THE BUBONIC PLAGUE
THE BUBONIC PLAGUE
THE BUBONIC PLAGUE Rana Kundu Introduction Plague, was a term that was applied in the Middle Ages to all fatal epidemic diseases, but now it is only applied to an acute, infectious, contagious disease of rodents and humans, caused by a short, thin, gram-negative bacillus. In humans, plague occurs in three forms: bubonic plague, pneumonic plague, and septicemic plague. The best known form is the bubonic plague and it is named after buboes, or enlarged, inflamed lymph nodes, which are characterist
Volcanos
Volcanos
Volcanos Volcanos occur all over the world.The best know volcano zones occur on the destructive plate margin around the Pacific Ring of Fire.This chain of volcanos that lie along the west coast of central and south America,Japan and the Philippines,across New Zealand and into the Atlantic.Volcanos also occur in mid-ocean along the line of ocean ridges.The Mid-Atlantic Ridge is an example of ocean floor volcanos.When these volcanos erupt lava flows from the cracks building up the ocean floor.Volc
The Ebola Virus
The Ebola Virus
The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that are know to
Mammals
Mammals
Mammals There are three groups of mammals; egg-laying mammals ,pouched mammals and placental mammals. These three types of mammals are different for one main reason: reproductive methods. The egg-laying mammals lay eggs. The pouched mammals give birth to underdeveloped offspring. The offspring then spends time in the mother's pouch, and mature. The placental mammals keep their offspring inside them then give birth to a fully developed offspring. 2. The anteaters and spiny ant eaters were two sep
Dogs And Cats
Dogs And Cats
Dogs and Cats I am going to compare and contrast the similarities and differences between dogs and cats. The similarities are innumerable, yet this holds true with the differences as well. First, we shall discuss the similarities that these two creatures share. One of the most obvious similarities between these two animals is that they both have hair. When a creature has hair, it belongs to the mammal kingdom. This means that they give birth to their young. They also drink milk when they are bab
Bald Eagles And Golden Eagles
Bald Eagles And Golden Eagles
Bald Eagles and Golden Eagles Eagle is the common name for a number of diurnal birds of prey, some of which are the largest members of their family which also includes kites, hawks, buzzards, and certain vultures. The name eagle is somewhat loosely applied, as several of the groups are not particularly closely related to one another, and some birds called hawks are larger than some called eagles. The Bald Eagle (Haliaeetus Leucocephalus) and the Golden Eagle (Aquila Chrysaetos) are two eagles th
The Spectacled Bear
The Spectacled Bear
The Spectacled Bear The Spectacled Bear, or Tremarctos Ornatus, is an endangered species. This rare bear can only be found in a few elusive spots in the world. Many endangered species all over the world don?t deserve the respect and care that they need. That is why many endangered species often become extinct or remain on the endangered species list for the remainder of their survival on Earth. Today, as more species become endangered, more people become involved in their care. Many things are b

Brazil nuts reproduction ecological report Dr. Alan Rizzo IB Biology SL Y1 January 13, 2014 Brazil nuts reproduction ecological report Brazil nuts contain exceptional nutritious elements and can only be harvested in the Amazon forest of Brazil. Each Brazil nut tree towers high up to 200 feet; its branches provide habitat and food for other animals. Despite the fact in which only those Brazil nut trees that grow in undisturbed forests bear fruit, their reproduction has high dependency on other or
Animal Behavior
Animal Behavior
Animal Behavior Biology lb Abstract Animal behavior is predictable. Their behavioral tendencies are influenced by the relationship of its anatomy to their environment. By observing various forms of life, and associating the mechanism of their abilities to perform a behavioral action, evolutionary influence thereafter, can be analyzed and deduced from that point. Introduction The science and study of animal behavior involve an enormous array of complicated factors. For instance, stereotyped respo
