Literature. A Mexican American girl Essay Example | Topics and Well Written Essays - 500 words

Literature. A Mexican American girl - Essay Example He was an example of an unreliable narrator, due to the many facets of his character. Montresor seemed to be lacking in friendships, sensitive, but devious and vindictive and most probably slightly paranoid. He perceived himself to be above or at any rate, alienated from the 'common herd', and believed he was a connoisseur of good wines. This last, he used as a trick to achieve vengeance on a supposed enemy. He appeared to be a complete loner through choice, and looked down on the rich who had not the old family heritage he possessed. He could be described equally as a sad, pitiful individual or a dangerous mad man. Esperanza would put a Want Ad. in the paper for a used portable typewriter. She knew she had talent; her aunt Lupe told her to keep writing. She valued education, working to pay for it, and admired Alicia for studying. A typewriter would be a good start for her dreams to be made real. He would put an obsequious obituary in the paper, as this would give him an opportunity to gloat over his success at achieving redress, while removing suspicion from himself. It would also allow him to appear to be mourning publicly and reinforce the faade of his and Fortunato's alleged friendship. He would use this as a way to state his superiority over others in his society. Her tone and style would be serious

Development and Diversification of Living Organisms Assignment

Development and Diversification of Living Organisms - Assignment Example The complete set of genes within a living organism’s cell is called genotype. On the other hand, the complete set of physical characteristics that make up the structure of an organism is called phenotype. The limitations of these factors will inhibit the reproduction process, which of course results differ from one species to another because of the differences in characteristics that are inherited and environmental influences. This variation is also the result of a process called mutation, which is caused by radiation, viruses, and errors during DNA replication. Genes that arise by mutation and found at the same place on a chromosome is known as an allele. Thus, it can be said that evolution is the result of two opposing forces. According to Hardy-Weinberg’s Theory, the genotype and allele frequencies of a population will often remain in equilibrium, unless disturbing influences, such as mutation, is present. The equilibrium state is only possible when the genotype and allele frequencies do not change. This happens when a population has a large size, which prevents the occurrence of genetic drift, bottlenecks and founder effects. The equilibrium state also occurs when there is no mutation, as explained earlier and that random mating takes place, which is explained below. However, this is hardly the case. In other words, if the equilibrium state is violated by factors such as those mentioned above, then evolution will take place. The genotype and allele frequencies are influenced by environmental and cultural events. A given genotype frequency can occur with random mating in a single generation as this causes the evolution of a given species, which in turn produces a new equilibrium within that one generation. For instance, continuous random mating of a black-haired population will result in homozygotes. Such violations include inbreeding, assortative mating, and small population size. On the other hand, a change in allele frequency can occur when selection, mutation, and migration happen.
