Sink or swim 50 years back most everyone heard the story of how humans had evolved over time. It was claimed that our ancestors, apes, had been separated between jungle and desert. Comparing physical traits of both apes and humans, there is a dramatic difference. Apes on four legs, covered in layers of fur… Then there are the humans, standing tall upon two legs, having no fur. The original theory is that when our ancestors parted in two opposite environments they had simply adapted different…

Skin Portion: Yhara Barba The skin of a human is an elastic covering that acts a protects the body . The skin has many functions that greatly benefit the body. The functions are Protection, sence of touch, and it controls temperfature. Protection: The skin helps to keep bacteria and dangerous stuff out of our body, like germs and dirt that can cause infection. Adding on it helps retain water. Sence of Touch: The skin is hoem of one of our five senses: touch. Within our skin thre are thousands…

Another benefit of double glazing is that it can reduce sound transmission. This means that you won’t be able to hear the buzz and din of noises outside as loudly. In Cheshire, PVCU double glazing is something to consider as it not only acts as an insulator but also raises the value of your building. It is essential for protection against weather and the elements as heat will take longer…

Myelin is imperative for the functioning of adequate conduction velocity speed in axons. Myelin is made of water, lipids and proteins and appears white in color. This combination of lipids and proteins form a whitish protective cover or sheath over the axon of numerous nerve fibers. This sheath covering the axon speeds up the impulses that are being conducted, which is important in the transmission of impulses in our body. Without myelin speeding up conduction, the impulses would decelerate.…

To the Alfred E. Smith High School Administration, Faculty and Staff: Environmental sustainability is an ongoing issue in United States society. It is one of those matters that are significant but really isn’t seen to be as critical to who live in the society. Everyday companies dispose waste in many harmful ways that affect the environment. These environments are homes to various animals that are being demolished by the ignorance of people. It isn’t only the major companies contributing to the…

Physics as a Discourse Community Discourse communities, or groups of people who share the similar interests, exist everywhere, but they become more obvious in college because each major is its own academic discourse community. In “Discourse Communities,” Schmidt mentions that it is more common to see students who are part of the same academic discourse community spending most of their time together because they “focus [their] attention on the same issues and things” (1). This is due to the…

minutes it lost 21.25 millimeters. Finally, when three hours passed 34 millimeters of water was melted from the ice cube. After thirty minutes, the house insulation became 50°c and when one hour passed the temperature was 42 °c. Out of the three insulators I used the best one was the Styrofoam. When thirty minutes passed only 0.5 millimeters of water melted. One hour passed and 1.25 millimeters melted. In an hour and a half 10 millimeters melted and in two hours 16 millimeters melted. Finally,…

For much of the past century (or longer), a substance known as asbestos was used quite frequently in a variety of construction applications. Not only was the material found to be durable and versatile, it was also a very cost-effective solution, and so its use was quite prolific in the installation of insulation, floors, ceilings, etc. Today we know that asbestos poses a very serious health concern, and so it is no longer used in modern day construction applications. Unfortunately, this material…

asbestos. This was not a common disease, until more industries and mining plantations started to occur. Some jobs are more likely to give a person mesothelioma than other such as shipyard worker, construction worker, chemical plantation worker, insulators, auto mechanics, and industrial workers. Mesothelioma has many symptoms and effects but it all…
