An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller‚ which regulates the amount of power transmitted throughout the vehicle‚ based on the driver’s use of an accelerator pedal. The electric motors give electric cars instant torque‚ creating a strong and smooth acceleration pattern. Electric cars are about three times more efficient than cars with an internal combustion engine. A pure-battery electric car uses energy stored

What genetic mutations produce the greatest risk of skin cancer? Cancer begins when one or more genes in a cell mutate. This either creates an abnormal protein or no protein at all‚ which causes mutated cells to multiply uncontrollably. The Most common gene to carry skin cancer would be the MC1R (melanocortin-1 receptor). Increasing evidence is showing that the greater number of variations in this gene‚ the greater the risk for melanoma. It also carries a more moderate risk that the CDKN2A mutation

Lab Title: Microscopy Objective: To learn how to use and care for a microscope and to know the parts of a compound microscope and to efficiently use the microscope to focus on specimen. Introduction A microscope is an optical instrument used for viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument

The uppermost strand in this structure is called the coding strand. The second strand that lies below the coding strand is called the template strand. In order for a RNA polymerase to go from the upper strand to the second strand it must go through the process called transcription. First‚ the RNA polymerase must attach on to one of the genes on the coding strand on DNA. Once the RNA polymerase attaches‚ it must then begin the process called initiation. This means that the RNA polymerase opens up

The Lincoln Electric Case International Strategic Management By: Group 4A Introduction John C. Lincoln founded the Lincoln Electric Company in the year 1895. The first products that the company produced and sold were electric motors that he had designed himself. A Few years later‚ in 1907 his brother James‚ a recently graduate from the Ohio State University‚ joined as a senior manager; He was also the one who would introduce different and very innovative human resource policies

General Electric Under Jack Welch John Francis Welch‚ Jr.‚ also known as “Jack”‚ became the CEO of General Electric in 1981 and maintained this title for the next 20 years until his retirement in 2001. He was widely known as a “national business hero” because he had a different approach on management that provided increasing results. For this very reason‚ many also despised his tactics. He was very aggressive in cutting out the weak‚ because he believed that it was holding back the company. One

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from
