The tropical savanna is one particular biome with many interesting and defying aspects. The natural characteristics and animal and plant adaptions are what make the tropical savanna one of the most incredible biomes that is found on earth. The characteristics of the savanna can allow it to be easily identified from the many other biomes. The majority of it is filled with high grass and a conventional tree that provides shade for the animals (Wilkes 64-65). "The World Around Us." Your World A…

Depending on the temperature, the wax is harder for colder temperatures and softer for warmer temperatures. The various hardness shifts the melting point of the wax. A harder, denser wax will have a higher melting point, (upwards of 140 degrees Celsius) and a soft wax will have a much lower melting point. Another physical change that is observed when waxing skis is the transfer from a unified form solid to a liquid that has no definite shape. These physical properties that are observed help…

A culture of different species was brought to the lab to be analyzed in order to identify the pathogen causing disease. The goal of this lab was to be able to identify the unknown pathogen, match the patient to the bacterium, and being able to identify the disease it causes. At the beginning of class, the TA handed each student an agar plate containing some unknown bacteria, each one was numbered. Mine was number 14. The teacher then asked the students to use the techniques used in class…

The normal freezing point of water is zero degrees celsius which means any temperature above this will make ice melt. Also water is H2O or hydrogen and oxygen so, freezing and melting water takes about ten minutes. In my experiment, the object that is going to be testing will be, the rate of ice melting with…

The Dominican Republic is a very beautiful country with delicious food, amazing music, various beaches and waterfalls. It’s considered one of the most beautiful islands in the world with its white sand beaches, vast mountains, amazing waterfalls and impressive lakes. It’s located in both the Northern and Western Hemispheres. Dominican Republic shares the island with Haiti and the entire island is known as the Hispaniola. The Hispaniola earned its name when Christopher Columbus went on his first…

DISTILLATION The purpose of experiment 1, fractional distillation and gas chromatography, was to separate an unknown organic mixture into two liquids. The primary process of separation was fractional distillation, which utilizes the physical properties of the two unknown volatile liquids. Once the unknown mixture was successfully fractioned, gas chromatography was used to help determine the identity of the two unknown liquids. Fractional distillation and simple distillation both take advantage…

article, McKibben develops the claim that climate change is the result of many companies greed problems, and argues that we must sever ties with those who profit from climate change now. McKibben builds his argument around three numbers, 2 (degrees celsius), 565 (gigatons of CO2), 2795 (gigatons of…

crops produces biogas. The whole process works like a big concrete stomach would: Organic materials like manure, food scraps, crop residue, or wastewater sludge (known as feedstock) are fed into the digester, where it’s heated to 38-40 degrees Celsius (temperature of a cow’s stomach) and stirred for 30-60 days, slowly producing a combination of methane, carbon dioxide and other gases (known as biogas). There are two key processes: mesophilic and thermophilic digestion which is dependent on…

Ever since humans have started polluting causing the ozone layer to become thinner, allowing more UV rays from the sun to come. This correlates directly into stronger UV rays entering earth's atmosphere and harming living things all over. Some creatures that are the most susceptible to these UV rays are amphibians. There are three kinds of UV rays, UV-A, UV-B, UV-C. The kind that hurts the amphibians the most is UV-B because Most molecules do not absorb the higher UV-A wavelengths and most of…

In the South Pacific Ocean, about 1,300 miles north of New Zealand, there is a country that is made of 300 islands and 540 islets. These islands combined form the republic of Fiji. Out of all 300 islands, only about 150 are inhabited by humans. The largest island is Viti Levu, also known as Great Fiji, and the capital is Suva. Fiji is a democratic country, with the government system set up very similar to the United States. Sports are also popular in Fiji, such as rugby and soccer. My goal…
