Hyla versicolor, commonly know as the Gray Tree Frog or the Eastern Gray Tree Frog, is an amphibian that is referred to as the “Chameleon of the Frog world” (Craighead, 2004, p.1) because of its ability to change colors. “This frog was once thought to be the same species as the Cope’s Gray Tree Frog”. They can only be distinguished by their calls and the fact that the Cope Gray Tree Frog is diploid while the Gray Tree Frog is tetraploid (NPWRC, 2004). The Gray Tree Frog is classified as follows:
Kingdom: Animalia
Phylum: Chordata
Class: Lissamphibia
Order: Anura
Family: Hylidae
Genus: Hyla
Species: H. versicolor
The Grey Tree Frog is about two inches in length. Its head is short and broad and its body corpulent (Dickerson, 1969). With a white belly, white rectangular spot under both of its eyes, yellowish orange markings on the inside of the hide legs and black blotches including one that looks like an irregular shaped star on its back this frog is very colorful and exotic looking. Depending on the environment and the stress level of the frog, its colors may change (Centralpets.com, 2004). H. versicolor may actually be any shade of brown, grey, green, or even light yellow or white. The temperature and the intensity of light also affect the frog’s colors. When there is bright light and a higher temperature perhaps it will be a yellowish white with almost no markings. When it’s dark and moist it may be a dark stone gray with dark markings (Dickerson, 1969).
The frog’s back is usually textured with coarse tubercles. Its fingers are thinly webbed while the hind foot is more developed. Large disks exist on the fingers and toes to assist with climbing and sticking to objects (Dickerson, 1969). The male and female Grey Tree Frogs are very similar. They are distinguished by the male having a dark underside of his throat. Also the females ears are smaller then the males (Dickerson, 1969).
The Gray Tree Frog can be found anywhere ranging from southern Ontario in Canada to the southern coast in the United States. Usually it is not found west of Texas or Manitoba, Canada. The can be found at Rice Creek Field Station. The best habitat is shallow water situated close to diverse stands of willows, oaks, and pines (Craighead, 2004, p. 2). The location of water and plenty of vegetation, which not only shades the forest but also covers the ground with broken brushwood, is what needed for the frog’s ultimate survival is.

“Little Frogs in a Ditch is a story about a self-concerned character named Lenny. Lenny loses his job at the laundry place, and instead of admitting to his mistakes he starts blaming his boss for him being fired. After being fired Lenny told his grandfather that he was going to become a salesman, and he starts selling wild pigeons. As crazy as it sounds, people actually fell for his false ad stating that they were homing pigeons. One of his customers, Mr. Lejeune, was trying to find a pet for his crippled grandson, Alvin; however, at this point we are all unaware that he is crippled. Lenny suckers him into buying one of his pigeons, and he tries to tell him how to train it to always come back to his yard. Lenny’s girlfriend, Annie, eventually

Although the Hippocampus spp. are placed into the same class as other organisms more traditionally viewed as fish, their morphology bears distinct differences in comparison to other bony fish. The various species belonging under the genus Hippocampus range in maximum size from 20 mm to 300 mm(Foster 8). Their physical appearance is distinct from other members of its class due to their "horse-like head, monkey-like tail, and kangaroo-like pouch."( Lourie et al 12) Morphologically, seahorses do not have scales like traditional fish, but rather posses bony plates covered by skin. The appearance of bony extrusions and skin ...

One rumor of what happened to the beloved nose of the Sphinx is that the great French military leader, Napoleon Bonaparte, used the Sphinx as target practice when he arrived in Egypt in 1789 CE. There are many flaws to this theory though, the first of which being that pictures drawn during the eighteenth century show the Sphinx without its nose, meaning that the nose was gone before Napoleon had arrived.another flaw with this theory is that Napoleon was a history fanatic, and would never destroy a great monument of history. Some people also blame the absence of the Sphinx’s nose on the Turkish, claiming they shot the nose off instead of Napoleon, but this has also been proven to be erroneous. The explanation given by researchers, which is the most reasonable out of all the claims, is that the Sphinx’s nose has been victim to erosion. Over the centuries, the Sphinx has been discovered, lost, discovered again, lost, and re-discovered a number of times. Each time the Sphinx had been excavated, it made the Sphinx subject to the wrath of nature’s storms and weather, causing the Sphinx to decay slowly. This process would be stalled once the Sphinx was completely submerged in sand, except the Sphinx never stayed buried forever. Every time the the Sphinx had been re-discovered, it was vulnerable to more erosion. Scientists and Egyptologists alike both state that erosion, given as many centuries as it has been, could have caused the destruction of the Great Sphinx’s
Irrefutable evidence that the employee poses a danger to others is information that the employer must act on immediately in order to protect others. However, if an employer has only a reasonable suspicion, the immediate supervisor should speak to the employee and determine if corrective or preventative action is necessary based on the foresee ability of harm. Both irrefutable evidence and reasonable suspicion are reasonable foreseeability of harm. Negligence law rests on the premise that members of society normally should behave in ways that avoid the creation of unreasonable risks of harm to others (Mallor, Barnes, Bowers, & Langvardt, 2013). Failure by an employer to take corrective or preventative action when an employee poses a danger to others may create a breach of duty and could result in a

When I researched the Sphinx I learned some other interesting things. I also discovered that nobody really knows a true fact. For example: Ancient Egyptian Art by Susan Hodge, states that the Sphinx was made out of sandstone. This was on page twenty two of the book. However, the website, “http://guardians.net/egypt/sphinx” states it was made out of bedrock. So really nobody knows what the Sphinx was built of.
The Centers for Disease Control and Prevention has listed immunizations as the number one greatest public health achievement in the 20th century. This attainment towards the goal of health and safety is a huge success for not only our country but from the global perspective as well. Immunizations help to prevent illness and death from vaccine-preventable diseases. The World Health Organization states that global vaccination coverage has remained consistent for the past few years; for example, the percentage of infants fully vaccinated against diphtheria-tetanus-pertussis has held secure at 83%. Programs for population-wide vaccinations have helped with the annihilation of polio in America since the late 1970’s, the eradication of smallpox, and the control of numerous other infectious diseases in the United States and other parts of the world.
Common core has been the program calling all the shots in most school systems in the United States. Since the year 2008, the common core standard testing has been sneaking its way into the school systems. The common core has brought up many different situations within the schools. One situation consists of determining the education level of students by using the same standardized test. Another situation is by requiring teachers to teach to a certain test, even though students do not fully learn what they are being taught. The government should not be able to evaluate students and teachers by one certain test. Attention must be brought up to how common core has changed our education system to the unproductive side, but then explain how our schooling systems can fix the problem that has been made. The common core can be fixed for the best, but the most fulfilling way to fix this problem is to get rid of the program altogether. The best results of students’ education can truly be viewed accurately once the common core is fully out of the school curriculum.
“To ensure all students are ready for success after high school, the Common Core State Standards establish clear, consistent guidelines for what every student should know and be able to do in math and English language arts from kindergarten through 12th grade” (What Parents Should Know, n.d.). Children are entering a world that is requiring more and more than before. Society is changing meaning education must change to keep up with society. “The standards were drafted by experts and teachers from across the country and are designed to ensure students are prepared for today’s entry-level careers, freshman-level college courses, and workforce training programs” (What Parents Should Know, n.d.). The focus is to allow students to think critically and be able to problem solve; skills needed in life. The Common Core State Standards are also providing ways for teachers to track each student’s progress as they grow and learn throughout the year. Common Core has many good qualities, but nothing is perfect. There will always be issues no matter the
(2014) exclaimed that why do 62 percent of parents think the Common Core is not perfect for their kids, despite it has fascinated some entrepreneurs such as Bill Gates and the secretary of education. In a case in point, parents should get more involved in the education of their children if they do not approve of measures being used. She agrees to the idea of a federal government using incentives to adopt their specific education program, but then again she only sees that parents complaining and not taking action. In another context, “parents have no choice about whether their kids will learn Common Core, no matter what school they put them in, if they want them to go to college, because the SAT and ACT are being redesigned to fit the new national program for education”. (Pullmann, J. 2014, September 24, p. 1). In fact, Porter (1989) states that the Common Core standards became as opposing to teachers and teaching occupation, and the tactics are not good strong enough for enabling teachers to be dependent. The teacher is often understood to be the planned without rules. Moreover, some voices against the criticism of the common core, they believe that it is meaningless because districts are still permitted to select which material goes out with stem the basis stated by the Common Core

The Polio epidemic that plagued the world in the 20th century has become contained to only a few developing countries. Since the discovery of the polio vaccine and the global initiative to eradicate polio the incidence of cases has decreased 99% worldwide. However the remaining 1% of the lingering polio cases in the world is proving to be difficult to eradicate. With the highlighted human qualities that have been so successful in the past need to be highlighted in the future in order to be successful. But these qualities are only as successful as the adaptive initiatives that allow these human qualities to thrive and succeed. Also with improved socio-economic conditions in the remaining effected developing countries that dream of a polio free world is possible.
