Most of us have enjoyed "cruising" sometime in our lives. For many, it was one of our favorite pastimes. If you lived in the "American Graffiti" era, it was the in thing of to do. I remember when cruising was a popular activity on Main Street in Mesa for many years, until it was banned a few years ago. Now the controversy is over whether to ban cruising on Central Avenue in Phoenix. City officials are trying to reroute the weekend riders to Washington and Jefferson streets. Although cruising may be enjoyable to quite a few teenagers, there is no positive purpose for it. The negative effects of cruising outweigh the reasons for it by far. Cruising should be banned altogether because cruisers have proven to be very loud, dangerous, and a contributor to our pollution problem.
I have sympathy for those who live near Central Avenue. The weekends are very noisy in this vicinity. For example, some of the stereos blasting away could accommodate a rock concert. The base volume coming out of these speakers is felt in your heart as you drive along Central...
Echo Park, one of Los Angeles’s most well-known neighborhoods, was once associated with gang violence in the 80’s and 90’s. The crime rate in the area was to the point that many people would not dare being caught walking out after dark. Nowadays, people do not fear walking in the streets of Echo Park after dark. This new sense of safety in Echo park can be contributed to its nightlife scene characterized by Indie music venues and trendy bars. You may ask yourself how this change came about?
What does it mean to ban a book? A banned book is one that has been removed from the shelves of a library, bookstore, or classroom because of its controversial content. (About.com) Before banning, a book must be challenged. A challenge is an attempt to remove or restrict materials, based upon the objections of a person or group. (About Banned And Challenged Books) A book is challenged when a person or group dislikes some of its content, and wishes to have it removed. Often times, it is banned for obscenities and is considered unsuited for the set age group, or any age group.
In the late adulthood life of Roseanne she began being an example of the peripheral leisure activities in which later contracted to core leisure activities not only due to age but also to social/emotional effects. After passing through a phase of regression her activities expanded and she slightly engaged in the quality of being active.
Homeostasis can be defined as the ability or tendency of an organism to maintain its stability. If an organism does not maintain homeostasis it will die. Dynamic equilibrium is what happens when the organism adjusts to maintain a constantly balanced internal environment. Dynamic equilibrium is caused by the organs inside humans and other animals fluctuating between increasing or decreasing their function to maintain homeostasis. The way these organs react is known as a response, and the response is reacting to a stimulus. A stimulus is something that affects the way organisms function. The body maintains homeostasis by working with the nervous system. The nervous system releases hormones which signal the cells or organs to decrease or increase their function.
The skin exhausts excess salt, water and urea from blood in the form of sweat on to its surface. Besides the removal of waste, the skin is also pertinent to homeostasis, as sweat helps maintain temperature.

Investigating the Resistance of a Wire The aim of this investigation is to see how the length of a wire affects its resistance. Background knowledge To make current flow through a conductor, there must be a potential difference (voltage) across it. As the current continues to flow there are certain factors which increase the resistance; Length of wire: as the length increases there will be a higher percentage of fixed atoms, therefore the electrons carrying the charge will collide more frequently, increasing the resistance Surface Area of wire- As you increase the surface area of a wire the resistance will decrease because the electrons will be able to travel by many different routes making the conduction easier. Type of conductor- If the wire is a good conductor of electricity then the resistance will be less because the electrons are able to flow through the wire avoiding as many collisions with the positive protons.
School System As mentioned previously, the school system has a perceived obligation to discipline students in an attempt to protect the safety of all staff and students, to preserve the decorum of the school, and also to develop character in students (Kajs, 2006). It is these three notions, along with the public’s perception of the rising issue of youth crime, and federal and provincial legislation that led to the implementation of zero tolerance policies. There are arguably three stages of the zero tolerance policies: there must be a perceived issue by the public, which creates a moral panic and leads to the government taking action to calm the situation by creating legislation and lastly, the school board implementing the regulations and changes. A qualitative study was conducted by Daniel and Bondy (2008) concerning several school’s opinions on zero tolerance policies and the Safe Schools Act.
It is also relevant to know of Ohm’s Law, which states that the current through a metallic conductor (e.g. wire) at a constant temperature is proportional to the potential difference (voltage). Therefore V ¸ I is constant. This means that the resistance of a metallic conductor is constant providing that the temperature also remains constant. Furthermore, the resistance of a metal increases as its temperature increases. This is because at higher temperatures, the particles of the conductor are moving around more quickly, thus increasing the likelihood of collisions with the free electrons.
The encrine sweat glands are located under the skin and are responsible for secreting sweat. Where as, the hair on our skin prevents heat from being trapped by a layer of still air as a result of arrector pili muscles under the skin relaxing. This will only occur if the environmental temperature is above core body temperature as a response to losing heat and therefore cooling the body down. Also in these conditions the human body undergoes what is known as arteriolar vasodilation. Arteriolar vasodilation is when the cell walls of the arteries are relaxed compared to cold conditions when they are restricted. As a result of the cell walls relaxing the blood flow around your body also increases redirecting blood through superficial capillaries where covention and conduction occur to reduce the body temperature. In contrast, when the body experiences cold conditions we can assume that the opposite would occur to the hot conditions. An example of this assumption is that in hot conditions when we sweat heaps, in cold connditions sweat production is decreased. Another example is the erector pili muscles under the skin relax in hot conditions where as in the cold conditions they contract, making the hair follicle stand upright. As a result to
Many restaurant and bar owners think that the ban will decrease business, but a counter-argument to this is that only twenty percent of the city's population are smokers, and when the smoking ban is in place, the other eighty percent will go out to bars and restaurants, dramatically increasing business. There are many different opposing arguments to banning smoking, and the debate will probably never end. Smoking should be banned in public places because, although some may argue that it infringes on their freedom, smoking is replete with harmful substances. People should be able to frequent bars and restaurants without the fear of experiencing an asthma attack or developing lung disease. Everyone deserves the freedom to live and breathe without restriction.
Resistance of a Wire Introduction Resistance is the opposition a material offers to the flow of electricity. The electrical resistance of an object is not only by what material it's made of, but also by its shape. A very thin copper wire has more resistance than a thick copper wire of the same length. A very long copper wire has more resistance than a short one of the same thickness.
Homeostasis is used by every organism to be able to survive in a certain environment. This happens because the organism needs to adapt to the certain conditions that the environment is exposing, but if the organism fails to adapt it may can lead to death. The system sends alerts through the nervous, electrical circuits, and hormonal system.
