Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

Genes are molecular units of heredity which encode for different types of traits. Each organism has traits that are defined phenotypically and can be studied though the field of genetics. Genetics is the study of genes‚ heredity‚ and how they cause variation in different living organisms. Scientists study genetic pattern in different organisms to determine the different trends in a certain population. In every organism‚ we obtain one allele from each parent. Alleles are types of genes that can be

Introduction and background There are a myriad of areas in the field of forensic science. One specific area is that of forensic biology; the application of biology to law enforcement. This discipline has been used to solve crimes by matching crime scene evidence to suspects‚ identifying victims and determining paternity to name a few. DNA based techniques are a sub-discipline of forensic biology and are a crucial component in this field of work. DNA analysis began in the mid 1980’s and revolutionised

measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules from an area of higher concentration to areas of lower concentration (Martini & Nath‚ 89). Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane

MRI Background info Magnetic resonance imaging (MRI) otherwise known as Magnetic resonance tomography (1) is a scan that uses a magnetic field‚ radio wave‚ and computer‚ to produce an image of an individual internal structure (Anatomy) (2). The body contains more than 50% of water. MRI uses super strong Magnetic field to align hydrogen nuclei or protons found in water (H2O) all over the body (1‚3‚ &‚ 4). When a person is placed into the scanning machine hydrogen nuclei or protons align
