BHS002-1 Microbiology Practical Manipulation of bacteria – Part 1 Week 45 Since the early days of microbiology in the 19th century‚ culture on agar plates has been a central technique for the study of bacteria. This practical is designed to introduce students to the basic techniques required to manipulate bacteria. Students will gain experience with the streak plate procedure‚ used to isolate pure colonies of bacteria‚ and viable plate count methods. The latter involves serial dilution and spread

DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel. Note: This method has been adapted from one developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory. More details are available from the DNA Learning Center’s

Business‚ A Practical Introduction Chapter 3 Pop Quiz answers 1. Scarcity increases the demand for a product‚ and increases the price that consumers are willing to pay for it. Scarcity of an item allows a seller to raise prices‚ while a surplus of an item means prices will decrease. 2. Macroeconomists would be concerned with issues such as job growth and unemployment‚ growth in industrial production‚ and the consumer price index. 3. Under a socialist economic system‚ businesses

9.2 T1P: Pendulum Practical Report Aim: To determine the value of gravitation acceleration using the motion of a pendulum. Identify the causes in variation of this value. Equipment: * Slotted Weight * Retort Stand * Sticky Tape * Clamp * String * 1 metre ruler * Timer Method: * 1. Gather required equipment. * 2. Place retort stand onto table and tightly secure the clamp * 3. Tie the slotted weight onto one end of the string‚ and wrap the other end

Week Three Practical Problem Questions A. Determine T(n) for n = 6‚ 7‚ & 8. T(6)=(2*6*10*14)/(6-1)!=14 T(7)= (2*6*10*14*18)/(7-1)!=42 T(8)= (2*6*10*14*18*22)/(8-1)!=132 B. Do you detect a pattern to these numbers? This pattern may arise out of the numbers or the manner in which you generated triangulations. (A closed-form function for T(n) is relatively straightforward‚ but is fairly nontrivial to construct; you will not have to explore that here.) The pattern for these numbers

Autopsies are vital to homicide investigations as they are the examination of a corpse by dissection and evaluation to determine the cause‚ mechanism‚ and manner of death. Geberth’s Practical Homicide Investigation does an excellent job in explaining these concepts. Cause of death is anything that is resulted in an individual to have died‚ which can be caused by an injury‚ illness‚ or anything that could cause harm to the body (Geberth‚ 2015‚ pg 815). Examples of causes of death are people dying
