美国芝加哥大学历史学Assignment代写:伊拉克战争

萨达姆侯赛因在1979年至2003年期间领导了一个残酷的伊拉克独裁统治。1990年,他侵略并占领了科威特国六个月,直到被国际联盟驱逐。在接下来的几年中,侯赛因对战争结束时达成的国际条件表示了不同程度的蔑视,即在该国大部分地区实行“禁飞区”,怀疑军火网站的国际检查和制裁。 2003年,美国领导的联盟入侵伊拉克并推翻了侯赛因政府。 建立联盟:布什总统为入侵伊拉克提出了一些理由。其中包括:违反联合国安理会决议,侯赛因对其人民犯下的暴行,以及制造对美国和世界构成直接威胁的大规模毁灭性武器(大规模杀伤性武器)。美国声称拥有证明存在大规模杀伤性武器的情报,并要求联合国安理会授权进行袭击。理事会没有。相反,美国和英国将29个其他国家列入“愿意联盟”,以支持和实施2003年3月发起的入侵。 美国芝加哥大学历史学Assignment代写:伊拉克战争 Saddam Hussein led a brutal dictatorship of Iraq from 1979 to 2003. In 1990, he invaded and occupied the nation of Kuwait for six months until being expelled by an international coalition. For the next several years Hussein showed varying degrees of contempt for the international terms agreed to at the end of the war, namely a "no-fly zone" over much of the country, international inspections of suspected arms sites, and sanctions. In 2003, an American-led coalition invaded Iraq and overthrew the Hussein government. Building the Coalition:President Bush put forward a number of rationales for invading Iraq. These included: violations of U.N. Security Council resolutions, atrocities committed by Hussein against his people, and the manufacture of weapons of mass destruction (WMD) which posed an immediate threat to the U.S. and the world. The U.S. claimed to have intelligence which proved the existence of the WMD and asked the U.N. Security Council to authorize an attack. The council did not. Instead,...

新西兰坎特伯雷大学教育学Assignment代写:终身收益随着教育而上涨

How much more is higher education worth in cold hard money than a high school diploma? Plenty.A college master's degree is worth an average of $1.3 million more in lifetime earnings than a high school diploma, according to a recent report from the U.S. Census Bureau.The report titled "The Big Payoff: Educational Attainment and Synthetic Estimates of Work-Life Earnings" (.pdf) reveals that over an adult's working life, high school graduates can expect, on average, to earn $1.2 million, while those with a bachelor's degree will earn, $2.1 million; and people with a master's degree will earn $2.5 million."The large differences in average work-life earnings among the educational levels reflect both differential starting salaries and also disparate earnings trajectories," noted the Census Bureau, "that is, the path of earnings over one’s life." Persons with doctoral degrees earn an average of $3.4 million during their working life, while those with professional degrees, like medicine, law, and engineering do best at $4.4 million."At...

新西兰奥克兰大学植物学代写:蕨类植物周期

从我们认识到的“蕨类植物”(孢子体)开始,生命周期遵循以下步骤:二倍体孢子体通过减数分裂产生单倍体孢子,该过程在动物和开花植物中产生卵子和精子。每个孢子通过有丝分裂生长成光合原叶体(配子体)。由于有丝分裂维持染色体的数量,原叶中的每个细胞都是单倍体。这种苗比孢子体蕨小得多。每个原hall通过有丝分裂产生配子。减数分裂不需要,因为细胞已经是单倍体。通常,原叶体在同一植株上产生精子和卵子。虽然孢子体由叶状体和根状茎组成,但配子体具有小叶和根状茎。在配子体内,精子在一个叫做天蛾的结构内产生。这种鸡蛋是在一种类似的结构中产生的,称为一种颈椎。当水存在时,精子利用鞭毛游向卵子并使其受精。受精卵仍然附着于原叶。卵子是由卵子和精子DNA合成而成的二倍体合子。合子通过有丝分裂进入二倍体孢子体,完成生命周期。在科学家了解遗传学之前,蕨类植物的繁殖是神秘的。它看起来好像成年蕨类从孢子出现。从某种意义上说,这是事实,但从孢子中出现的小苗与成年蕨在遗传上是不同的。请注意,精子和卵子可能在同一配子体上产生,所以蕨类可能会自我施肥。自我受精的优势在于浪费的孢子更少,不需要外部配子载体,适合其环境的生物体可以保持其特征。交叉受精的优势在于它可能会引入新的特征。 新西兰奥克兰大学植物学代写:蕨类植物周期 Starting with the "fern" as we recognize it (the sporophyte), the life cycle follows these steps:The diploid sporophyte produces haploid spores by meiosis, the same process that produces eggs and sperm in animals and flowering plants.Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis. Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid. This plantlet is much smaller than sporophyte fern.Each prothallus produces gametes via mitosis. Meiosis is not needed because the cells are already haploid. Often, a prothallus produces both sperm and eggs on the same plantlet. While the sporophyte consisted of fronds and rhizomes, the gametophyte has leaflets and rhizoids. Within the gametophyte, sperm is produced within a structure called an antheridium. The egg is produced within a similar structure called an archegonium.When water is present, sperm use their flagella to swim to an egg and ​fertilize it.The fertilized egg remains attached to the prothallus. The egg is a diploid zygote formed...
