Neonicotinoids, commonly referred to as neonics, are a rather new variety of pesticides, having been manufactured and marketed for the last twenty or so years. Neonics are systemic pesticides(Hopwood, Vaughan and Shepherd 3). Contrary to contact pesticides that remain on the surface of the plant, systemics are absorbed by the plant and moved to all the tissues of the plant. Neonics can be sprayed at the root of a plant or sprayed onto its foliage. Once applied, neonics remain active for many weeks, protecting the plant throughout the season. Several neonics are sold for application to lawns, pot plants and crops raised in a greenhouse.
A miticide, also known as acaricide, is any chemical substance used to control ticks and mites that are not affected by regular pesticides. Miticides are specifically designed to destroy those species of ticks and mites that damage food crops and ornamental plants(Burley 5). Some of the most commonly used miticides include tetradifon, azobenzene and dicofol. Most miticides are designed to kill the eggs and larvae of pests, but some also kill adult pests. Some miticides are known to be poisonous to honeybees and other useful insects. Despite knowledge of this adverse effect of miticides on honeybees, these substances continue to be manufactured and applied to crops widely in the country.
An antibiotic is defined as a molecule or an agent that either kills or interferes with the growth of a living thing that is too tiny for the naked eye, also called a microorganism(Hawthorne and Dively 26). These microorganisms include both fungi and bacteria. Selman Waksman first coined the term in 1942 in their journal articles. They used the term to describe any substance that a microorganism produces and inhibits the growth of other microorganisms. "Bactericidal" antibiotics kill bacteria ...Download file to see next pagesRead More

...?Excretion The body is an amazing and complex system of reactions all working towards maintaining homeostasis. Excretion is one such function of the body which works to remove excess wastes and toxins. Some of the major organs involved in various excretions are the lungs which help to remove built up carbon dioxide and moisture from the body. The skin also aids in removing excess water, salts and even urea through perspiration. One main organ which facilitates excretion is the kidneys. These are part of the excretory system which works to clean the blood and filter out cellular wastes, toxins, nutrients and excess minerals. The normal breakdown of tissue and the left over products from food and liquid intake deliver wastes... The body is an...

...?Methylation is the addition of a methyl group to a substrate or the substitution of an atom or a group of atoms by a methyl group. A methyl group, CH3, is an alkyl group derived from methane, CH4, by lost of one hydrogen. The methylation process converts inorganic (metal) mercury, Hg, to methyl mercury, CH3Hg+. As a positively charged ion, methyl mercury combines with anions, such as chloride (Cl-), nitrate (NO3-), hydroxide (OH-), and sulphur containing anions, such as thio groups (SH). Indeed, the thio group on the amino acid cysteine and hence in proteins containing cysteine has high affinity for methyl mercury forming a strong covalent bond. Methyl mercury can coordinate (bond) to more than one cysteine amino acid. Unlike... is the...

...?Individuals who smoke and are exposed to asbestos have a significantly higher rate of asbestosis than individuals who do not smoke and are exposed to asbestos. Why? Asbestos is any of the several minerals that separate readily into long, flexible fibers with chrysotile being the best known and most commonly used. It is a hydrous magnesium silicate with chemical compound with the formula Mg3Si2O5(OH)4. It is long known that prolonged exposure through inhalation of some forms of the tiny fibers can result in a lung condition known as asbestosis which is a rapidly fatal form of lung cancer. Furthermore, epidemiologic studies have established that cigarette smoking seriously aggravates the symptoms of asbestosis and increases... who smoke and...

...? Running Head: Toxicology Toxicology Inserts His/her The ALAD gene provides instructions for making an enzyme known asdelta-aminolevulinate dehydratase, which is important in the production of “heme”. Heme is a molecule that is necessary for all of the body's organs, as it is a crucial part of quite a few iron-containing proteins, which also includes hemoglobin (McGuire & Beerman, 2009). This is the protein that carries oxygen in the blood. What sometimes happens is that genetic mutation causes the amino acids in this enzyme to change, and this change lessens the movement of this enzyme in the body, due to which the human body experiences high toxic levels. The ALAD gene may pose the danger of developing...

...Toxicology Answer Organic phosphate or OP compounds are a of chemicals used in both domestic and industrial sectors. They are commonly used in agriculture, chemical warfare and public health eradication programs. Some of the commonly used OP compounds are insecticides like parathion, malathion, dichlorvos, ethion, chlorpyrivos, diazinon and fenthion; antihelminthic agents like trichlorfon, herbicides like tricresyl phosphate and nerve gases like sarin, soman and tabun (Katz and Brooks, 2010). Most of these compounds are either amides, esters or thiol derivatives of phosphonic acid (Kamanyire and Karalliedde, 2004). These compounds are notorious for their health hazards. Most of the health effects are due to inhibition... Answer Organic ...

Movement of solute particles across a semi-permeable membrane down a concentration gradient without energy expense is passive diffusion. All biochemical systems move towards a state of homeostasis or equilibrium. The biological membranes are semi permeable to majority of small sized molecules that frequently need to cross them in order to maintain...

...Toxicology Introduction Toxi refers to the final effects of an event where a living organism got exposureto chemical, physical, or biological agents (Kacew, & Lee, 2013). Processes that occur prior to toxicity commence at absorption, ending at excretion. The effects of such an exposure can be either mild, risk to organs, or even life threatening. Toxicology is the study of toxicity and it covers all biological organizations. It embraces concepts from other scientific subjects to measure the degree of exposure as well as the modes of prevention. There are number of toxicology disciplines, which relate well to occupational health and safety as they protect the staff from toxicity exposure at their work places (Greim, & Snyder, 2008... )....
