The nine properties of life are as follows‚ Order‚ Metabolism‚ Motility‚ Responsiveness‚ Reproduction‚ Development‚ Heredity‚ Evolution and Adaptations. To understand what each of these properties are and their role in life‚ each characteristic will be discussed. First‚ Order is defined as a precise arrangement of units and activities structured together. Second‚ Metabolism is the chemical reaction that is a acquired usage to repair‚ grow and other survival processes. Third is Motility‚ the usage

applied magnetic field (spin glassbehavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. They includecopper‚ aluminium‚ gases‚ and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state. The magnetic state (or phase) of a material depends on temperature (and other variables such as pressure and the applied magnetic field) so that a material may exhibit more than one form of magnetism depending on

Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

Report Submitted: February 17‚ 2013 Title: Physical and Chemical Properties Purpose: To investigate and learn the physical and chemical properties of pure chemical substances. Procedure: I used various different tools to investigate the different physical and chemical properties‚ such as blue and red litmus papers‚ beakers‚ and wells. Data Tables: Substance Name Color Odor Heat Effect Cold H2O Hot H2O Litmus Test Dilute HCl Dilute NaOH Mg Silver None None None Not soluble‚ small bubbles Red

List of the First 20 Elements and their Physical Properties Atomic Radii (pm) of the First 20 Elements: - Atomic radii decreases when moving down a period‚ as the number of protons increases‚ which thence increases the effective nuclear charge. - Atomic radii increases when moving down a group‚ as the number of shells increases‚ which thence increases shielding. - The downward-sloping pattern on the above graph shows the decrease in atomic radii down a period‚ and the sudden jumps

crucial subject for information security. The password based authentication is weak solution and no longer adequate. User select static password which is easy to guess and remember‚ relevant information or common for all authentication process. This simplicity makes weak authentication scheme; as so far‚ static passwords are known as easiest target for attackers. Further‚ Security Token based runtime interaction could extend the strength of authentication control. Security tokens can be used for strong

Human security is an emerging paradigm for understanding global vulnerabilities whose proponents challenge the traditional notion of national security by arguing that the proper referent for security should be the individual rather than the state. Human security holds that a people-centered view of security is necessary for national‚ regional and global stability. The concept emerged from a post-Cold War‚ multi-disciplinary understanding of security involving a number of research fields‚ including

Security Brutality Before the year 2000 airports were smooth transportation services. People could enter an airport and basically walk right on to their planes without being hassled by airport security. Air travel safety precautions changed dramatically after the September 11‚ 2001‚ terrorist attacks that targeted passenger planes in the United States. After many years of upping security in airports‚ the Transportation Security Administration knew that metal detectors weren’t enough to pick up

Antimicrobial Properties of Plants A plant with antimicrobial properties means that it destroys or inhibits the growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the
