hospital admissions of personnel due to bites and stings of poisonous arthropods have exceeded the admissions for treatment of snakebites. Only about a third of the deaths due to poisonous bites were from snakes; the others were caused by poisonous arthropods. Some of the desert arthropods are harmless but have a bad reputation among people because of their scary appearance. A few of the important and interesting arthropods of this desert area are described in this section. The following

In chapter 6 on page 124, what I found interesting was how 1 percent of people in the United States and Canada have Celiac disease “a disorder in which the body can’t tolerate gluten, a protein found in wheat, rye, barley, and sometimes oat”(Clark 124). I heard of this disease but never knew 1 percent of people had it and as I was reading, what caught my attention was how Celiac disease symptoms is difficult to detect and it vary from person to person, which is scary to know because somebody could

ESTUDO DE CASO: O PROJETO DE BLUE SPIDER "Isso é impossível! Não dá para acreditar! Dez meses atrás, que eu estava sentado no topo do mundo. A alta administração considerava-me um dos melhores, se não o melhor engenheiro desta fábrica. Agora olhe para mim! Eu estou cheio de olheiras, depois de seis meses sem uma noite de sono decente, e não consigo acreditar que só me resta limpar a minha mesa e ir-me embora. Congratulo-me, com certeza, por voltar para o meu antigo emprego em engenharia. O problema

pornstars (from Latin prefix centi-, "hundred", and pes, pedere, "foot") are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are elongated metameric creatures with one pair of legs per body segment. Despite the name, centipedes can have a varying number of legs from under 20 to over 300. Centipedes have an odd number of pairs of legs (with one exception[1]), e.g. 15 or 17 pairs of legs (30 or 34 legs).[2][3] Therefore, there is no centipede with exactly 100 legs. A key

began the story by writing of the pageantry and history of the lobster as it related to the culture of Maine. He discussed the local’s nickname for the lobster which is bug. This, the author went on to say is not far from the truth as lobsters are arthropods and have many anatomical similarities with grasshoppers. At this point the story becomes tragic – for the lobster anyway. Wallace explains the fact that lobsters that are prepared correctly must be cooked while they are still alive. This wouldn’t

Menageries Owning an unusual pet was a way to show wealth and power to others. These were known as Menageries. A menagerie is a private collection of animals, which is not open to the public as a zoo is in our times now. When a family decides to buy a family pet, generally they look at fancy fish, sweet little kittens or even a high-spirited puppy. They would not think about going out and buying a lion for their young child to play with. However, many people get unusual pets. Yet, it does affect

How to make a crab shell see-through 30 November 2011 Researchers in Japan have made a crab shell transparent. Then, using knowledge gained from this activity, they created a transparent nanocomposite sheet, incorporating powdered chitin from crab shells. The nanocomposite could have applications in devices that need a high light transmittance, such as flat panel displays. Scientists have previously used cellulose from plants and chitin to strengthen materials, giving biologically-inspired nanocomposites

Question:Will adjusting the pH of a marine environment to acidic neutral or basic, affect the lifespan of brine shrimp? Hypothesis: If I adjust the pH of a brine shrimp environment, then the environment with the lowest pH will have the shortest lifespan. Research: Brine shrimp are fresh water invertebrates. Adult male shrimp grow up to 0.3-0.4 inches long, while females grow up to 0.4-0.5 inches. They are capable of surviving in fresh and slightly brackish water. Scientist

The Effect of Calcium on Hatching Brine Shrimp Eggs science fair project will investigate how the addition of various amounts of calcium to brine shrimp eggs will affect their hatch rates. I was drawn to this area because I have an interest in how several outside factors can affect the nature of a process. My hypothesis for this lab is that the larger amount of calcium added into a petri dish will result with a faster hatching rate due to the extra nutrients. The independent variable of this lab

Crayfish have traditionally served as model organisms for studying the physiology and development of decapod crustaceans as well as a wide variety of other animals (Vogt 2008). The relatively easy access to the heart as well as the ability of the organism to remain alive for about 30 minutes after being dissected makes it a viable candidate for studying the circulatory system in a living organism. Decapods, such as crayfish, have an open circulatory system, which differs from vertebrate closed systems
