Fall Leaf Colors by Tree Species

Certain broadleaf trees can be uniquely identified by their brilliant fall leaf color. In some cases, a trees common name is derived from its primary autumn leaf color, such as red maple and yellow poplar. The most common leaf colors of fall are red, yellow, and orange. Some tree species can express several of these colors simultaneously as the season progresses. How Fall Leaf Color Develops All leaves start out in summer as green. This is because of the presence of a group of green pigments known as chlorophyll. When these green pigments are abundant in the leafs cells during the growing season, they mask the color of any other pigments that may be present in the leaf. Chlorophyll in the leaves is the trees main means of producing nutrients during the summer. But with autumn comes the destruction of chlorophyll. This demise of the green pigments allows other, previously masked colors to come forward. Those unmasked fall colors quickly become markers for individual deciduous tree species. The two other pigments present in leaves are: Carotenoid  (produces yellow, orange, and brown)Anthocyanin  (produces red) Trees With Red Leaves Red is produced by warm, sunny fall days and cool fall nights. Leftover food in the leaf is transformed into the color red through anthocyanin pigments. These red pigments also color cranberries, red apples, blueberries, cherries, strawberries, and plums. Some maples,  sweetgum, and oaks have red fall leaves. Dogwoods, black tupelo trees, sourwood trees, persimmons, and some sassafras trees also have red leaves. Yellow and Orange Shades Chlorophyll is destroyed with the onset of autumnal conditions, which reveals the orange and yellow leaf colors, or carotenoid pigments. Deep orange is a combination of the red and yellow color-making process. These yellow and orange pigments also color carrots, corn, canaries, and daffodils, as well as egg yolks, rutabagas, buttercups, and bananas. Hickory, ash, some maples, the yellow poplar (tulip tree), some oaks (white, chestnut, bear), some sassafras, some sweetgum, beech, birch, and sycamore trees have yellow leaves in the fall. Weathers Effect Some years see more brilliant color displays than others. It all depends on weather conditions. Temperature, the amount of sunlight and how much rain fell all are contributing factors in color intensity and in how long theyll remain. Low temperatures, but above freezing, are good for reds in maples, but an early frost can hurt a bright red color, according to SUNY College of Environmental Science and Forestry. Overcast days tend to make all colors more intense. Peak Viewing The United States and Canada produce a variety of fall foliage colors which has created a tourism industry. Here are peak viewing times in the United States: Late September/ Early October: New England, upper Minnesota/Wisconsin and the Upper Peninsula of Michigan, Rocky MountainsMid-, Late October: Upper MidwestNovember: Southwest, Southeast Some Stay Green Not all broadleaf trees change colors and drop their leaves in the fall. Found mostly in southern climates, some evergreens broadleaf trees can survive tough winters. Magnolias, some oaks, and myrtles are among them.

Effects Of Homeschooling - 763 Words

As civilization has changed, so has the school system. Consequently, the impact that educational environments have had on students have changed. While the traditional-school approach is massively popular, homeschooling can solve many of the problems that the current educational system brings about. Students who grow up in a homeschooled environment are allowed flexibility around their learning curves and decreased likelihood of both pornographic and violent exposure. Traditional-school environments constrict students to specific learning paces that may not fit their individual needs. This lack of flexibility can negatively affect students’ academic careers. In fact, â€Å"homeschooled students achieved higher standardized test scores†¦show more content†¦Thus, it is important that those educated at home actively seek out personal interaction in other areas to develop their social skills. Growing up in a homeschooled environment can decrease the likelihood of pornographic exposure. Considering pornography has become immensely more accessible due to smartphones, it is far more likely in today’s society for one to be exposed to it by surrounding students. While one may not necessarily want to view it at first, the desire to become part of the crowd can be compelling. Thus, traditional-school environments present the opportunity for innocent kids to be introduced to pornography by the students around them who have easy access to the websites. On the contrary, homeschooling provides students with an environment that can generally increase accountability when it comes to what they view online. Spending time at home rather than being forced into a school allows students to more carefully select their friends and can limit the people who influence them. Consequently, the likelihood of being negatively influenced by their peers is greatly decreased. However, wh en homeschoolers hit college there can be a major culture shock considering pornography is ever increasing in our society.

Forensic Science And The Scientific Examination Of Evidence

The scientific examination of evidence in criminal cases found in a crime scene is called forensic science. Forensic scientists use the same technology, tools and methods used by other scientists doing other types of research, including microscopes, computers, and lasers. As forensic science has advanced over the years, so has the ability to gather evidence and solve crimes. At crime scenes, lasers provide lighting to track blood sample that not visible to the naked eye. Forensic imaging technology is technology that lets the first responding local police department or crime scene investigators immediately send a photo or fingerprint image to a central database for identification. Computers can enhance pictures taken by a camera and use features like the facial recognition software to clearly identify blurred images. Lasers can also vaporize small portions of paint specimens to determine the exact paint used on a car in a hit-and- run case. Although this science has been used for ye ars, wrongful convictions have brought to the attention that forensic science has been faulty for decades. The chilling truth is that forensic science has contributed to convicting innocent people over the decades and will continue to do so if the normality continues.

Pragmatic English versus Perfect English

Question: Discuss about the Pragmatic English versus Perfect English. Answer: Introduction: Being a person of an Arabic origin and having a belief that I can speak a perfect English I found it astonishing when I am reminded that my English is pragmatic. This ascription results from the ideology that only Native English speakers can understand and speak the language fluently. Out of this perception, pragmatic language is only embraced within the organizational context and it if is attributable to the non-native English speaker only. As Bailey, Canagarajah, Lanc, Powers (2016) puts it, being non-native English you have to acquire perfect English to qualify for certain positions. For example, Bailey, Canagarajah, Lanc, Powers in their article noted that Violet found that pragmatic English was restricted within the geographical scale and was acceptable in the workplace. However, the use of perfect English was restricted within the global scale. Additionally, there is a perception that for someone to have the successful career he or she must qualify as perfect English speaker. The attitude mentioned above discredits the non-native English speaker who qualifies as perfect English speakers but is still being referred to as pragmatic English speakers. For example, having studied and practiced English language for several years does not qualify me as perfect English speaker. I cannot solely argue that I am a perfect language speaker because of the social context where I was practicing my career. However, the perception that perfect English is a global language has influences many of my fellow citizens to acquire it. Having stayed with Native English speakers in Australia, I have developed a negative attitude towards my experience with them. Perfect English entails understanding the little details that the pragmatic English language speakers do not know. This impression has made it difficult for me to associate with the native language speakers. This attitude can be attributed to Bailey, Canagarajah, Lanc, Powers (2016) argument that there is a psychological barrier that exists between the pragmatic and perfect English speakers.
