
|
|
| A plant is dry and needs water. In order to maintain homeostasis, what happens next? |  |
|
| The plant roots grow deeper and wider to seek out a source of water. Interactive popup. Assistance may be required. Correct!
|
The plant roots shrink in order to prevent water loss. Interactive popup. Assistance may be required. Sorry
|
|
| Wind blows sand into your eye. In order to maintain homeostasis, what happens next? |  |
|
| The eye becomes blood shot in order to make the sand more visible and easier to remove. Interactive popup. Assistance may be required. Oops
|
The eye blinks and tears in an attempt to remove the sand. Interactive popup. Assistance may be required. Interactive popup. Assistance may be required. Correct!
