  Human Variation: Cold Weather 1.Colder weather affects homeostasis in humans by lowering internal body temperature past 94 degrees Fahrenheit which is called hypothermia. Since internal heat is not being produced quick enough the body may start to shiver or speed up the metabolic rate, both ways of increasing heat production. This is usually not as efficient  because it requires the individual to increase their caloric intake. The other negative effect that the cold has on the body is through heat retention, not expulsion. Vasoconstriction reduces the blood flow near the body’s surface so the internal organs can retain enough heat to function. This can cause frostbite in the outer extremities of the body, in which the outer skin and tissue start to freeze and form ice crystals in the body. This limits the mobility of fingers and toes and in worst cases the tissue can die and those appendages need to be amputated. 2. Short-term adaptation: Shivering Shivering is a short term response

  One Person Charades  The first portion of this language assignment required that no written or spoken language would be used. When I was first reading the assignment I thought it was going to be a very challenging thing to keep a conversation going for 15 minutes, so I spoke in a group environment with my family instead. My sister likened the assignment to the game charades which I was basically doing for the entire duration. The main reason that this first part was difficult to me was because I did not know how to express my thoughts and would instead either dumb it down or just not respond because I physically could not get my point across. Also I found myself listening to the other people talk most of the time because I did not want to ruin the flow of conversation that they had going. I did notice myself trying to exaggerate my movements as much as possible and tapping the specific person on the shoulder if I had a question for them or reenacting what I was thinking like charades
