Environmental science Please answer it ASAP 1. Why do water managers care about turbidity? How do water managers estimate the bacterial disease risk associated with drinking water? 3. What is eutrophication? 4. In a stratified lake (has fayers), which layer has the best drinking water? Bonus: What facility is the largest nonmilitary user of explosives in the world? It is located in Florida. Solution Q1).The measurement of turbidity is a key test ofwater quality. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom of the container if a liquid sample is left to stand (the settable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles arecolloidal. These small solid particles cause the liquid to appear turbid. Q2.Water, the environment and people’s health • Part 4 53 MANAGEMENT ISSUES FOR DOMESTIC WATER SUPPLY. What factors are important in the management of the microbial quality of domestic water supplies? The important factors are (i) disinfected drinking water, (ii) sound disposal of faecal wastes, (iii) application of good personal, food and water use hygiene, (iv) use only of safe water for crops eaten raw. In the management of water quality for domestic purposes it is important to bear in mind that the achievement of the goal of providing safe water for drinking and food preparation rests on the management of the safety of the water supply along the whole supply chain. The water supply chain consists of the water source, treatment works, distribution system, the supply tap, the drinking water container, jug or cup. (See vol., 5, Management Guide, DWAF, DOH & WRC, 2002). Dirt that has gained access to the water supply line or tank (e.g. high-rise buildings) often causes problems in the management of water for domestic purposes, • In the case of the repair of a burst pipe where dirt may gain access to the supply line, this may cause a temporary elevation of the microbiological total plate count in the supply line, but the consumer is usually alerted to the problem by brown water coming out of the tap. The situation is usually remedied by flushing the tap and allowing the plug of contaminated water to flow down the drain. • Rodents may gain access to gravity feed tanks on top of high-rise buildings which may not be covered properly. This typically results in foul smelling and tasting water, and the consumer is alerted to the problem. Such tanks will need flushing and proper screening of any access points. The other situation which needs attention is to ensure that containers that are used in the home for storing drinking water are clean and that they are properly covered to ensure that flies and dirt do not settle into the water in the container. One of the quickest ways to contaminate water in a bucket, for example, is to dip an unwas.

Discuss a specific public health concern for each of the following groups: a. Americans of Hispanic Origin b. African Americans c. Asian Americans d. Pacific Islanders e. American Indians & Alaskan Natives Solution a). The prevalence of diabetes is found to be different in different groups of people. In United states, the prevalence is more in case of Hispanic Americans that that of the White Americans or black population. Also, African Americans have higher incidence than the white Americans. b). African Americans are at higher risk of developing heart diseases than any other population, about 3/4th of the population develop high blood pressure after 40 years of age. Their health access is very less and do not visit a physician for regular checkup. Means they are less likely to take any preventive medicines, which increases the risk of developing high blood pressure and lethal heart problems. c). As per the health statistics, Asian Americans are less prone to diabetes and hypertension. d). Pacific Islanders are at higher risk of developing type 1 diabetes..

Due to your interference with organisms on the planet, one species of flying insectivorous organism that formerly lived near Lake Agassiz on Wallace have moved to a location just south of Lake Lyell. Unfortunately, there is already a different species of flying insectivorous organism very similar to the first organism living near Lake Lyell. Describe in detail what things (multiple things)might happen as these two species interact. and what methods they can adopt to avoid extinction with example. Solution The migration of flying insectivorous organism from Lake Agassiz on Wallace to Lake Lyell. This leads to a competition between two organisms for their sustainability. Interspecific competition could be observed between these two species. The interspecific competition if it is drastic might lead to complete change in the population size of unfitted organism through natural selection. The species which has been gets suppressed due to over - aggressive species gets completely excluded or the unfitted species gets change itself its natural characteristics if it is competent. The adaptations such as flexibility of the newer species to change itself to newer climatic conditions, acclimatization and learning helpful for the survival of a new species which gets migrated to a newer habitat..

ANS: A. Epidermis Location: outermost layer of the skin Tissues: Epithelial tissue Characteristics: It is a protective waterproof barrier that also keeps pathogens at bay and regulates body temperature B. Dermis: Location: Middle layer present in beneath the epidermis of the skin Tissues: Connective tissue Characteristics: It is a thick layer of fibrous and elastic tissue (made mostly of collagen, elastin, and fibrillin) that gives the skin its flexibility and strength. C. Hypo dermis: Location: Deeper subcutaneous tissue layer of the skin Tissues: Fat and connective tissue Characteristics: It maintains the body temperature. 2. ANS: Stratum corneum and stratum basale difference: The cells of stratum basale are cuboidal to columnar and the stratum corneum cells are made with keratin. 3. ANS: In the location of stratum basale, melanin content specifically observed in dark (heavily pigmented) skin. 4. ANS: The dorsal side (posterior) of the forearm is the \"top\" side-- the side that usually faces upward and is generally darker than anterioir side. It is mainly due to melanin and hair follicles. 5. ANS: The special qualities of dermis connective tissue can contains with Collagenous fibers, elastic fibers, and a gel-like substance. 6. ANS: The sole of feet and the palms of hands are structured to perform day to day functions. The hardness on the skin on these locations is due to the layers of epidermis that contain dead keratinocytes are the Stratum corneum and stratum lucidum Stratum lucidum: Thin, clear layer present in the thick skin of the palms and soles; no remaining living cells. Stratum corneum: Several layers of keratinized corneum; a collagenous matrix composed of the products of dead cells. Keratin and the thickened plasma membrane protect the skin against abrasion and penetration, and the glycolipid between its cells nearly waterproofs this layer..

1a. What kinds of deductions are prohibited as a matter of public policy? bribes, kickbacks, and \"other\" illegal payments as nondeductibleT. 1b.Why might Congress deem it important to disallow deductions for expenditures against public policy? Solution The IRC lists bribes, kickbacks, and \"other\" illegal payments as nondeductibleCongress didn\'t want the tax benefits associated with deductions to benefit or subsidize wrongdoing of course, this rationale doesn\'t really explain the prohibition against deducting political contributions which is probably better explained by the potential perception that political efforts are being subsidized by taxpayers..

What is meant by cultural emergent and how does this differ from other approaches to culture? Explain how culture can be both persistent and ever-changing. Solution Cultural emergent and how does this differ from other approaches to culture discussion of the scope and limitations of current diagnostic practice criticisms from different quarters and the role and relevance of culture in the diagnostic encounter precede the examination of advantages and disadvantages of the approach the practical aspects include the acceptance of cultural discordances as a component of an updated definition of mental disorder and the use of a refurbished cultural formulation. This is why the recognition of cultural diversity can help to ensure that ownership of development and peace initiatives is vested in the populations concerned the message of sustainable development is that the planet is essentially finite and that the resources humanity hoped to discover in its environment must now be found within itself in its very diversity cultural diversity invites us to think in terms of a plural humanity embodying a creative potential that precludes any prescribed model of development. The acknowledgement of cultural diversity and intercultural dialogue help to defuse the tensions that can arise in multicultural societies when a majority and minorities confront each other over recognition of their rights although outcome research is limited culturally responsive behavioral health counseling results in greater counselor credibility. An archaeological eye to an examination of human response to unpredictable environmental conditions informed by an understanding of contemporary traditional peoples sustainable Lifeways enhances our understanding of both the forces of conservatism and innovation which may have been in play in major transitions in the past..

What is the role of Rb in the cell cycle and what types of mutations in Rb will be oncogenic? Explain your answer. Solution Cell cycle regulation by Rb: Gradual phosphorylation of Rb proteins causes their functional inactivation, which is regulated by cyclin dependent kinases. Rb proteins regulate the cell cycle in association with different transcription factors and chromatin-associated complexes. The transcription ability of E2F factors is inhibited by the binding of Rb proteins as they mask the transcriptional activation domain or convert them into transcription repressors. The two possible pathways through which Rb proteins mediate the inhibition of E2F regulated genes is, by direct binding to the activation domain and blocking it. The other one is, by repression through the HDAC , SWI/SNF factors or methyl transferases. As the retinoblastoma (Rb) is a tumour suppressor gene, so a loss of function mutation turns it to become oncogenic..
