How do scientists explain and support the argument for biological evolution? From the recent trip to the Minnesota Zoo, labs performed in class and multiple readings these things have shown students the dynamics of evolution. Scientists, like Charles Darwin, who have focused studies on certain organisms like the Galapagos Island finches have played a large role in our knowledge today about biological evolution, natural selection and descent with modification. Over many generations and an…

Richard Dawkins is a well-known biologist and a writer who takes after Charles Darwin. Charles Darwin was the man who originally discovered the possibility of natural selection. Scott LaFee is a science writer who believes that Dawkin’s work proves that he is very similar to Charles Darwin. “Richard Dawkins, the 68-year-old English biologist and best-selling author, whose rousing defense and explanations of evolution have earned him international admiration, the enduring enmity of creationists…

In 1859 Charles Darwin published his book “The Origin of Species”. This book explained his theories of how animals and humans were formed. The beginning of the earth has been a mystery frustrating the minds of scientist for many years. Darwin’s Theory of Evolution is a change in the genetic material of a population of organisms from one generation to the next. Though changes produced in one generation are normally small, differences with each generation overtime can become substantial changes in…

Although there are four viewpoints portrayed in this book, some tend to agree but on opposite ends of the topic. I will start with the ones who, contrary to the last chapter when they were the ones on opposite sides, completely disagree. Professor David Davies is an evolutionary biologist, so naturally on this position, he is for evolution. Davies starts his argument with mentioning that there are many different organisms on the planet and that they all share a common ancestor. Davies also…

I will start off by saying that I don’t think any one person is the greatest in history. There have been many who have left their mark on the world. A person who I may find to be brilliant may mean nothing to another from a different culture or religion. With that said, I would say, Charles Darwin is one of the most important people in history. Charles Darwin was born in England February 12th, 1809. At the age of 18 he embarked on a five year voyage aboard the HMS Beagle. The ship was taking a…

different types of chemical reactions such as double displacement, single displacement, decomposition, and synthesis reactions were observed. During the lab there 4 stations A, B, C, and D each letter has two different options to choose from. The students job is to choose the option that will create reactants that reach the standards for the reaction to be considered safe. The purpose of this lab is to give students a better understanding of chemical reactions, how to identify if a chemical…

the reaction of benzil with ethanol and potassium benzilate. In order to produce benzil, benzoin was reacted with nitric acid. A crude product of benzil was produced from the reaction of benzoin and nitric acid. Through the process of multi-step synthesis, benzil was produced through the oxidation of an alpha-hydroxyketone to an alpha-diketone using nitric acid. Prior to the reaction of nitric acid and benzoin, nitric acid was protonated to form an oxonium ion. The hydroxyl group on benzoin acts…

Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

“Explain how carbon’s electron configuration determines the kinds and numbers of bonds that carbon will form.” Carbon atoms are the most versatile building blocks of molecules. This is because its atomic number is 6 and has 4 valence electrons. The completion of the outer valence shells is done by sharing of electrons four covalent bonds. This results in a stable single covalent (flexible) bond with 4 other atoms. They can have either a double or a triple (inflexible) bonds with the other atoms…

This essay will be talking about Reactions and how it affects substances.A reaction is a chemical process in which two or more substances act on each other and are changed into different substances, or one substance changes into other substances.There are eight reactions we will be talking about and they are Decomposition,Combustion,Acid and Base,Synthesis,Single-replacement,Double-replacement,Precipitation,and Redox.In the world today there are many reactions out their but we will only be…
