THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

Bioassay of Radish Seeds Bioassay is a type of scientific experiment used in the development of new drugs and monitoring pollutants. It estimates the potency of a substance‚ by testing its effect on living matter. In other words‚ it determines how much of the substance is needed to poison an individual‚ without testing it on any humans or animals. From here the TC50 of the substance can be adjusted for dealing with humans and animals over plants. In this lab we attempted to find the potency of

The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

If the movement of people‚ food‚ and manufactured goods can have such a negative impact on public health‚ should steps be taken to reduce these flows? On the surface‚ it would seem that the conservative notion of imposing strict limitations to protect public health would be best. Yet‚ all that does is promote isolation. Historically‚ the countries that have fared the best‚ are those that have met disease head on. (Globalization 101‚ n.d.) There are many casualties from such events

posting regarding the pros and cons of mandatory GMO labeling this week. Furthermore‚ similar to you‚ I thought it was highly important to provide a clear definition of a GM or GMO product at the beginning of my primary task. In addition‚ you cited an exceedingly interesting fact‚ one I had not found during my research‚ that in almost all study cases the GM crops produced 6 to 11 percent less yields for studied soybean crops (Exposed: the great GM crops myth‚ 2008). The fact was so compelling‚ I must

During the Toxicity of Morton Salt on Radish Seeds experiment‚ we measured the levels of iodized Morton Salt to the growth rate of radish seeds. Each six packets had ten radish seeds with different level of iodized salt solution. The packet with no iodized salt solution grew the longest in a period of days‚ compared to the other packets that had iodized salt. Solutions 100% and 10% had no growth progress within the past five days. As for solutions 1%‚ .1%‚ and .01% grew‚ yet not as much nor fast

A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of

Major food companies across America are launching a last ditch effort in congress to have mandatory GMO labelling scrapped before the year ends. According to The Associated Press (via Yahoo)‚ the food industry is pushing to make the labelling a voluntary process and is trying to get the legislation passed in a spending bill that lawmakers from both the Republican and Democratic parties are trying to finalize before the holidays. If this proposal were to become law‚ companies would not be required
