Whelk Facts and Information

Whelks are snails with beautiful shells. If you see something on the beach that looks like a seashell, its probably the shell of a whelk. There are over 50 species of whelks. Here you can learn about characteristics common to these species. What Does a Whelk Look Like? Whelks have a spiraled shell which varies in size and shape. These animals can vary in size from under an inch in length (shell length) to more than 2 feet. The largest whelk is the trumpet whelk, which grows to over 2 feet. Whelk shells vary in color. Whelks have a muscular foot that they use to move and hold prey. They also have a hard operculum that closes the shells opening and is used for protection. To breathe, whelks have a siphon, a long tube-like organ which is used to bring in oxygenated water. This siphon allows the whelk to burrow in the sand while still getting oxygen. Whelks feed using an organ called the proboscis. The proboscis is made up of the radula, esophagus, and mouth. Classification Kingdom: AnimaliaPhylum: MolluscaClass: GastropodaOrder: NeogastropodaSuperfamily: BuccinodeaFamily: Buccinidae (true whelks) There are additional species of animals that are called whelks but are in other families. Feeding Whelks are carnivores, and eat crustaceans, mollusks, and worms—they will even eat other whelks. They can drill a hole into the shell of their prey with their radula, or may wrap their foot around the hinged shells of their prey and use their own shell as a wedge to force the shells open, then insert their proboscis into the shell and consume the animal inside. Reproduction Whelks reproduce by sexual reproduction with internal fertilization. Some, like the channeled and knobbed whelks, produce a string of egg capsules that maybe 2-3 feet long, and each capsule has 20-100 eggs inside which hatch into miniature whelks. Waved whelks produce a mass of egg capsules which look like a pile of egg cases. The egg capsule allows the young whelk embryos to develop and provides protection. Once they have developed, the eggs hatch inside the capsule, and the juvenile whelks leave via an opening. Habitat and Distribution The question of where to find a whelk depends upon what species youre looking for. In general, whelks may be found in many parts of the world, and are usually found on sandy or muddy bottoms, from shallow tide pools out to waters several hundred feet deep. Human Uses Whelks are a popular food. People eat the mollusks muscular foot—an example is the Italian dish scungilli, which is made from a whelks foot. These animals are also collected for the seashell trade. They may be caught as bycatch (e.g., in lobster traps), and they may be used as bait to catch other marine life, such as cod. Whelk egg cases may be used as a fishermens soap. The veined rapa whelk is a non-indigenous species that have been introduced into the U.S. The native habitat of these whelks includes waters in the western Pacific Ocean including the Sea of Japan, Yellow Sea, East China Sea, and the Bohai Sea. These whelks were introduced into the Chesapeake Bay and may cause damage to native species. Sources Conley, C. Whelks. Edible Vineyard. Issue 6, Early Summer 2010.Whelks.

Android Os Security Advantages and Disadvantages

Android OS Security: Advantages and Disadvantages In the field of computing, few inventions, innovations or technological improvements, have been moving quite like wireless technology. With the advent of fourth generation cell phones and networks (4G), there have literally been leaps and bounds made in the realm of personal computing, productivity and data sharing. It is this increased connectivity both in our personal and business lives that introduce risks to intrusion, corruption or theft of data, or in the worst case, access to personal data that would lead to identity theft.

Additionally, it seems that a large number of applications use multimedia, location, and/or private information suspiciously. In an exa mple of this, 30 random applications from the Android Market were tested and half of these used information suspiciously (Enck, 2010). Considering this information, it is further troubling that research has indicated as many as one-third of applications seek permissions that are greater than are actually needed (Chin Felt, et al, 2010).

Job Satisfaction and Organizational Commitment

Question: Have influence on the nature and process of the change. Respect the person who is championing the change. Expect the change will result in personal gain. Answer: To elicit positive reactions, the ABC Organization should adapt to change based on job satisfaction and organizational commitment. These work related components need to focus on different areas like communication, principal support and management competence (Vakola, Armenakis Oreg, 2013). However, to achieve positive responses it is important that there should be compensation involved with a change in job design and a focus on well-being. The change undertaken will lead to stimulate responses by changing beliefs and instilling coping behaviors in the organization to have a pleasantness reaction (Petrou, Demerouti Schaufeli, 2015).

Theory of Knowledge Essay Summary Example For Students

Theory of Knowledge Essay Summary Other examples include: blindness preventing one from seeing things, Deafness preventing a person from hearing. Overall, our senses have a lot of room for inaccuracy in countless situations. However with technology there are alternative ways to work around these impedes. Such as using a thermometer to give accurate readings of the temperature instead on guessing what the temperature might be. However, all of these ideas do not necessarily mean we should never rely on our senses. Many of us are able to recognize if a storm is about to begin, or even if its going to rain soon.

I my self has done with several times while traveling and didnt have access to a weighing scale. Senses can also be the right answer when in a situation where one has to take sudden actions. Be it in a volleyball game when the player has to decide which way to play the ball or deicing whether to eat apple that looks dirty and poisoned. Since we cannot base all our opinions and judgments solely on senses, reasoning plays a key role in determining truth. We use our senses to determine that a given phenomena occurs, and reasoning to determine why that phenomena occurred. Reasoning is evident especially in mathematics and the sciences. For example, Gregor Mendel observed the patterns visible in generations of organisms. Mendel then conducted experiments in which he cross-pollinated several varieties of pea plants and discovered that genetic traits are passed between successive generations in specific and regular ratios. Using those ratios, he formulated the laws of heredity, which enable us to predict which traits, and in what proportions, will show up in a particular generation, based upon the traits that have appeared in preceding generations. Using this experiment we can draw to a close that the sole use of senses without reasoning is not sufficient evidence of truth, and reasoning without the use of senses is incomprehensible; if we were to not use or trust our senses at all, we would have observed or obtained nothing to reason in the first place. In conclusion, our five senses sight, smell, taste, touch, and hearing are critical in observing the world around us and interconnecting the various ways of knowing. The brain constantly uses reasoning to apply meaning to the observations made through the use of our senses. However, one should acknowledge hat there are certain situations in which our senses can lack accuracy. We should not be quick to trust our senses when they conflict with each other, when they conflict with another individuals senses, or when they are being degraded by external factors. However, we should certainly trust our senses to give us knowledge and truth when we can back them up with sufficient reasoning or experience. Therefore, it can be said that all known truths have been obtained through the use of senses together with reasoning. We should trust our senses to give us truth only when the knowledge we obtain is public, independent of anyones belief, eternal, and can be justified with reasoning.

Carol Ann Duffy Midas and Aesop Essay Example

Carol Ann Duffy Midas and Aesop Essay Mrs. Aesop In Mrs Aesop, Duffys speaker does more than regret a loss; this time, her tone is resentful that the man she married has turned out to be an Asshole. Mrs Aesop relies on the readers foreground knowledge that Aesop (a Greek slave) was a literary genius responsible for inventing the allegorical mode; this is the worlds preconceived view of him. By contrast, his wifes starting-point is that, no matter how entertaining and instructive Aesops fables are, the man himself is a bore and, whats more, boring (Tedious) because, if he isnt busy researching his next tale, hen hens talking at her in the didactic language of the last one. The racy, vernacular rhythms of Duffys free verse And thats another thing, the sex was diabolical are ideally suited to express both her rhetorical indignation at his pious lecturing and her deeper frustration at his inadequacies; to illustrate his sexual impotence, she concocts her own fable about a little cock that wouldnt crow.

Mrs. Midas In Mrs Midas, Duffys imagined speaker is the wife of Midas, King of Phrygia to whom Dionysus granted his hamartic wish that everything he touched should turn to gold. Duffys strategy is to chart the stages by which it dawns on Midas wife first that her husband possesses this golden touch and second that it has potentially fatal consequences: lt was then that I started to scream. King Midas fatal flaw is his asculine sense of priorities according to which material satisfaction appears more important than emotional/spiritual fulfilment; her dramatic realisation of his folly Mrs Midas records by her exercise of a grim wit at her husbands expense. In the situation, she discovers that metaphorical expressions (near petrified/ when it comes to the crunch/ heart of gold) have recover ed their literal meanings. The best of these verbal gags she saves for the final verse-paragraph: What gets me now is not the idiocy or greed but lack of thought for me. Pure selfishness. The poem is a criticism of male selfishness: if it is pure selfishness, then in the particular circumstances it is 24-carat selfishness. Mrs Midas, however, is not misanthropic; her tone is of regret that she has lost the man she loves and her final sentiment is a wistful longing to have him again: I miss most0even now, his hands, his warm hands on my skin, his touch. The ultimate irony is that Midas possessed a magic touch all along: namely, the physical touch which had the power to transform her into a loving wife.

Immigration in the United States Essay Example | Topics and Well Written Essays - 1500 words

Immigration in the United States - Essay Example Once immigration was taken for granted in the US policy but now, immigration policy occupies a significant space in the political agenda of both, the democrats and the republicans. This paper will explore the perspectives of the various segments of the society like employers, US Citizens and immigrants on the immigrations policies and its altogether impact on the US Immigration Policy, while discussing this, we will also analyze the propaganda used by both the political parties. The employers have always been the keen advocates of the policies in the favor of the immigrants. It is so because; these immigrants ensure the constant supply of the cheap labor. (Katel 2005)They are usually willing to work at lower wages and perform those activities which the US residents don't want to perform like working the farms, restaurants, gas stations etc. That's why; especially the states like Texas and Arizona are strong advocates of the immigrant - favoring policy. (Arizona Secretary of State Proposition 200)Thus it is quite obvious, higher the influence of these employers on the government, the more immigrant favoring policies are expected. Their most strong argument is the fact that cheap labor supply ultimately reduces the cost and thus benefiting the society in general. The US citizens, on the contrary, argue that though it... igrants are engaged with, but the additional burden on tax payers, in order to provide the public utility services to those immigrants is far higher than the reduction in cost.(Kelly 2005) Moreover, they also argue that immigrants are the continuous threat to their employments and above all, their security. The later apprehension has been boosted up sharply in the post 9/11 scenario and the political factions advocating strict immigrant policy used this 'fear factor' to propagate and convince the legislators for constringent immigration policy. Position of President Bush and Current Administration When George W Bush became the president, the illegal immigration was at height and none of the constitutions were able to deter the influx of illegal immigrants. The situation called for a constitutional reform to address the issue. The 9/11 attacks and then the 9/11 commission's report in 2004 highlighting "systemic weaknesses" in border-control and immigration systems, further strengthened the need. All this led to the formation of the 'Fair and Secure Immigration Reform Guidelines'. These guidelines formed the basis of the Comprehensive Immigration Reform. That was further reiterated in Bush's statement of Nov 28, 2005 on 'Securing America Through Immigration Reform'. Comprehensive immigration reform has three major parts: Securing the Border Improving Enforcement of Immigration Laws within The United States Creating a new Temporary Worker Program http://www.immigrationreformnow.org/immigrationreformnow/#CIR Position of Republicans and Democrats: The republicans and the democrats represent two separate ideologies. Democrats believe in helping people of the world and thus expending this support even to the non-Americans. This fundamental ideology makes it obvious
