Animals are all amazing, but some have a better defence than others. All prey animals need these defences to survive attacks from predators. And I am going to test these defences to see which is better. So who is it, the Armadillo or the Electric eel? Let's start out with the Armadillo. The Armadillo has three different species, the Six Band Armadillo, the Giant Armadillo, and the Three Band Armadillo. Despite most people's beliefs, the Three Band Armadillo is the ONLY Armadillo that can roll into a ball. But don’t worry the other Armadillos have a defence to, they jump at their attacker to startle it and then run away to the nearest shelter. Now onto the next competitor, the Electric eel. The Electric eel sends a jolt of electricity
Being who you are is easier said than done. We all have heard this lesson before, but it is much harder to actually do this in front of friends, and relatives. In “Fish Cheeks” by Amy Tan, and “Taco Head” by Viola Canales, both narrators face the struggle to fit in. They come from smaller cultures rather than the larger American culture. In the end, both girls learn a valuable lesson to be independent, and to be proud of who you are. In “Fish Cheeks” and “Taco Head” the similar lessons the narrators learn is, to be proud of who you are. However, the stories are different because in “Fish Cheeks” being American on the outside is okay, but you must remain Chinese on the inside. In “Taco Head” the lesson teaches that
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.
Facial scrapes, bruises, cuts and fractures are only few of the physical signs battered woman might suffer from. Public awareness increasingly rises over domestic violence. Domestic violence is an awful phenomenon that many women are suffering from. We can distinguish between two main types of abusive men. The two types are cobras and pit bulls. In this essay I will describe the similarities and differences between cobras and pit bulls.
The original use of electricity as a cure for “insanity” dates back to the beginning of the 16th century when electric fish were used to treat headaches. Electroconvulsive therapy on humans originates from research in the 1930’s into the effects of camphor-induced seizures in people with schizophrenia (Guttmacher, 1994). In 1938, two Italian researchers, Ugo Cerletti and Lucio Bini, were the first to use an electric current to induce a seizure in a delusional, hallucinating, schizophrenic man. The man fully recovered after eleven treatments. This led to a rapid spread of the use of ECT as a way to induce therapeutic convulsions in the mentally ill. Lothar Kalinowsky, Renato Almansi, and Victor Gonda are further responsible in spreading ECT from Italy to North America (Endler, 1988). Although there is some confusion as to who exactly is credited for administering the first ECT in America, it is known that it occurred in the early 1940.
Electronic controlled devices basically use high voltage, low wattage electrical charges to induce involuntary muscle contractions that cause a subject to be temporarily incapacitated. The weapon system is designed to fire two probes, or darts, that are attached to insulated wires. When the probes make contact with a person, the Taser will produce 50,000 volts of electricity, but only .0021 amps. According to Taser International, Inc. “it is not the volts that are dangerous it is the amps.” Volts are simply the rate the electricity is moving, but amps are the measure of current in the electricity.

In the 1880s, there was a war going on in the United States. Backstabbing, secrecy, and death were common. However, this war had no weapons. It was a dual between two geniuses. These two men are the fathers of modern technology. The War of Currents was a battle between the famous inventor Thomas Edison, and the mysterious genius Nikola Tesla. Tesla and Edison engaged in an epic competition to create the most efficient, cheap, usable form of electricity. Everyone knows who Thomas Edison was, but not many people know of Nikola Tesla. Tesla was an unappreciated mastermind who changed the world with his inventions, performed many strange experiments, and practically invented usable electricity.
could not get attacked by a Tyrannosaurus Rex. There is no way to tell how an animal
Leopard uses constant motion. It doesn’t stay in one spot for more than a blink of an eye. You use shifting body movements and footwork to evade and set up the next wave of strikes. The Leopard’s defense is a secondary by product. The Leopard does not commit itself to any one action. It can make a yummy treat for the Dragon. The Leopard’s reliance on multiple attacks and makes it vulnerable to the vital strike and grappling attributes of the Snake.
Even though there are so many differences between reptile species, there are a few things they all have in common. All reptiles are coldblooded, which is not quite right because there blood isn't cold. Coldblooded or poikilothermic actually means that the animals temperature must be regulated by external factors, that is why lizards are always sun bathing to get warm or in holes to cool off.
Medicine and electronics are rapidly becoming a common partnership. Electronics and medicine has been around for over a hundred years. This application can be seen in early X-ray machines, as well as early doctors and healers who felt that electricity possessed something special that assisted the healing process of many illnesses and injuries. But it has not been the last forty to fifty years that the development and refinement of electricity as medical agent has occurred. Today the medical field can not imagine itself without the assistance of electricity and electronic components.
In New York City during the late 1880’s, a fierce battle was raging between two great innovators of the age. The combatants, Thomas Edison and Nikola Tesla, were fighting over the prize to power cities in the ever more industrial world. Thomas Edison championed his direct-current (DC) system whereas Nikola Tesla was proposing his system using alternating-current (AC). This “War of the Currents” ushered in the electrical age, from which our modern society arose. Just as the AC and DC electrical generating systems where diametrically opposed to each other; so were Nikola Tesla and Thomas Edison.
Freshwater fish and saltwater fish are very similar in a lot of ways, but also have differences between them so you can tell them apart. Marine water (saltwater) equals over 96 percent of the water on Earth and over 70 percent of Earth’s total surface. Freshwater is less than four percent of Earth’s total water and is about one percent of Earth’s surface (Freshwater Fish). Interestingly a few species of fish can live in either freshwater or saltwater, but for the majority, they must live in a specific environment. All species of fish used to live in a saltwater environment until certain geological events (earthquakes, volcanic activity, etc.) occurred, creating conditions that isolated groups of fish. The new habitats, included freshwater, and new food sources caused fish to either adapt, or to die (Lohrey).
After researching so many things that I never even knew about reptiles, I believe I would much rather be a reptile instead of an amphibian. Reptiles were able to adapt to land while amphibians can barely even stay away from water for long periods of time. After all these years reptiles have evolved to modern day qualities and are still evolving to fit in. This paper is important to people who want to learn a little history about reptiles. It also tells what changes occurred in reptiles as they evolved.
Do you ever wonder about what happens with electricity? In the article “Energy Story” written it tells you about atoms and what things need to have to be that type of object. In the article “Conducting Solutions” by Rodney Schreiner tells you about solutions and the reactions to them with electricity. In the video clip “Hands-on Science with Squishy Circuits” by AnnMarie Thomas it tells you about how simple play dough can hold electricity.
There are two kinds of species of alligators. There is the American alligator and the Chinese alligator. Many people have a hard time telling the difference between alligators and crocodiles. Alligators are related in the same family as the crocodile, but these two animals are very different. An alligator’s upper jaw overlaps the lower jaw. Alligators have a broad snout while crocodile have a very narrow snout. Alligators have much less aggressive and energetic than the crocodiles. Alligators live in tropical climates and crocodiles live in somewhat colder climates. Their kingdom is Animalia. Their Phylum is Chordata. They come from the class Reptilia. Their order is Crocodylia. Their family is Alligatoridae. Their genus is Alligator and their species is alligator messissipiensis and they are known as American alligators.
