How Alcohol Is A Vasodilation
After seeing this data the two most effective look chemical at resisting energy was CaCl2 and LiCl. So we looked at the price of both of this chemical CaCl2 cost 6.55$ per 500g and LiCl cost 32.75$ per 500g because CaCl2 was substantially cheaper we decide to chose it to use in own hand warmer. We calculated that it would take 22g of CaCl2 to create a 20oC increase in temperature of 100ml of water. Some sources of error in this lab, would be heat escape from not be able to replace the lid of the calorement went adding chemical into it, inaccuracies in the balance, and not waiting of the proper time to recode the
First off the weather is so cold there that they have igloos as houses. That means that they can use their surrounding ice and snow to build a home that can stay there even through the summer. The Inuit can also build houses out of wood but it is very rare to see in a village because there are not a lot of trees in the arctic for them to cut down and build as houses, plus it takes more effort and work when they could just have an igloo and get other more important things done. Next thing that is different between the other two tribes is that the Inuit think that they are the most important barometer in the world because what happens in the world, like global changes, always happen there first. Therefore we can figure out what’s gonna happen to us in the next few years from the information based off of the arctic.
NIH Senior Health states that when people drink beer, wine and other kinds of drinks, the alcohol goes to the bloods team and then it spreads throughout the body. Then the alcohol moves through the metabolism. Metabolism is a one of the converting substances that our body usually uses. It affects the brain and other more when alcohol is break down into our body. On the other hand, when people drink alcohol, the concentration of alcohol in the blood goes to a peak and it decreases when metabolism makes the alcohol down.
The effects of alcohols on membrane have also been researched quite extensively. Previous studies have found that alcohols disrupt the structure of cell membranes (Goldstein, 1986). They have also found that ethanol has a stronger effect than other alcohols (Patra et al, 2005). From this research and literature the expected results of the experiment were to see an increase in membrane permeability, this result was observed. The study provides a brief insight into what kind of effects alcohol can have on cell membranes but it is limited.
Clothing was tailored to fit each individual person, which helped keep cold air out at the neck, waist, and wrists.” Their clothing was made from animal skin, and possibly from other parts of the animal. Depending on where you live, Americans usually wear jeans, and a winter coat. The Inuit have to wear heavier clothes in the winter time because they live in the cold tundra climate, so the Inuit have to make clothing the warmest they can with animal skins. Although it can get pretty cold in America we do not need clothing as warm as theirs, plus we can make clothing out of other materials like cotton, nylon, etc.

From this research and literature the expected results of the experiment were to see an increase in membrane permeability, this result was observed. The study provides a brief insight into what kind of effects alcohol can have on cell membranes but it is limited. The results can be used to understand but not explain more practical applications, like human cells for example. Conclusion

Artificial and natural selection are really the same process but one is driven by man and the other is driven by an organism's traits that allow them to survive and reproduce. Artificial selection is when mankind chooses certain traits in plants and animals and breeds to enhance that trait. Natural selection is also a process where traits are selected for, but that selection is based upon a trait that gives the organism a mating or survival advantage and this allows them to pass down the traits they possess. Artifical Selection Doesn't Necessarily Make a Species More Fit for Survival Since humans formed cultures based upon agricultural and the raising of animals for food, man has gradually understood that he could selectively breed organisms in order to enhance certain traits that were beneficial for man. However, such traits may not necessarily be beneficial for a species fitness in nature.

• Warming (vasoconstriction): when cold the body protects itself by moving blood from the extremities to the vital organs, ensuring that they are kept warm. With the blood diverted to the major organs the capillaries and pores narrow, the skin appears pale and heat loss is prevented. The erector pili muscles contract, causing body hair to stand on end, trapping air against the surface of the skin, which is then warmed by body heat. Shivering occurs, caused by rapid and repeated muscle contractions which work to raise body temperature.
