1. 1.) Explain why homeostasis is important to your body's functioning.

Homeostasis is important to our body's functioning because homeostasis is what keeps our body at a stable temperature (37 degrees Celsius) for example if our bodies were at a very high temperature our cells would denature on the other hand if the temperature was to be extremely cold our cells would freeze. In conclusion 37 degrees is the "perfect" temperature since the body is not too hot nor too cold, just like the Earth when compared to the distance between itself and the sun. If the Earth was too close the whole planet would be a vast bare and dry land with no life whatsoever since the temperature is too high, on the other hand if the Earth were to be too far away the planet itself would be cold and dry hence temperature would too cold for life to grow.

2.) Give three examples of ways your skin helps maintain homeostasis in your body.

The examples used to support the idea of skin maintaining homeostasis in our bodies are:

• Provides physical barrier between the exterior and internal part of the body, not allowing any dirt or microorganisms whatsoever to enter the body. So no wind chill or any hot things should make contact with the inner body.
• The skin when under cold conditions contracts so that the body doesn't lose any heat. Since under these types of conditions heat is essential to survive.
• When under hot conditions your body sweats-it dehydrates. To be able to cool down your body. To have a better understanding of this concept one has to know that when evaporation takes place a chemical reaction takes place. Normally there is a surface beneath a liquid for example: your skin and your sweat. The wind is blown against your sweat so the skin loses energy but this energy happens to be heat energy hence cooling you down.

3. Explain one way that your body maintains a constant temperature while outside on a cold day.

When it's a cold day your body shivers since the muscles inside your body have contracted hence releasing heat energy to stabilize the body temperature.
