I need some assistance with these assignment. the mistaken extinction Thank you in advance for the help! The book mainly underlines the assumptions which the different scientists have proposed which have become different schools of thoughts relating to the mystery of the extinction. It also at some point questions whether or not the dinosaurs are actually extinct or they have evolved into some higher species which we see around us. Thus the book puts forward an even more interesting proposition claiming that the dinosaurs may still be present among us only in an evolved fashion which we are not able to understand on distinguishing by our naked eye.

In the beginning, the book tries to underline all the given facts that we actually know about the extinction of the dinosaurs. It states that although the cause of the extinction is not known most scientists are sure of the period in which the dinosaurs ceased to exist, which the Cretaceous period. The Cretaceous period marked about some three-quarter extinction of both the plant life and the animal life in the form of dinosaurs. In Earth’s geological record the Cretaceous period can be marked as the K-Pg boundary which is found in both marine and terrestrial rocks. The book tries to solve the entire case of this mystery extinction just on the premise of solving a murder mystery in the several chapters which form the part one of the books.

The book is proposed to have two individual goals by which it tries to solve the mystery of the extinction of the dinosaurs. Firstly, it tries to distinguish the different hypotheses which are presented by different scientists during the different ages on the basis of scientific reasons. If scientific reasons are found for the hypothesis then the book has accepted them and carried forward in trying to analyze and establish them.&nbsp.

I will pay for the following article The Devastating Effects of Pesticides on the Environment. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. Once the pesticides are released into the environment, there is no telling what kinds of organisms will get affected. Moreover, because all of life in ecologies depend on one another, the decimation of some organisms because of toxicity to pesticides, such as non-target water organisms and insects, the damage to the whole ecology is profound, with other organisms along the food chain also being put at risk for death. As an example, some chemicals such as chlorpyrifos, common ingredients in many kinds of pesticides in agriculture, have been found to be severely toxic to all kinds of fishes, in both warm and cold glasses of water, causing such harmful effects as deformities in the vertebral parts of the fishes. Chemicals in Roundup, a chemical herbicide used in conjunction with GMO crops, have been found to likewise have a profound toxic effect on all kinds of water life, including fishes, with the impact including impairment in the ability of fishes to survive and to perform basic functions of being, including impairment in swimming and breathing so that the fishes contaminated with the pesticide ingredients become more likely to succumb to the actions of predators. This impairment inability to survive to threaten the ecology by subverting the natural ecological balance, with devastating effects on the whole ecology. Some species of aquatic animals, such as freshwater dolphins, have been put at risk of becoming extinct because of pervasive chemical pollution of water systems from commercial agriculture.&nbsp.In water systems that have been highly contaminated by toxic chemicals from pesticides, such as PCBs and DDTs the survival capabilities of other aquatic animals such as minks, otters and other fishes have become severely compromised, and the toxicity levels of such animals are predicted to rise with no pause due to the persistent and heavy use of pesticides and their subsequent leaking into the water systems. This is true for instance in India and the Ganges River, where the levels of chemical pollution from runoff feeding into the river have been shown to be chronically persistent (Aktar et al., 2009).&nbsp.

I will pay for the following article Codes of Cultural Behavior. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. I have chosen Tanzania because I once read the Bibliography of Tanzanian first president, Mwalim Julius Nyerere, and I really loved his socialistic ideals. This has made me to develop a lot of interest in Tanzania and I have always hoped to visit Tanzania one day in my lifetime. This is the main reason why I have chosen to research and to write on the Tanzanian codes of cultural behaviour.

Tanzania is made up of two states, i.e. Tanganyika and Zanzibar. Tanganyika became independent in 1961, while Zanzibar became independent in 1963. In 1964, Tanganyika and Tanzania signed an act of union to form the United Republic of Tanzania (Culture of Tanzania- history, people, clothing, traditions and religion).

On religion, the two predominant religions in Tanzania are Christianity and the Muslim. Muslim religion is predominant in Zanzibar, while Christianity is predominant in the mainland Tanzania. Besides the Christianity and the Muslim religions, there are also traditional religions in Tanzania, although, currently there number is insignificant. In Tanzania there are also other religions like the Buddhist and the Hinduism, although they account for a very small percentage of the population.

Linguistically, the national language of Tanzania is Swahili. But there are two official languages in Tanzania, i.e. Swahili and English languages. But besides the two official languages, there are 120 ethnic languages in Tanzania, corresponding to the 120 ethnic groups in Tanzania. But Swahili is spoken by everybody in Tanzania, and some of the ethnic languages in Tanzania are at the brink of extinction as people switch to the Swahili language (Culture of Tanzania- history, people, clothing, traditions and religion).

On ethnic composition, Tanzania has 120 ethnic groups, as we have just seen. This in essence means that there are 120 sub-cultures in Tanzania. There is, however, a distinct national Tanzanian culture that every Tanzanian identifies with. The national Tanzanian culture, however, is a derivative of the sub-cultures of Tanzania.

I will pay for the following article Economic Development and Environmental Protection. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. The deforestation of certain regions of the world is certainly compounding the pollution problem since this deforestation and rise in pollution levels often takes place in countries that have precious few remaining options for economic growth (Hertsgaard, 1997). For example, forests in India are being cut away to make room for growing cities and farmland for villages. The Gir forest is one example of a region which is being cut away to make the land available to mango farms and quarries for limestone. Millions of hectares in forest land are destroyed annually around the world of which the majority takes place in locations like South America (Mabogunje, 2002).

At the same time, the pollution levels of cities and industrial zones in South America are approaching a critical level as more than ninety-five percent of the forest land in Brazil and Costa Rica is gone. In the Philippines, 90% of the land covered with forests is now being used for other purposes. If this situation is allowed to continue unchecked, within a few years, there would be no forests left in developing countries except in zones which are dedicated to habitat protection and forest preservation where armed guards protect the trees (Rich, 1994).

Undoubtedly, it is human activity and human growth which is causing pressure on the ecological systems of the planet. These activities take place at a very high rate in nations like India and China which are seeking to make their mark in terms of economic development and progress. While they seek development, they also utilize fossil fuels and whenever these are used to drive cars, provide power to offices or run the wheels of industry, significant pollution is added to the ecological system (Hertsgaard, 1997). While a certain amount of pollution can be handled by nature, excess pollutants and greenhouse gasses such as carbon dioxide and other chemicals upset the delicate ecological balance. The present rate of pollution in these developing countries also means that their cities have become some of the worst offenders in terms of pollution.

Need help with my writing homework on Trends on Healthy Eating: Americans’ Eating Habits. Write a 1250 word paper answering; One reason driving the shift could be greater public awareness and pressure on those who manufacture foodstuff and even on restaurants to produce healthier foods. Another reason could be because of a change in lifestyle habits (Beck and Schatz 2). Consumers nowadays are tracking calories and nutrients they consume using their Smartphone’s applications, and these apps can help them choose healthy food say at restaurants, according to Susan Ryskamp, a nutritionist at the University of Michigan Medical Center in Ann Arbor (qtd in Beck and Schatz 1). Moreover, a number of meals people eat in restaurants have gone down, according to NPD, a market research firm (qtd in Beck and Schatz 1).

Government policy could also be contributing to change in the trend of healthy eating. The Affordable Care Act requires restaurants and food manufacturing firms to provide more information about the food to help people make better decisions in encouraging this shift (Beck and Schatz 2). Some restaurants now print calorie values on their menus, which helps customers make informed decisions. Recent actions by the government also seem to contribute to the shifting trend of healthy eating (Beck and Schatz 2). Recently, the U.S. Department of Agriculture (USDA) has been giving advice to grandparents on how they can encourage their grandchildren to eat healthier food. This is definitely contributing to the shift to healthy food eating (Beck and Schatz 2).
