PLANTS AVOID SUNBURN In chapter 5, we learned about one of the most important roles in plants, which is photosynthesis. Photosynthesis is the process by which plants,algae, and some microorganisms harness solar energy and convert it into chemical energy, this is done through pigments in plant cells. These pigments have distinct colors because some absorb more wavelengths then others. For example, carotenoids, these accessoery pigments reflect longer wavelengths of light, making them appear red, orange,or yellow. Carotenoids perform two major functions in the process of photosynthesis. One purpose is to serve as excessory light pigment and the other purpose to serve is to protect the pigments from the photo distructive reaction of oxygen. There was a couple articles breaking down this process. I found a popular article published July 19, 2006 that has no author but the source was Arizona State University. This same institution offered a scientific article written by Iris Visoly-Fisher, Kayvon Daie, Yuichi Terazono, Christian Herrero, Fernando Fango Luis Oterom Edgardo Durantini, Juana J. Silber, Leonides Sereno, Devens Gust, Thomas A. Moore, Ana L. Moore, and Stuart M. Lindsay published in June 6, 2006. This article was most likely written for scientists or college grads majoring In the field because it was more into depth and was pubished on www.pnas.org[->0]. While the popular article is mostly intended for high school or junior high students as its published on pysc.org[->1], a website explaining this process in a simpler form. Both articles helped me understand this topic greatly. The goal of the scientific article if to understand one of the roles of the car in photosynthesis and to explore the role as gatable electronic components. As for the popular article the goal was to explain how biomolecules called carotenoids participate in this process of

On the other hand, the type of skin cancer which is least common is melanoma, but it has been categorized as the most dangerous. The other skin cancer type which is considerably common is squamous cell carcinoma. Both the basal cell carcinoma and squamous cell carcinoma are commonly termed as nonmelanoma. Other least common nonmelanoma cancers of skin are cutaneous lymphoma, Kaposi’s sarcoma alongside merkel cell carcinoma. In most cases, melanoma originates from the skin surfaces which are directly exposed to the sun. In addition, melanoma has the capability of spreading very quickly all over the body unlike nonmelanoma. (Kantor ¶ 1, 2009).

...An introduction to climate change Section 1: What is climate change? Recent climate history and future projections Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. What is weather? At every moment at any spot of the world, the troposphere (the inner layer of atmosphere which contains earth’s most of the air) has a particular set of physical properties – i. Temperature, ii. air-pressure, iii. humidity, iv. precipitation, v. sun-shine, vi. wind direction and speed. These short term properties of atmosphere at a particular place and time are weather. What is Climate? Climate is a region’s general pattern of atmospheric or weather conditions over a long period. Average temperature and average precipitation are two main factors determining a region’s climate. What is climate? • The long-term average of a region’s weather: – Average rainfall. – Average hours of sunshine. – Average temperature. • Climate versus weather: – Weather describes whatever is happening outdoors in a given place at a given time. – Climate describes the total of all weather occurring over a period of years in a given place. – Climate tells us what it's usually like in the place where you live at a certain time of year.
