Degrees Celsius Atomic Mass
318 wordsAn American Chemist named Glenn T. Seaborg discovered plutonium in 1941 at Berkeley University in California. The discovery of Plutonium was not announced until 1946 because America was at war with Japan and Germany. Plutonium was named after the planet Pluto, after the planet Neptune in the solar system and Neptune gave its name to Neptunium. Plutonium is a silvery metal that turns yellow when exposed to air. It is warm to the touch due to the releasing radioactive energy from it. The atomic nu...

Sulfuric Acid Sodium Hydroxide
1,751 wordsAcid Rain Written by: Ali Right Introduction Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5. 6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of...

Cystic Fibrosis Autosomal Recessive
1,073 wordsCystic fibrosis is a debilitating disease facing many people today. At the present time there is no cure available. According to the cystic fibrosis foundation of America, cystic fibrosis can be traced back as early as 1595. The first documented case was not reported until 1936. One group of people that seem to be affected the most by cystic fibrosis is Caucasians. Recent statistics indicate that 1 in 3, 200 live caucasian births are afflicted with cystic fibrosis. For reasons that are currently...

Second, 'psychotomimetic effects similar to those induced by PCP can be induced by ketamine, a related arylcyclohexamine derivative' (Sevvenson, 1995). This is a particulary strong point of evidence, especially when coupled with the following point: A dosage of ketamine ten times that of PCP is required in order to induce the same effect (Halberstad, 1995).

This classification is not definitive in including all proteins, since there may well be other examples that span the membrane with different numbers of anchor chains. The structure of proteins varies greatly. The first factor affecting structure is the proteins function, but equally important is the proteins location, a...

Life On Earth B And C
1,459 wordsCarbon dioxide is a colorless, odorless, non-toxic, and slightly acid-tasting gas. Sometimes referred to as a carbonic acid gas, the molecule consists of one atom of carbon joined to two atoms of oxygen. It occurs naturally in the atmospheres of many planets, including that of earth. Carbon dioxide is uniformly distributed over the earths surface at a concentration of about 0. 033 %, or 330 parts per million. It was called fixed air by the Scottish chemist and physician Joseph Black in the 1750 ...

Electron To Form Covalent Bond Bonds
446 wordsChemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, which concludes in an ionic ...

Active Transport Membrane Potential
2,258 wordsEffects Of Solutions On Ion Transport Across Membranes Abstract Concentration gradients exist between two different salt molarity solutions on opposite sides of a membrane. Movement of ions across these sides can be achieved by either active or passive diffusion. In our first three experiments we used these concentration gradients to determine the characteristics of selective permeability of an artificial membrane to potassium chloride (KCl), the potential difference across the skin of a frog, R...
