Genetics - Lab Report Example Therefore, during the meiosis, four meiotic sexual haploid cells with altered heredity are produced and then genetic information is mixed. The second meiotic division is the same as mitosis one. As in mitosis, in meiotic anaphase II the single sister chromosomes (called chromatids) separate and move to opposite poles of the cell1. Meiosis is the basis of sexual reproduction because it occurs in maturing germ cells and leads to the appearing of new hereditary characteristics in the chromosomes. Gene is the coding DNA sequence that placed in the specific locus on the chromosome. Such coded chains displayed in different traits, such as color of skin or length of the stem. Allele is a variant of gene and can be dominant or recessive. For example, in diploid organism one gene contains two alleles; therefore, traits can be different. If both alleles are identical, the gene locus is homogenous. When alleles are different, such gene locus called heterogenic. A good example is the Huntington disease. Huntingtons disease has the autosomal dominant inheritance. Consequently, an affected person has at least one mutant allele of Huntingtin gene (HTT)2. The child, whose one parent is homogenous by disease, carries two different alleles of the HTT gene and is heterogenic by this gene. Therefore, this child inherited a mutant allele of HTT gene and the Huntingtons disease will progress. Another example is blood groups. Gene locus that encoded blood groups has three alleles — IA, IB, and IO3. These alleles determine compatibility of blood transfusions. The person carries one of the six possible genotypes – AA, AB, BB, AO, BO and OO. Each of genotypes produce one of the four possible phenotypes: "AB" heterozygotes, and "O" homozygotes, "A" AA homozygous and AO heterozygous and "B" BB homozygous and BO heterozygous genotypes4. Crossing-over is the process that occurs in prophase I of meiosis while homologous chromosomes

The death of woman Wang Essay Example | Topics and Well Written Essays - 1000 words

The death of woman Wang - Essay Example There were also published texts in 1673, 1763, and 1810 on the local history of the county (Cass and Spence 550). Additionally, Spence utilizes P’u Sung-ling’s text entitled â€Å"Strange Stories from the Liao Studio† in creative and unconventional ways. The data are all used to depict common superstitions and values and to draw the picture of â€Å"loneliness, sensuality, and dreams† (Spence xiv). The first part, â€Å"The Observers,† talks about the catastrophes that struck the region, focusing on the earthquake in 1668 that wiped out a big part of the population. Additionally, people were stricken with the White Lotus revolt in 1622, plagues in 1640, Machu invasion in 1643, coupled with famine, floods, and raids in the 1650s. In a matter of fifty years, the region’s population of 200,000 dropped to merely 60,000. It is obvious here that the T’an-ch’eng people faced survival crisis, misery, and demoralization during that perio d. Suicide was so common that a proclamation has to be issued to dissuade it. In Huang’s text, he mentions that when he was serving in T’an-ch’eng, he observed that people view themselves worthless due to the poverty, hunger, and several other sufferings they go through. He added that people then do not have any idea of a happy life and the joys of living (Spence 14). The moral situation of the people hit an all-time low, causing conflicts to erupt within the family units, breaking down of social orders, and abandonment of moral restraints (Cass and Spence 551).... The second part, â€Å"The Land,† explores the situation of the tax payments, quotas, and labor system. As the population fell, these established systems became more burdensome for the people, particularly the quota system. Registered lands dropped, showing the abuses in tax collections and the measures used by land owners to avoid paying the exorbitant taxes. Obviously, the established system in the land pushes the poor people more into poverty, giving them lesser and lesser hope --- which was not much to start with --- to be alleviated from their circumstances (Entenmann and Spence 269-70). The third part, â€Å"The Widow,† begins to explore the situation of the women in that region during that time. Historically, China’s view on women has been that of oppression, and they are merely treated with respect if they follow the conventional societal rules on the roles of women in the society (Cass and Spence 550). Spence here describes the burdens placed on widows, particularly by the legal code discouraging remarriage after the husband’s death. Remarriage would cause the widow to lose any inheritance from the husband to the husband’s family. However, instead of achieving the desired effect of proving the wife’s loyalty to the late husband, it merely prompted the husband’s family to put pressure on the widow to remarry. Spence however relates the story of a woman who resisted this pressure, which unfortunately resulted in the murder of her only son by her late husband’s family. The murdered was punished, but a part of the late husband’s family became the widow’s heir (Entenmann and Spence 270). In the fourth part, â€Å"The Feud,† Spence talks about a local family who runs a group of

Childhood and Depression Research Paper Example | Topics and Well Written Essays - 1000 words

Childhood and Depression - Research Paper Example Researchers propose that although major depression affects anywhere from three to five percent of children and adolescents, up to 15 percent of children and adolescents at any given time manifest at least some symptoms of depression (Bhatia and Bhatia 73). Despite the prevalence of depression in younger populations, there are a number of treatment avenues that parents and guardians can follow in order to alleviate an individual’s suffering in those areas of life most affected by depression. In order to prevent future generations from being severely and negative impacted by depression starting in the childhood or adolescent years, professionals and parents should be better educated to recognize the risk factors and the symptoms. Childhood depression, particularly in children younger than seven years, is particularly difficult because of children’s inability to give details about their internal mood states. However, symptoms like chronic irritableness, impaired attention, and poor concentration are common possible indicators of a depressed child. When diagnosing depression in children, doctors must rule out physical causes of such symptoms, such as chronic disease and vitamin deficiency. If the depression is the result of these physical causes, the depression is considered secondary to its medical prerequisite. Major depressive disorder is a primary diagnosis that relies on symptoms similar to those seen in adult depression. If the depression is not a major disorder, it could either be classified as adjustment disorder, which starts within three months of an identifiable stressor (such as the loss of a parent), or as dysthymic disorder, which is a milder form of depression characterized by irritable or depressed moods and must occur for no less than a year (Bhatia and Bhatia 75). The risk factors for depression are not equivalent to causes, since none of them alone leads directly and invariably to childhood depression. Some common risk factors for c hildhood and adolescent depression include psychosocial and biomedical factors; that is, nearly two thirds of children and adolescents who have major depressive disorder are comorbid with another severe or moderate mental disorder (Angold, Costello and Erkanli 76). That means that even if a child or adolescent has been diagnosed for one mental disorder, there should still be a concern that the patient has a related but separate mental disposition toward major or moderate depression. For physicians, they must be able to recognize and treat the associated physical sources of depression; the most common among them are dysthymic disorder, anxiety disorders, and attention-deficit/hyperactivity disorder. For parents, they must be able to identify and seek treatment for their child’s symptoms as soon as they recognize them. In terms of treatments, medication is a common avenue for physicians to take in order to alleviate their patients’ suffering because of depression symptom s. Tricyclic anti-depressants are largely ineffective in children and adolescents according to meta-analyses and SSRIs likewise have underwhelming effects on reduction of symptoms in children (Bhatia and Bhatia 78). Concerns about effectiveness and safety keep some parents from putting their children on these medications (Merrell 209). Currently, only fluoxetine is approved by the FDA to treat childhood depression, so it is acceptable in cases of major depressive

In 1549, the first governor general of Brazil was Tome de Sousa. During his period as governor general, there was an increase in evangelism in Brazil. Pedro Cabral explores the coast of Brazil under the orders from the King of Portugal (Beidelman, 73). The Portuguese signed the Treaty of Tordesillas that meant there was a division between Christians and non-Christians outside of Europe. The Jesuit missionaries spread Christianity to Brazil Indians. The missionaries clash with adventurers in Brazil with the main aim of capturing Indian and looking for minerals. The Jesuit missionaries play an important role in the spread of evangelism in Brazil and its surrounding areas (Rivera, PagaÃŒ n & Justo, 54).

The developed of skills to travel in the ocean meant that they could travel around the world in search of colonies. The discovery of ocean skills the world the Portuguese China trade between the 1514 and 1550 (Rivera, PagaÃŒ n & Justo, 54). Jorge Alvares was the first European Explorer to reach Asia. His arrival in China boosted trade within the region.

Econ ON OLIGOPOLY & SOME GAME THEORY IDEAS WITH OLIGOPOLY Assignment

Econ ON OLIGOPOLY & SOME GAME THEORY IDEAS WITH OLIGOPOLY - Assignment Example In the contestable market the evaluation of dealings among current firms and prospective entrants is investigated more critically. The market incumbents maintain an oligopoly through the determination of price levels in the market in their favor. Again the oligopoly is maintained by the government favor and creates a barrier for other firms from venturing in the market. 2) Suppose there are two firms operating in an oligopoly (termed a â€Å"duopoly†), where the firm 1 cost function is given by C1 = 18Q1, for C1 = total cost, and Q1 = firm 1 output. The cost function for firm 2 is given by C2 = 21Q2, and C2 = total cost of firm 2, and Q2 = output of firm 2. The inverse demand for the product, Q, being sold by the oligopolist firms is given by P = 127 – 3Q, where Q = Q1+ Q2, and Q1 and Q2 are the same product (vats of toxic solution for breaking down chemical components to be used in downstream plastic manufacture). Taking into the consideration the Cournot model in regard to the duopoly that is two firms where both firms concurrently decide a quantity to produce. Designating the quantity q1 as the amount produced by firm 1 and q2 as the corresponding amount produced by firm 2. Therefore the total quantity The firm production choices are strategic substitutes. That is, an increase in the amount produced by firm1 (holding fixed the underlying amount produced by the corresponding firm 2) will considerably lower the market price and thus resulting in lesser profits for firm 2. Thus, every firm ought to take into consideration the prevailing the production decisions of the other supplementary firm in the process of undertaking its individual production decision Firm 1 possess a marginal cost of production equivalent to c1 accompanied by firm 2 which possess a marginal cost of production equivalent to c2. The corresponding Nash equilibrium is computed through the employment tow
