Blood is the best known as significant evidence in modern criminal justice. Blood evidence is important to an investigator because it can link a victim to a suspect (Locards Exchange Principle). Bloodstain patterns can reveal a great deal about the position and movement during the crime. Blood has managed to destroy self-defense arguments from the suspects. The fluid portion of the blood consists of plasma and serum while the non-fluid portion consists of red blood cells. Blood is composed of water

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Blood Clots What are blood clots? Blood is a liquid that flows within blood vessels. It is constantly in motion as the heart pumps blood through arteries to the different organs and cells of the body. The blood is returned back to the heart by the veins. Veins are squeezed when muscles in the body contract and push the blood back to the heart. Blood clotting is an important mechanism to help the body repair injured blood vessels. Blood consists of: · red blood cells containing hemoglobin that

The biological level of analysis consists of the following principles: 1. Behaviour is innate because it is genetically based 2. Animal research can provide insight into human behaviour 3. There are biological correlates of behaviour The Biological level of analysis is vital in helping us to understand how soldiers may be affected differently in similar situations. This level of analysis focuses heavily on the brain itself and its functions. This level of analysis helps us to understand

I.Cerebrospinal Fluid Cerebrospinal fluid is a clear‚ colorless liquid produced within spaces called ventricles in the brain. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and the spinal chord. It bathes the exposed surfaces of the central nervous system‚ and completely surrounds the brain and spinal cord. In addition‚ a space inside the spinal chord called the central canal also contains cerebrospinal fluid. CFS acts as a cushion for the neuraxis

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap
