Enviromental Science - Water Quality Parameters Movie Review

Enviromental Science - Water Quality Parameters - Movie Review Example However, group 3 found a turbidity value of 30 downstream and group 4 found a turbidity value of 40 upstream. Temperature – the temperature of the water in the stream is within the normal temperature range. Water is cooler upstream than downstream meaning that metabolism activities in the stream are in the normal range. Temperature also affects reproductive activities in the stream and life cycles in general. Dissolved oxygen – it is the mass of oxygen present in the water, and its units are parts per million (ppm) or milliliter per Liter. The average dissolved oxygen of 7ppm means that the mass of oxygen in the water is within the required range for aquatic life. The values of 5.6 ppm and 5.2 ppm for dissolved oxygen upstream and downstream respectively shows that oxygen levels are lower than average. The amount of dissolved oxygen may be affected by temperature, flow of water, aquatic plants and altitude. Percentage Saturation – the percentage saturation is 62.2% upstream and 59% down stream. This is an indication of high metabolic activities in the stream that result in the production of by-products that increase the saturation of salts in water. This is a key parameter that lowers the water quality in the stream. PH – the pH of water in the stream is extremely crucial. It affects the ecosystem and toxicity of the water. The average pH of water in a stream is 6 – 7. The pH of water in the stream is 8.05 upstream and 7.9 downstream. This pH levels are suitable for aquatic life in the stream. Phosphate (ppm) - phosphate is a limiting nutrient which means that it is in short supply compared to nitrogen. The stream has low phosphate values of 1.6 and 1.4 for upstream and downstream

Paper 2 - Essay Example Secondly, I support the civil rights movement, because its leaders including Martin Luther King Jr. acknowledged the importance of integrating the leadership of whites and that of blacks, among other minority groups (Taylor 156). Their view was opposed to the Black Nationalism’s goal of displacing and the revolting against the entre leadership system held by the white people. Through this letter, I will communicate the different reasons, and the critical areas that compelled me to decline the opportunity of working with the OAAU; instead, am in favor of the outlook of the civil rights movement. The first reason as to why I decline the invitation to work with OAAU is that all through the years between 1953 and 1965, despite the efforts of the members of the civil rights movement, the followers of Black Nationalism took an opposite trajectory (Reed 151-155). ... From the outlook that the entire array of Western culture phenomena was based on prejudice and hypocrisy was faulty, mainly because the integration of the black people into the mainstream society would offer them access to platforms for causing change. For example, at the time, very few black people had considerable education; therefore their chances of taking leadership positions were very minimal (Cone 134). The negative outlook of the Black Nationalist movement, which houses the OAAU, is evident from the decrees of Malcolm X, who held that the control of justice, taking center-stage in economics and separatism were the only options that would change the racist situation in the American society. However, Malcolm had little thought of the economic infrastructures that they would use to remain independent; many blacks were not educated to levels that would guarantee effective leadership and he did not regard whether separatism would affect the black society positively or negatively ( Cone 134). Second evidence that Malcolm X’s organization does not offer the better option to the problems facing the black people is that, he believed that violence was the only channel, through which social change could take place; he believed that nonviolence was the philosophy of the fool (Taylor 156). However, it is necessary to note that violence has not yielded positive effects in the past, further; using violence could affect minority groups like the blacks negatively. The third evidence is that the institution of ethical values, developing their own society and setting self-help groups was likely to alienate the black people, from the mainstream economy, noting that they were not the majority. The second
