depletion of the ozone which in turn causes an excessive amount of ultraviolet, or UV, radiation to reach the earth. According to “Health and Environmental,” “A 10% reduction in ozone could lead to as much as a 15-20% increase in UV exposure depending on the biological process being considered.” This creates a lot of problems because an increase in UV radiation creates biological effects, or health effects, in a lot of organisms. The biological effects of excessive UV radiation due to ozone…

health will be impacted directly and indirectly due to the environmental changes that will occur with climate change. Ozone depletion occurs when manufactured chemicals such as chlorofluorocarbons reach the stratosphere; the UV radiation from the sun causes the release of chlorine atoms that react with the ozone. This chemical cycle causes ozone destruction that depletes the ozone layer. Ultimately, the chain reaction will affect the air quality, thus increasing respiratory problems. One…

Intro: Consider a math final in a stressful period in high school students’ careers. Due to some freak coincidence, every student in a class has forgotten their pencil--and, every student knows that the more pencils they have, the more they work they can write down for partial credit. A pile of used mechanical pencils sits unregulated in a corner. One student, Dylan, realizes that he can take one of those pencils and get a better grade than others in the class. In fact, he can take as many as he…

damage the human skin and lead to skin cancer. Ultraviolet radiation is composed of three types of rays; ultraviolet A, ultraviolet B, and ultraviolet C. Ultraviolet C is the most dangerous type of radiation, but does not penetrate the earth’s ozone layer unlike ultraviolet A and B (Medicinenet, 2013). Ultraviolet A stimulates melanin pigmentation, as it is able to reach deep into the dermis. Ultraviolet B is mainly absorbed by the epidermis and upper dermis, and is also responsible for…

that a SYN/ACK was received. With the 2 way handshake the server does not get any confirmation so the connection is closed. 6. When do we use Upward Multiplexing and Downward Multiplexing? The Upward Multiplexing strategy is used by the transport layer to group transport connection base on their destinations. By mapping the groups to the minimum number of network connection, this application is very beneficial especially when the network connections get…

Planarians are triploblastic acoelomates, meaning they have three tissue layers, ectoderm, mesoderm, and endoderm (Newmark and Alvarado, 2001). Their epidermal layer that surrounds the planarian is ciliated on the ventral surface (Newmark and Alvarado, 2001). Underneath the epidermal layer and the basal lamina, followed by a complex wall musculature that surrounds the body. The complex wall muscle is composed of the circular diagonal and muscle fibers (Newmark and Alvarado, 2001). The nervous…

Methods Column chromatography was set up using a 60 ml syringe clamped to a ring stand. The syringe was plugged using a small amount of cotton. An Erlenmeyer flask was placed underneath the column to collect any excess material. Eleven 20 ml vials were labeled numbers 1 through 11. Silica gel was measured to 42 ml using a graduated cylinder and then moved into a 150 ml beaker. A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. The slurry was stirred for…
