feedback+systems+activity

Copy and paste the following behaviours under the image of the relevant feedback system that is would effect. Make sure you write whether it would increase or decrease the levels.A particular behaviour may apply to more than one feedback system. I have done an example for you. Intially I would like you to only choose one statement, so that everyone has an opportunity. After wednesday, feel free to do as many as you wish or even move them around if you think they might be wrong.


 * Behaviours**


 * Drinking two litres of water in fifteen minutes
 * Riding an exercise bike 'flat out' for five minutes
 * Forgetting to take a water flask on a four-hour hike on a hot summer's day
 * Eating a piece of pavlova and drinking a chocolate thick shake
 * Participating in the 40-hour famine to raise money
 * Swimming in the ocean in winter for an hour without a wetsuit
 * Sleeping
 * Walking up a flight of stairs to the top of a 40-storey building


 * **Riding an exercise bike 'flat out' for five minutes**-increase in CO2 and decrease in O2




 * **Eating a piece of pavlova and drinking a chocolate thick shake** - increase in blood glucose levels. Therefore, a release of insulin.
 * **Participating in the 40-hour famine to raise money** - this will cause a decrease in glucose levels, thus, an increase of glucagon will be released and a decrease of secretion of insulin






 * Forgetting to take a water flask on a four-hour hike on a hot summer's day** - causes a decrease in water levels, therefore small volumes of concentrated urine would be produced.


 * Drinking two litres of water in fifteen minutes** - this will cause an increase in water levels, thus, large and dilute amounts of urine would be produced.




 * Swimming in the ocean in winter for an hour without a wetsuit** - this will cause a decrease in temperature levels, thus, hairs will become erect.
