Europeans and Native American culture 2 - Essay Example It shall also focus on how the colonials governed themselves within the religious societies, which evolved constantly despite the restrictions, policies and laws of England and her parliament. Lastly, the paper shall conclude. The relationship between Europeans and Native Americans would be termed as interactive. Native Americans taught Europeans what to wear, how to grow food, and innovative forms of transportation. Native Americans implemented the technology of Europeans like weapons. Europeans brought horses into the land of natives, which they would use to move on the plains and hunt buffalo. The Europeans categorized the natives as superstitious savages thus converted them to Christianity1. Europeans altered the native language through teaching them English. Out of interaction connecting cultures, something novel came and peculiarly American. The new settlers brought diseases with them. A new reality would be seen, in which an ordinary cold made the natives ill, and others died. The entire villages in North America got wiped out by diseases like smallpox, cholera, measles and pneumonia. Smallpox proved to be extremely virulent. It spread extensively among the migratory tribes. The North Americans would be forced to reestablish themselves elsewhere. They suffered malnutrition and death eventually2. The climate fluctuations affected the grasslands’ productivity, native subsistence and migration patterns. There were food shortages that resulted to starvation. This facilitated and exacerbated the effects of diseases on populations and individuals. The colonies encompass the corporate, who got support from companies organized within England for profit. The proprietary involves those contracted as proprietorship to individuals. The crown gets controlled by the monarch. In religious matters, a board or committee known as council formulates laws for administration. The colonists were the secretaries of puritan. The first government of

Enviornmental Biotechnology - Research Paper Example The contamination of drinking water by these compounds is a major concern, and has led to the development of water treatment strategies aimed at their removal. The EDCs have been implicated in disorders of the neuroendocrine system, specifically on the hypothalamic neurotransmitter system, size of specific hypothalamic region, and the numbers of cells expressing the estrogen receptor ÃŽ ² . Certain chemical groups can disrupt and mimic reproductive hormones of fish, resulting in feminisation and premature egg yolk production in fish. Aside from effects on the reproductive system, these disrupters of hormonal activity have also been related to the prevalence of obesity and lately, schizophrenia. Cylindrospermopsin (CYN) is a freshwater algal toxin that is produced certain cyanobacterial species. The strains producing CYN are widely distributed in different regions of the world. These are Cylindrospermopsis raciborskii, Umezakia natans and Aphanizomenon ovalisporum. Cylindrospermopsin is a tricyclic alkaloid with a tricyclic guanidine moiety combined with hydroxymethyluracil. It is considered a globally important freshwater algal toxin. The tolerable daily limit for cylindrospermin is 0.02 g/kg body weight/day (2) . Ingestion of CYN can result in liver and kidney damage with bloody diarrhea and urine (2). Several methods have been developed for the detection of CYN (3). CYN has has a maximum UV absorbance at 262 nm, and an easily identifiable peak. The first screening method for CYN used reverse phase high performance liquid chromatography (HPLC) coupled with photo diode array detection.Later HLPC-mass spectrometry with electrospray increased the detection limit to 200 ÃŽ ¼g L-1. With tandem mass spectrometry, 1 Â µg of CYB can be detected. The techniques used earlier were quite expensive and the development of polymerase chain reaction amplification systems were developed so with
