Beetle Research Paper free essay sample

Some studies and experiments have shown that population growth can be followed with the flour beetle (Tribolium confusum). Studying these beetles for over a month in varying habitats showed there was a dramatic increase in the populations with larger quantities of food, and a much slower growth rate with more space and the space amount of food. The experiment that I conducted provides a direct correlation between the roles of space and food in a controlled study of these differing populations. Thomas Malthus, in the year 1798, found that varying populations of both plants and animals are geometrically progressive. Populations increase exponentially, while food supplies increase at approximately the same rate. Because of the progression, any animal or plant could spread over most livable places; however, populations of species remain at a constant level because of death and therefore do not grow indefinitely. Also, there is something in place that restricts population growth (Malthus 1798). We will write a custom essay sample on Beetle Research Paper or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page To test Malthus’s statement the Tribolium confusum, or confused flour beetle can be used for certain hypothesis and predictions that test limiting factors, such as food and space. The Tribolium confusum are functional specimens for a study of these limiting factors because of the growth rate. The growth period of these particular beetles are relatively fast. After approximately 5-12 days of fertilization, the egg hatches into larvae. The larvae last 22-100 days and the pupae last around 8 days (Brereton 1962). These beetles are easy to examine, because they can thrive off of flour with very little moisture, and vermiculite can be used to create space. The life span of the Tribolium confusum tends to last around 200 days; our experiment takes place within that time limit. Hypothesis: Hypothesis 1: The amount of food is a limiting resource for the population of the Tribolium confusum. Hypothesis 2: The amount of space is a limiting resource for the population of the Tribolium confusum. Predictions: Prediction 1: I predicted that the more food that Tribolium confusum had the more the population will grow. I predicted that the more space Tribolium confusum had the more the population would grow. Methods and Materials: To test whether food or space are limiting factors on population growth, our lab group created different artificial habitats for Tribolium Confusum thrive. For the experiment 6 different treatments where created. In this experiment we used 6 different half pint, large opening mason jars. All of these jars were the same size, and contained different amounts of food (corn flour) and livable space (vermiculite + flour). A measurable amount of corn flour and/or vermiculite were added to each jar.

Free Essays on Firestone

Firestone tires could have avoided many of their legal and public relations problems if they’d used the template Johnson and Johnson established in the 1982 Tylenol scare. That’s the conclusion reached by Bob Garfield in an article in the August 28, 2000 issue of AdAge. The author compares the similarities of the problems both companies faced, and the differences in the recovery process Johnson and Johnson took in the Tylenol scare versus what Bridgestone/Firestone is doing to combat the negative publicity, and regain their customers’ trust. In October 1982, several individuals died as a result of Tylenol capsules contaminated with cyanide. In an effort to save lives, Johnson & Johnson, the makers of Tylenol, recalled every single bottle in the country, no matter whether they were on the store shelf or your bathroom shelf. They also shut down all production and distribution of the medication. Johnson & Johnson publicized the recall with full-page newspaper ads and stories on the news. They had an open policy and were willing to answer any questions at the expense of their good name. As stated in the article, it was a public relations nightmare for the company, but Johnson and Johnson had a â€Å"quick and thorough response†, and the public’s appreciation of its honesty and an expertly handled ad campaign helped retain most of their customers. Unlike J&J, Firestone’s initial reaction to their nightmare did not inspire public trust. A couple of years ago, when dozens of people died in Ford Explorers equipped with Firestone tires, the Bridgestone/Firestone Corp. did not launch an ad campaign to inform, and regain the trust of the public. Instead they launched a mudslinging campaign against Ford that ultimately resulted in the termination of their 100 year old business relationship. In fact, because of their slow action and ne...

Maldoror by Comte de Lautreamont - Essay Example He himself shifts into various animal forms and sees people do the same. He wants people to embrace the base, vile animal within themselves in order so that they will become evil too. Animals live by their appetites, they have no higher reason or calling. Maldoror wishes to see humanity reduced to this base form. He transfers into animal form to escape his disgust for humanity. It is easy to sense the poet's own disgust with humanity. He clearly is unhappy with human hypocrisies and sees in the animal kingdom something that is purer or freer of guile. He sees an insect as a beautiful thing, not as something disgusting. This is worthy of note. Few works in the history of literature have made as much of an impression as this one. Its non-narrative structure and powerful imagery influenced a generation of surrealists. But it also contains a larger, almost theological message: We should value the distinction between us and animals.
