probability‚ vulnerability and risk. Hazard is a circumstance that has potential to lead to an emergency or disaster. Probability is the likelihood that a hazard will occur. Vulnerability is the susceptibility of life‚ property or the environment. Finally‚ risk is the probability of suffering damages. A hazard analysis determines what can occur‚ how often‚ how bad‚ how likely it is to affect the country

Nucleation As in solidification‚ nucleation occurs most easily on surfaces already present in the structure‚ thereby minimizing the surface energy term. Thus‚ the precipitates heterogeneously nucleate most easily at grain boundaries and other defects. Growth of the precipitates normally occurs by long-range diffusion and redistribution of atoms. Diffusing atoms must be detached from their original locations (perhaps at lattice points in a solid solution)‚ move through the surrounding material

attaches to the myosin head‚ it gets hydrolyzed to ADP and Pi. Calcium ions bind to the troponin molecules and help expose the binding sites of actin filaments to allow for the attachment of the myosin heads. After the sliding of the myofilaments occurs‚ a new ATP is required to unbind the cross bridge between the actin and myosin filaments. To test the response of muscle fiber to the addition of ATP and/or salts (KCl and MgCl2)‚ we conducted an experiment in which we added salts only‚ ATP only‚

FORMATION OF BLOOD CLOTS Definition • A blood clot is a mass of blood cells and blood components that form to stop the bleeding that occurs when a blood vessel is injured. When a blood vessel is broken‚ platelets in the blood become sticky and clump together at the site of the injury. They begin to form a mass to stop the flow of blood. Description • Clotting is the body’s normal response to a bleeding injury. It is a necessary function to prevent a person from losing too much blood

a young person performing contact‚ high impact and repetitive sports. There can be both positive and negative outcomes to a young performer. Positive effects can be the strengthening of the body. Negative effects can be that serious injuries can occur to the undeveloped young performer’s body and not be able to do that sport after. The skeletal system and the muscular system are both systems in the body that can benefit more from regular physical activity. Due to regular physical activity‚ the

mitosis and meiosis. Mitosis is usually used for the growth and replacement of somotaic cells‚ while meiosis produces the gametes or spores used in an organism’s reproduction. Hypothesis: Mitosis occurs in whitefish blastula and onion root tip‚ and it is easily observable. Meiosis and crossing over occurs in the production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula‚ onion root tips‚ ovary‚ and testis‚ a microscope‚ and chromosome kit. The prepared
