In fish, neurological functions, intermediary metabolism, antioxidant activity, epithelial transport, and other physiological and biochemical systems are damaged by cadmium .All of these harmful bioinorganic effects are largely due to occupational or environmental exposure to in-excess levels of cadmium through inhalation or ingestion of fine air particulates and consumption of cadmium-exposed plants, animals, or water. Cadmium is harmfully introduced into the environment as carcinogens through processes of fossil fuel combustion and waste incineration, and as in-excess terrestrial deposition through metal mining processes, phosphate fertilizer and pesticides containing cadmium usage in agriculture, and improper chemical waste (such as old batteries) and sewage sludge disposal. Even seemingly small introductions of cadmium to the environment can cause contamination at a large scale, particularly when a contamination process is repetitive . Pollution from surface runoffs and subsurface flow can leach into river systems and ground water, affecting surrounding ecology, crops and livestock. Drinking any affected

Product Choice Purpose and Characteristics of Bird Feeder Product Bird feeders are devices placed outdoors to supply food to birds. Most bird feeders supply seeds such as Millet, Sunflower, and Rapeseed. There are different kinds of bird feeders on the market today such as Tray feeder, Tube feeder and Hopper feeder, and different choices of food to put in them. Bird feeders often are useful for bird watching which has been a tradition in many places; it provides people with wonderful opportunities for close viewing of birds.
Adrian Del Bosque Mr. Straub Physics, Honors Essay 7 December 2012 Physics in Golf INTRODUCTION The primary purpose of the golf swing is to do work to generate club head kinetic energy, which is eventually transferred to the golf ball at impact. Golfers wind up during the backswing to create and transfer potential energy to the shaft of the club at a nearly perfect timing so the momentum of the club is at its peak during impact. This energy is produced thanks to a series of rotations and angles that are created as the golfer winds up. In this paper, power in a golf swing will be analyzed as well as how it is produced and maximized. The golf club is a major factor in power creation, especially the shaft’s flexibility.
Originally invented in 1965 to mimic the effect of cataracts on chickens, the contact lens for use on chickens was a result of collaboration between Robert D. Garrison, an inventor, and Ronald Olson, an owner of a large chicken farm in Oregon. After product conceptualization, development, and testing, the two men, accompanied by an investor, saw the project as feasible and by late 1966 they had formed a corporation; Optical Distortion, Inc. (ODI). The company was formed in response to the relatively ineffective practice of debeaking. The process of debeaking is the current and most popular process of trimming the chicken’s beaks in order to prevent cannibalism, which is caused by the close proximity of the birds to each other within their cages. By debeaking the chickens, their method of attack is eliminated and therefore morality rates are decreased and productivity is improved.
Ricinus communis (ricin) is one of the most deadly toxins that has been discovered. It is a protein toxin extracted from the castor bean plant and a single molecule can kill an entire cell. The mechanism of action is by destroying the ribosome within a cell, which prevents protein synthesis. The toxin works as a slow poison, eventually causing a total body failure, as necessary proteins are not replaced. This common toxin can be found in gardens and wild areas around the world and is wildly grown for the oil it produces.

Copper (II) sulfate is toxic to fish, and must be used wisely when eradicating pesky snails and fish parasites. To protect our water pipes, we use Copper (II) sulfate to keep evasive water plant roots at bay. This special Compound is also a helping hand in organic synthesis, reacting with potassium permanganate to make an oxidant for primary alcohols. At one point in the medical field Copper (II) sulfate was used as an emetic, which made a patient throw up immediately after consumption, but is now regarded too toxic for this use. The most interesting use most would say, is the way Roger Hiorns used 75,000 liters of Cu(II)SO4 to fill an apartment, and left it to solidify for many weeks.
She elaborates on the issue of spraying chemicals and if it is increasing or decreasing the progress in the world. Carson’s article states that we are hurting ourselves more than we benefit ourselves from the spraying of harmful chemicals, and that we endanger our environment with these chemicals. In order to persuade the progressive intellectuals of this argument, Carson provides data to show the actual harm the pollution from the chemicals is causing, and provokes fear in her audience. In order to make her argument appear reasonable, Rachel Carson uses scientific observation to demonstrate how chemicals are the cause of killing pests. Carson provides rational examples to show the harm that pollution is causing to the earth and pests.
The authors of the study had this to say about the effectiveness of the toxin on insects: “L]ow toxicity with an LC50 of 18.4 μM was recorded in artificial diet incorporation assay in which the toxin was consumed by the testing insect through feeding. We suggested that this might be a result of toxin degradation by digestion.” This suggests that infect, when ingested by the insects, the toxin may not actually be effective. Basically, the breaking down of the food by the natural processes of digestion may actually cause the poison to be totally useless as opposed to if it were directly applied like it is on a scorpion’s tail. This means that if the cabbages were to ever be infused with the scorpion poison, it is likely that they will still be sprayed with pesticide on top of this genetic modification, which could still lead to the same troubles caused by pesticides as well as the risk of humans becoming sick due to the scorpion toxin. Tests on normal, healthy cells or humans have yet to be carried out and it is unlikely that this
