Chondrichthyes vs Arthropod
The black widow is most easily recognized by the hourglass marking on the underside of its abdomen. When bitten, a neurotoxin is released that can cause dull pain and cramping in muscles, that can be accompanied by sweating and vomiting. Less than 1% of black widow bites result in death.
Black widow spiders are usually not aggressive. If disturbed, they will retreat to a corner of their web. These spiders are more aggressive if they are protecting an egg sac. The natural habitat of a black widow is outdoors, under rocks, brush or piles of debris. Indoors, these spiders can usually be found behind furniture, in storage boxes, etc.
A black widow's eyes are on top and near the front of its head. They have 8 eyes, arranged in 2 rows of 4 each. Some spiders have better vision than others. For example, hunting spiders have good eyesight at short distances. Their eyesight enables them to form images of their prey and mate. Web-building spiders (the black widow) have poor eyesight. Their eyes are used for detecting changes in light.
A black widow's mouth opening is bellow its eyes. It does not have chewing mouth parts, and they eat only liquids. Various appendages around the mouth opening form a short "straw" through which the spider sucks the body fluid of its victim. The black widow can eat some of the solid tissue of its prey by predigesting it. To do this, the spider sprays digestive juices on the tissue. Chelicerae are a pair of appendages that the spider uses to seize and kill its prey. The chelicerae are above the mouth opening and just below the spider's eyes. Each chelicera ends in a hard, hollow, pointed claw, and these claws are the spider's fangs. An opening in the tip of the fang connects with the poison glands. When the black widow stabs an insect with its chelicerae, poison flows into the wound and paralyzes or kills the victim. The fangs of tarantulas point straight down from the head, and the poison glands are in the chelicerae. In the black widow, the fangs point crosswise, and the poison glands extend back into the cephalothorax. They also crush thier prey with their chelicerae.
Pedipalpi are a pair of appendages that look like small legs. One pedipalp is attached to each side of the spider's mouth, and they form the sides of the mouth.
…the world is like an enormous spider web and if you touch it, however lightly, at any point the vibration ripples to the remotest perimeter and the drowsy spider feels the tingle and is drowsy no more but springs out to fling the gossamer coils about you who have touched the web and then inject the black, numbing poison under your hide.(188-89)

The spider’s web is in a corner connected to the tile wall to wile wall and floor, in such a usual spot and it was miraculous that it kept her alive. The miracle she celebrates through out the essay is the death of the moth you once helped killed as the spider killed the sixteen moths who lay behind her toilet.
Mark Twain’s Adventures of Huckleberry Finn is considered the great American Novel with its unorthodox writing style and controversial topics.

This paper will analyze a passage from Adventures of huckleberry Finn and will touch on the basic function of the passage, the connection between the passage from the rest of the book, and the interaction between form and content.
Oxygen is vital to a beating, healthy heart because it is needed to perform cellular respiration in order to pump the blood. When there is no oxygen being transported to the heart, the heart cannot pump blood, and eventually after being inactive, the heart tissue dies . This results in a heart attack. Heart attacks can be diagnosed before it is too late. One method of diagnosis is through a blood test. Blood tests are capable of sorting through the material found in blood, and if heart cell contents are found in the specimen, a heart attack can be diagnosed. If the levels of the cell contents are higher, this signifies that the heart attack is more severe. Another method of diagnosis is an electrocardiogram (ECG). An ECG measures the rhythm of the heart in order to detect defects. There are many other strategies that are used by doctors in order to diagnose a heart attack, such as chest x-rays, stress tests, tilt table tests, and echocardiograms, to name a few. A myocardial biopsy involves looking at the heart cells, and is accomplished by collecting a sample of heart cells from the patient. If the results are positive, a heart attack is diagnosed. A heart MRI involves looking at images of the heart in order to detect heart failure. The doctor uses the images to look for disorders in the structure of the

Anorexia Nervosa (AN) was the first eating disorder to be classified, with some specific diagnostic criteria developed in the 1970s (Fairburn & Brownell, 2002). AN is a serious psychiatric disorder in terms of aetiology and epidemiology. 0.48% of prevalence of AN is estimated in girls who fall under the 15-19 age group (Lock et al., 2012). In AN, pathological thoughts and behaviours concerning food and weight, as well as emotions about appearance, eating and food co-occur (Lock et al., 2012). These thoughts, feelings and behaviours lead to changes in body composition and functions that are the direct results of starvation (Lock et al., 2012). The illness in adolescents causes severe affects physically and emotionally, and affects the social development of the individual. The causes of AN are not known but most of the researchers and clinicians agree that AN has multiple determinants (Garner et al., 1982) that emerge in a developmental sequence. Many physiological symptoms, common to semi-starvation irrespective of causes such as depressed mood, irritability, social withdrawal, loss of sexual libido, preoccupation with food, obsessional ruminations and rituals, as well as reduced alertness and concentration are also associated with Anorexia nervosa (Fairburn & Brownell, 2002). The illness is also associated with premorbid perfectionism, introversion, poor peer relations, and low self-esteem (Fairburn & Brownell, 2002). Patients suffering from AN, are also known to suffer from other physical consequences of starvation and other weight losing behaviours. The body’s response to starvation includes bone marrow suppression with increased susceptibility to overwhelming infection, which in the longer term may lead to health consequences s...
An asp bite creates a particularly awkward, excruciating death. The asp venom causes blood poisoning and an intense burn at the site of the wound. This burning is quickly forgotten, however, as the bite victim fades into a state of giddiness accompanied by nausea and extreme thirst. Blood clots form as the skin becomes speckled with purple spots, and there is usually a considerable amount of swelling. The victim then goes into convulsions, vomiting, urinating, and defecating uncontrollably (Hughes-Hallet 106). This is not a death suitable for a Queen, let alone Queen Cleopatra. Nonetheless, writers throughout history have designated the asp to be Cleopatra's suicide weapon. Her death is described as either an ecstatic orgasm or a serene slip into eternal slumber. Analyzing her death with an eye for accuracy, we can see that it is highly unlikely that Cleopatra would have chosen to kill herself with an asp. "Asp" is an imprecise term, which referred to many various African vipers, all of which would have left her corpse looking less than beautiful. The death that Cleopatra is described to have experienced resembles the death caused by a cobra sting, not an asp bite. A cobra would have had to be at least four feet long to excrete enough venom to kill Cleopatra and her two maids (Hughes-Hallet 107). Since writers have taken liberties with their descriptions of Cleopatra's death scene, representing the asp in various ways, we should ask, "What does the snake symbolize in Cleopatra's suicide, and how does this representation affect the overall portrayal of the Queen and her suicide?"
... in the form of poor and humble people". Arachne had already done enough damage by openly saying that her skills were equal to or possibly even better than a goddess's, but to continue to insult Athena by weaving such a pattern in to her cloth was taking it too far. In the end Athena turns Arachne into a spider and dooms her and her descendants to continue to weave.
The tarantella has a very interesting history. Its name derives from a little southern town of Italy called Taranto. It was believed that if a spider called the tarantula bit the townspeople, the only way to survive its bite was to do a dance called the Tarantella. The locals believed this was the only cure. If the people bitten did not dance they would suffer severe pain, muscle spasms, vomiting; most eventually died.

Arachnida is a subphylum of Arthropoda, consisting of over 100 000 species, many of them being parasites which can carry disease. They are found in all environments, and mostly have eight legs, which is a feature, together with the fact that they do not have wings or antennae, often used to distinguish them from the other subphyla, though there are exceptions. They include spiders, scorpions, ticks and mites. Their bodies are divided up into three parts: the cephalothorax, the opisthosoma and the thorax, and use a type of lung for gas exchange. Most Arachnids are carnivorous, and eat pre-digested insects and other small animals. They reproduce using internal reproduction usually lay eggs, except for the scorpion which bears living young. The word ‘Arachnid’ comes from the Greek word ‘Arachne’ meaning ‘spider’.
2. The poem starts off with a white spider on a white heal-all which holds onto a white moth. Just the knowledge of knowing that it is a spider, not to mention a fat spider, it has a negative connotations because no one really likes them to be honest. Spiders symbolize death and mystery. As for the heal-all, it is a plant that is commonly used for medicinal purposes. The rhyme scheme and vowel sounds emphasized that they are ‘characters of death and blight.’
Being a teenager is difficult in it of itself. Some teens find it easy to take their frustrations out on other people. This is when teen violence arises. Bullying is one of the most popular forms of teen violence in today’s schools and can affect the victim emotionally, physically and mentally. To make themselves feel better, the bully will physically abuse their victim, or verbally abuse them by calling them names or starting rumors about them. According to Dan Olweus, author of “Bullying at School”, the typical victims of bullying are anxious, insecure, quiet and sensitive. They...
Bullying hurts the person being bullied in tremendous ways ("Bullying"). Children that are bullied sometimes feel hated, unimportant, and terrified ("Bullying"). Children that are bullied wake up everyday knowing that the bullies are waiting to torture, embarrass, and hurt them (Wright). More than 43 percent of middle-school and high-school students avoid using school bathrooms because they are scared of being messed with or hurt (Havenrich). Kids who are bullied can gain physical symptoms like headaches, stomach pains or sleeping problems (“What Effects”). Some kids are physically injured and they are left with bruises, black eyes, broken bones, internal injuries, scarring, damaged testicles, kidneys, and blinded in one of their eyes (Wright). They sometimes lose confidence or hope in themselves (“What Effects”). Bullying can cause kids to have mental, physical, and social problems. Children that are bullied are more capab...
