The Molting Process for Insect Growth

Molting,  known technically as ecdysis, is literally a period of growth for insects. In humans, an analogy can be drawn to molting as a period of personal transformation, such as the shedding of ones old self and the emergence of a new and improved person. Insects grow in increments. Each stage of growth ends with molting, the process of shedding and replacing the rigid exoskeleton. People often think molting is the simple act of an insect breaking out of its skin and leaving it behind. In truth, the process is complex and involves several parts. When Insects Molt After egg hatches, the immature insect feeds and grows. Its exoskeleton is like a shell. Eventually, the larva or nymph must shed its unyielding overcoat to continue its development. The exoskeleton which serves as its  external backbone is used for protection and support. Without an  exoskeleton, the insect could not survive. An old exoskeleton is shed when a new one is ready underneath, a process that can take days or weeks. Understanding the Exoskeleton To understand how molting occurs, it helps to know the three layers of the insect exoskeleton. The outermost layer is called the cuticle. The cuticle protects the insect against physical injury and water loss, as well as provides rigidity for muscle. It is this outermost layer that sheds during a molt. Underneath the cuticle is the epidermis. It is responsible for secreting a new cuticle when it is time to shed the old one. Underneath the epidermis is the basement membrane. This membrane is what separates the insect’s main body from its exoskeleton. The Process of Molting In molting, the epidermis separates from the outermost cuticle. Then, the epidermis forms a protective layer around itself  and secretes chemicals that break down the insides of the old cuticle. That protective layer becomes part of the new cuticle. When the epidermis has formed the new cuticle, muscular contractions and air intake cause the insect’s body to swell, thus splitting open the remains of the old cuticle. Finally, the new cuticle hardens. The bug squeezes out from the outgrown exoskeleton. The insect must continue to swell and expand the new cuticle, so it is large enough to allow room for more growth. The new overcoat is soft and much paler than the former one, but over a few hours, it becomes darker and begins to harden. Within a few days, the insect appears to be a slightly larger copy of its former self. Pros and Cons of Molting For some insects, a  big benefit to having a system of molting for growth is that it allows damaged tissue and missing limbs to be  regenerated  or substantially reformed. Complete regeneration may require a series of molts, the stump becoming a little larger with each molt until it is a normal or nearly back to normal size. A  major disadvantage to having to molt  as a system of growth is that the animal in question is entirely incapacitated during the process. An insect is completely vulnerable to a predator attack while undergoing molting.

Amending the Second Amendment - 1083 Words

On December 12, 2013, a heavily armed man walked into a small elementary school in Connecticut and opened fire, ending the lives of 26 children and teachers, not only shattering the quiet of the small town but leaving our nation lurching at the number of young lives lost. The horror of this event renewed people’s passion on both sides of the fiercely debated issue of gun control and brought the issue to the forefront of American politics once again. While no new gun control laws have been passed since this tragedy, the debate over how to interpret the 2nd amendment continues. Gun control laws are the government’s way of regulating the manufacture, sale, transportation, possession, and use of firearms. In our world today, we face the vast controversy of gun control and who should be able to possess a destructive firearm, and under what conditions. These laws differ significantly around the world, and in fact the laws in the United States vary by state. Supporters of strict gun laws argue the dangers of allowing citizens broad rights to possess firearms. Opponents claim that they wish to have a source of defense in their home, and also that certain regulations may violate their individual rights. Gun control laws are protected by the second amendment in the Bill of Rights, the right to bear arms. â€Å"A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.† The bill guarantees Americans theShow MoreRelatedThe Resolved Issue Of The Constitution Essay1457 Words   |  6 Pageswith the federal constitution.† (U.S. Constitution, Encyclopedia of American Law and Criminal Justice, Revised Edition) The process that takes place to change or add an amendment requires, the amendment to start with in the house of representative such as the senate or the congress.

EST1 – Ethical Situations in Business A small local grocery stores disadvantages in a metropolitan areas EST1 Task 1 Being a small, local grocery store chain in a major metropolitan area does not come without its challenges. National and regional chains are frequently forcing small and locally owned stores to close their doors. For this reason, as well as the huge obligations to the social responsibilities required by their communities and customers alike pushes both the small business owner as well as the larger corporations to be able to adjust their organizations goals and objectives to balance not only their goal to be profit driven but to also be socially and ethically perceptive with the way they conduct business and operate their stores. We will write a custom essay sample on Est 310.2.1-05 (Company Q) or any similar topic only for you Order Now Recently Company Q has chosen to close two store locations that operated in areas where crime rates were statistically higher within the city. The store closures are being driven by consistent losses the stores experienced year over year. If the stores have consistently lost money year over year, we need to analyze the reasons as to why. To take the social responsible approach at analyzing this question; we would first need to understand our customer demographic for each of the geographical locations. For example, if one of our stores is located in a highly populated Hispanic neighborhood and we are promoting Ethnic Asian foods, we could not expect these foods to sell at the same rate as we would handmade corn tortillas. Taking an ethical and cultural marketing approach to sell foods that are Hispanic-centric strongly supports the business and ethical approach that would be needed for our store to successfully show a profit. When we stop to understand our customer demographics and their communities in which they live, we then can recognize what is needed for our business to prosper within the community. After many years of customer requests Company Q, began offering a limited selection of health conscience and organic products in their stores. Offering organic and environmentally friendly products in response to our customers’ requests is a large step in forming a social contract with our customers instead of merely offering then what we feel they need. Soliciting feedback from our customers provides us with the means to understand what they want and what they need. Offering a high end products to our customers that neither have the financial ability to afford the high costs that accompany high end products, nor do they have the desire to purchase these products to help Company Q’s bottom line. In fact it will actually drive our results in the opposite direction. Our product choices must be targets to the consumer within our communities. Ethnic foods must be customary to the neighborhoods in which they are being offered. The marketing of our stores in cultural or racially specific communities must be stocked with the products that meet the needs of our customers in those communities. It takes very minimal effort to understand our customers, but that minimal effort makes the difference between a store being successful or failing. There are multiple sources that can be used to help us understand our customer’s cultural and social desires. To gain a simple understanding of the cultural needs for a Hispanic – centric neighborhood can begin with a simple Google search on Hispanic Market Research. For example when preforming the following Google search we learned. â€Å"Market Research Hispanics† â€Å"According to the U. S. Census Bureau, the terms Hispanic (and Latino) refer to people â€Å"whose origins are from Spain, the Spanish-speaking countries of Central or South America, the Caribbean, or those identifying themselves generally as Spanish, Spanish-American, etc. Origin can be viewed as ancestry, nationality, or country of birth of the person or person’s parents or ancestors prior to their arrival in the United States. † Hispanics can be of any race. There are more than 48 million Hispanics in the United States. Latinos now account for 16% of the American population. The 32 million Latinos of Mexican origin account for around 66% of the Hispanic population. Hispanics accounted for more than half of all of the growth in the U. S. population that occurred between 2000 and 2009. Latinos also are expected to be responsible for more than half of the growth in the U. S. population between 2010 and 2015. With an estimated buying power of $616 billion, Latinos of Mexican heritage represent the single most influential segment of the Hispanic market. Mexicans in the United States account for 59% of all Hispanic buying power. On a per capita basis, however, Cubans are the most affluent of the major Hispanic population segments. Their per capita buying power is substantially higher than that of Mexicans ($32,724 vs. $19, 426). The vast majority (92%) of Hispanics under 18 were born in the United States as were about 47% of those 18 and over. Mexicans are most likely to be U. S. -born. More education leads to higher-paying jobs and increasing affluence among high-acculturation Latinos. High-acculturation Hispanics are more likely than their low-acculturation counterparts to work as managers and professionals (19% vs. 6%). They are twice as likely to have a household income of $75,000 or more (37% vs. 19%) and are much more likely to own their home (62% vs. 40%) (Census Bureau, 2012 www. marketresearch. om ). † Preforming a simple marketing search on the Hispanic cultural give us insight as to how we can begin to market and set ourselves apart in the marketplace. How we can currently target and begin to build a marketing strategy that will ensure the future growth and the economic sustainability of our stores within a Hispanic – centric neighborhood. Currently Company Q operates under the policy of disposing of day-old products, this a perfect example where our management team is missing out on a great public relations and corporate social responsibility opportunity. When approach by the area’s food bank to donate day-old products that would otherwise been thrown away, our management team declined. Management being more focused on the possible loss of revenue due to the potential increase in fraud and stealing that could be done its employees who could claim that that they were donating the food. One thing that we need to understand it the actual cost associated with and or the actual / perceived benefits. Our company will write –off any product that needs to be disposed of due to the shelf life expiration date. The products are disposed if in a dumpster and therefore currently ends the usefulness of the product from the company’s perspective. If we are paying for the products by weight or volume, we will incur a greater disposal rates from the waste removal company for the disposal of those unsellable products instead of donating them to a local food bank. This concern of a possible increase in expenses does not begin to look at the tax benefits that could be received by the donating of the product to a local food bank as well as other possible economic impacts that this policy can have on the economy of our community. Another concern that we need to be aware of is the impact that our policy to throw away on day-old products will have on employees moral. If we’ve communicated to our employees that we will not be socially contentious to our local communities, then what is the message that we are delivering to our employees since they are part of our communities. How will they relate that to how valued they feel as an employee for Company Q? In our technology and media driven society it would e foolish not to except a socially aware employee or customer to film the disposal of the food that we may have not been able to sell, but it could easily be donated to our local food banks to help those in need. The potential of the negative publicity and feedback from such an event would be devastating to a small chain stores such as ours. The above mention concerns addressed not only some of the potential financial impacts but also the possible social capital losses that we could face in our current po sition. Thankfully, we do not need to pay out much financially or in employee efforts to make a substantial difference in our stores and neighborhood communities. One delivery van can be used at the end of each day to deliver the products that would have otherwise been thrown away to our local food bank. The food can be unloaded by the food bank staff while the food bank manager shares with the Manager or Supervisor of our company the impacts that this donation will have on the community. This same information can be taken back and share with the store employees. The minimal time spent delivering and unloading the products daily at the local food banks in a minor change in the daily operations for the store, but will have an overall impact to the community that will consistently strengthen our relationship within in the local communities, our relationships with our employees as well as enhancing our brand across our chain of stores.

Why Prohibition is Not the Answer free essay sample

Examines the case for drug prohibition against the backdrop of the historical examples of alcohol and cigarette prohibition, arguing that complete prohibition is unlikely to succeed today. This paper addresses the common question in public policy on how best to restrict the proliferation of addictive substances in society: drugs, alcohol and cigarettes. The author examines the policies ranging from complete prohibition to the legalization of non-addictive drugs. This paper draws on the historical examples of alcohol and cigarette prohibition to argue that the complete prohibition of drugs is not the best answer to the drug problems faced by significant numbers of Americans. Many legislators advocate the prohibition of addictive substances as the best way to limit their consumption and the myriad social and economic ills that accompany it. This zero-tolerance ideal was the basis of the noble experiment of alcohol prohibition during the 1920s, the ban on cigarettes in Canada and 15 American states at the beginning of this century, and, perhaps most pertinently, the War on Drugs that we currently find ourselves embroiled in. We will write a custom essay sample on Why Prohibition is Not the Answer or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Drawing primarily on the ideas formally presented by Chester Barnard, this paper will dissect the historical example of alcohol prohibition in the 1920s in order to demonstrate that prohibition is a poor approach towards tackling the consumption and sale of harmfully addictive substances because of the manifold obstacles to implementation that stand in the way of its success.
