Dynamic Chemistry Matter – Any substance that has volume & mass. E.g. EVERY THING Atom – The smallest non living thing that can exist. Atomic Structure – Particle | Symbol | Location | Charge | Mass | Proton | P | Nucleus | +1 | 1Heavy | Neutron | N | Nucleus | 0 | 1Heavy | Electron | E | Electron Shell or Orbit | -1 | 12000Light | History of the Atom – The model of the atom has changed with time. Dalton – solid shape (no subatomic particles) (indivisible particle) Rutherford

Increased sweat rate‚ body and skin blood flow shifts‚ cardiac output‚ respiratory rate‚ and a sensation of heat intensity are the responses triggered to regulate the core temperature. Bi-directional routes for heat exchange are: convection (Cv)‚ conduction (Cd)‚ and radiation (R) and two uni-directional routes are: metabolic heat (M) which increases thermal load; evaporation (E) which decreases the thermal load. The net heat storage (S) formula is: S = M +/- Cv +/- Cd +/- R – E When the net heat storage

1 Chapter 1 INTRODUCTION Alcohol drinking has been practiced in the majority of human society since early times. Alcohol (ethyl alcohol) is a drug which acts principally as a depressant on central nervous system. Its effects on behavior are well known and regular use gives rise to an increased tolerance‚ so that the drinker needs to take gradually increasing amounts to obtain the same effect. Chronic excessive alcohol consumption leads to life threatening hazards (Best‚ 1999). Alcohol related diseases

Man-of-War The Portuguese man-of-war if a member of the Kingdom Animalia‚ phylum Cnidaria(1)‚ class Hydrozoa‚ order Siphonophra‚ the genus Physalia‚ and the species Physalia(2). The man-of-war is not an actual jellyfish‚ but a Siphonophor. Also the man-of-war is not a single organism. It is made up of many different organisms that work together. These organisms are called polyps. The Portuguese man-of-war is usually found in the Northern Atlantic gulf stream. It can also be found in the tropical

Neuro notes for test 2! Cell membranes are composed of a lipid bilayer. It has different receptors that allow different ions to pass‚ depending on the conditions in the cell. Leak channels- always open allow ions to flow back and fourth across the cell membrane Na cl ‚K and Ca ions and they just flow back and fourth without any gate keeper or obstruction‚ When the neuron is at rest its cytoplasm is Negatively charged. That means that it is not going under depolarization‚ we use the term resting

concentric contractions‚ the force generated by the muscle is always less than the muscle’s maximum. As the load the muscle is required to lift decreases‚ contraction velocity increases. This occurs until the muscle finally reaches its maximum contraction velocity. By performing a series of constant velocity shortening contractions‚ a force-velocity relationship can be

on the RDI amounts‚ however‚ if I keep under 2300mg I should be okay. This can be easily achieved by eating less processed food and preparing more meals at home where I can control the salt content. Our bodies need sodium for fluid balance and nerve conduction‚ but excess sodium can have negative effects. High sodium intake can cause numerous effects‚ high blood pressure‚ heart problems and kidney problems. High blood pressure causes more stress on the heart and vessels and should be kept below 120/80
