MOLECULAR BIOLOGIST Education/Training Required: All molecular biologists must at least earn a bachelor’s degree in a related science field. Required courses usually include cell biology‚ evolutionary biology‚ genetics‚ ecology‚ general chemistry‚ biochemistry‚ organic chemistry‚ physics‚ molecular biology‚ multivariable calculus‚ and linear algebra. Most jobs for molecular biologists require a doctoral degree. During college‚ students may want to participate in science-related activities

in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must cool and then

Section 10-1 The Kinetic-Molecular Theory of Matter Prerequisites The kinetic-molecular theory is based on the idea that particles of matter are always in motion. The theory can be used to explain the properties of solids‚ liquids‚ and gases in terms of the energy of particles and the forces that act between them. ideal gas: an imaginary gas that perfectly fits all the assumption of the kinetic-molecular theory. Kinetic-Molecular Theory of Gases (based on the following 5 assumptions) Most

7.6 Summary 1. 7.6 Molecular Orbital Theory a. Intro i. Molecular orbital theory states that the atomic orbitals involved in bonding actually combine to form new orbitals that are the property of the entire molecule‚ rather than of the individual atoms forming the bonds. 1. The new orbitals are called molecular orbitals. ii. Electrons shared by atoms in a molecule reside in the molecular orbitals. iii. Molecular orbitals are like atomic orbitals

Sodium borohydride Reduction of Benzil Introduction: The Purpose of this experiment is for the students to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols‚ and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product‚ the metal hydride nucleophile of the reducing agents such as LiH‚ LiAlH4

The World’s Smallest Cottage According to my mother‚ everyone has to go through trials at some point in their life. For me‚ I suppose one of my trials was being the middle child and only girl of five children. I don’t know why I was stuck with four brothers‚ but sometimes life just decides to whack you in the face doesn’t it? At the moment‚ I was squished in the car between my older brothers Davis(the smartest)‚ Finn(an annoying nuisance)‚ and my younger brothers‚ Michael whom we called Mike(a real
