Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules

profiles are encrypted sets of numbers that reflect a person’s DNA makeup‚ which can also be used as the person’s identifier. DNA profiling should not be confused with full genome sequencing. It is used in‚ for example‚ parental testing and rape investigation. Although 99.9% of human DNA sequences are the same in every person‚ enough of the DNA is different to distinguish one individual from another. DNA profiling uses repetitive ("repeat") sequences that are highly variable called variable number

Registry analysis is an important step for forensic investigators to collect evidence that supports their case. While running the malicious program‚ they will leave some traces as other programs which act as an important role to these investigators. The Windows Registry holds a great deal of information about the system such as the settings and configuration of the system. Firstly‚ the name of the computer is available in the following Registry sub key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName

There are many factors that affect the rate of reaction of bromelain on jello‚ these include pH‚ temperature and substrate concentration. In this demonstration‚ we were able to assess the effect of substrate concentration of pineapple (Containing bromelain) on jello. Our results showed that the relationship between rate of reaction and the change in mass of the jello is proportional. This can be seen that the higher the change in mass of jello‚ it would demonstrate a higher reaction rate‚ as the

Research Question How does the mass of the sandbag affect the amount of time the parachute takes to hit the ground? Hypothesis I predict that if the sandbag is lighter‚ the more time it will take for the parachute to reach the ground. The sail provides a drag pulling upwards to decrease the gravitational force that makes the sandbag fall‚ which is the mass times gravity. Thus‚ the lighter the sandbag‚ the less force there is pulling it downwards and‚ as a result‚ it travels slower and takes

Crime Scene Investigations by First Responders Crime scenes contain the forensic evidence required to apprehend criminals. The proper collection and processing of physical evidence is of primary importance to most police investigations. Evidence can not only establish the fact of the offense and identify the perpetrator; it may even lead to a conviction. In collecting this evidence we must be conscious of the public’s Fourth Amendment rights and not violate them in this collection of evidence. Unfortunately
