Biology Instinct Essays - Animal Anatomy, Zoology, Entomology Biology Instinct subject = biology title = Biology Instinct Insects are neumerout invertebrate animals that belong in the Phylum Arthropoda and Class Insecta. The class Insecta is divided into 2 subclasses: Apterygota, or wingless insects, and Pterygota, or winged insects. Subclass Pterygota is futher divided on basis of metamorphosis. Insects that have undergone incomplete metamorphosis are the Exopterygota. Insects that undergo complete metamorphosis are the Endopterygota. Insects have an outer bilateral exoskeleton to which the muscles are attached to and provides protection for internal organs. The body is divided into 3 main parts which are the head, which include mouthparts, eyes, and antennae; thorax, which operate the jointed legs and /or wings; and abdomen, which has organs for digested food, reproducing, and getting rid of waste products. The major systems in insects are the circulatory, respiratory, nervous, muscular, digestive, and reproductive systems. In the circulatory system, blood is pumped by the heart in a tube to the aorta, the head, and to other organs then enters the ostia openings along the sides of the tube back to the heart. The respiratory systems carries O2 to cells and takes away CO2 from cells through branching out to call cells of body. The nervous system consists of a brain receiving information from eyes, antennae, and controls the whole body and 2 nerve cords containing ganglia fused together to control activities of the segment without the help of the brain. insect muscular system is made up of a few thousand samll but string muscles allowing the insect to carry objects heavier than it. The digestive system is basically a long tube where food enters the mouth to the crop where it is stored, gizzard where it is grinded, stomach where it is digested, then the undigested parts and wastes are moved to the intestine, colon then released at the anus. And in the reproductive system, a new individual is produced sexually when the female eggs produced in the ovaries united with male sperm produced in the testes. Both man and insect live almost everywhere, eat all kinds of food, and use all kinds of materials to build homes so they constantly live in conflict. Some insects seriously affect man's health and are parasitic on man and other animals. insects that feed on human or animal blood can carry disease in their salivary juices and spread the disease to other animals. Many insects irritate us without disturbing our health. Some bite and sting, and some people are allergic to them and some insects are injurious to our agricultural crops, food products, clothing, and wooden buildings. So far man has only partial success in defending against insects. But some insects species are beneficial to man. The honey bee, for example, supplies us with honey and the silkworm supplies us with silk. So bugs really aren't that bad.

Red Army Faction or Baader-Meinhof Group

Red Army Faction or Baader-Meinhof Group The left-wing terrorist group Red Army Factions main objective was to protest what they perceived as fascist-leaning and otherwise oppressive, middle class, bourgeois values of West Germany. This general orientation was coupled with specific protests of the Vietnam War. The group pledged allegiance to communist ideals and opposed the capitalist status quo. The group explained its intentions in the RAFs first communique on June 5, 1970, and in subsequent communiques in the early 1970s. The group was founded in 1970 and disbanded in 1998. According to scholar Karen Bauer: The group declared that ... its aim was to escalate the conflict between the state and its opposition, between those who exploited the Third World and those who did not profit from Persian oil, Bolivian bananas and South African gold. ... Let the class struggle unfold! Let the proletariat organize! Let the armed resistance begin!(Introduction, Everybody Talks about the Weather...We Dont, 2008.) Notable Attacks April 2, 1968: Bombs set off by Baader and three others in two Frankfurt department stores cause significant property destruction. At trial, Gudrun Ensslin, Baaders girlfriend and a committed activist, claimed the bombs were intended to protest the Vietnam WarMay 11, 1971: A bombing of US barracks killed one US officer and wounded 13 others.May 1972: Bombing of police headquarters in Augsburg and Munich1977: A series of killings designed to pressure the German government to release detained members of the Group take place, including the assassination of chief public prosecutor Siegfried Buback; the assassination of Dresdner bank; Hans Martin Schleyer, abduction of the head of the Germany Association of Employers and former Nazi party member.1986: Siemens executive Karl-Heinz Beckurts is killed. Leadership and Organization The Red Army Faction is often referred to by the names of two of its primary activists, Andreas Baader and Ulrike Meinhof. Baader, born in 1943, spent his late teens and early twenties as a combination of a juvenile delinquent and stylish bad boy. His first serious girlfriend gave him lessons in Marxist theory and later provided the RAF its theoretical underpinnings. Baader was incarcerated for his role in setting fire to two department stores in 1968, briefly released in 1969 and re-imprisoned in 1970. He met Ulrike Meinhof, a journalist, while in prison. She was to help him collaborate on a book, but went further and helped him escape in 1970. Baader and other founding members of the group were re-imprisoned in 1972, and activities were assumed by sympathizers with the groups imprisoned founders. The group was never larger than 60 people. The RAF After 1972 In 1972, the groups leaders were all arrested and sentenced to life in prison. From this point on until 1978, the actions that the group took were all aimed at gaining leverage to have the leadership released, or protesting their imprisonment. In 1976, Meinhof hung herself in prison. In 1977, three of the original founders of the group, Baader, Ensslin, and Raspe, were all found dead in prison, apparently by suicide. In 1982, the group was reorganized on the basis of a strategy paper called, Guerrilla, Resistance, and anti-Imperialist Front. According to Hans Josef Horchem, a former West German intelligence official, this paper †¦clearly showed the RAFs new organization. Its centre appeared at first still to be, as hitherto, the circle of RAF prisoners. Operations were to be carried out by the commandos, command level units. Backing Affiliation The Baader Meinhof Group maintained links with a number of organizations with similar goals in the late 1970s. These included the Palestine Liberation Organization, which trained group members to use Kalashnikov rifles, at a training camp in Germany. The RAF also had a relationship with the Popular Front for the Liberation of Palestine, which was housed in Lebanon. The group had no affiliation with the American black panthers but announced their allegiance to the group. Origins The groups founding moment was in a demonstration in 1967 to protest the elitism of the Iranian Shah (king), who was visiting. The diplomatic visit drew large grounds of Iranian supporters, who were living in Germany, as well as opposition. The killing by German police of a young man at the demonstration spawned the June 2 movement, a leftist organization that pledged to respond to what it perceived as the actions of a fascist state. More generally, the Red Army Faction grew out of specific German political circumstances and out of broad leftist tendencies in and beyond Europe in the late 1960s and 1970s. In the early 1960s, the legacy of the Third Reich, and Nazi totalitarianism was still fresh in Germany. This legacy helped shape the revolutionary tendencies of the next generation. According to the BBC, at the height of its popularity, around a quarter of young West Germans expressed some sympathy for the group. Many condemned their tactics, but understood their disgust with the new order, particularly one where former Nazis enjoyed prominent roles.
