For an example, if a seal didn't have any blubber then it would not be able to survive because the body would not be the correct temperature for it to live. Homeostasis means to maintain a certain temperature for an organism to survive in certain conditions. In the experiment homeostasis was the vegetable shortening keeping warmth in the bag when it was in the ice water. The vegetable shortening however did not maintain full homeostasis because the temperature in the bag was 19 degrees on average after being taken out of the water. The experiment showed that it was a negative feedback because it was showing that the blubber was responding to the cold water by blocking the cold temperature out and maintaining homeostasis. The blubber in the experiment showed stability because it kept a temperature close to the starting temperature which is homeostasis. The change which shows what the difference was in a of the temperature was 4 degrees which is how much the temperature dropped. The overall structure shows that the vegetable shortening (blubber) worked pretty good considering the temperature only dropped 4 degrees in 4 degree water. The substructure of the experiment was also decent because the (blubber) helped maintain the temperature inside of the bag to within 4 degrees of the starting temperature in the
