0. Title Page Ecology of Life Lab Courtney Patton 3/16/16 - 4/1/16 1. Introduction: During this project, we tested if washing your hands multiple times would affect the bacteria growth on your hands. I think that the more you wash your hands, than there would be less bacteria growth each time. This experiment will help to show us just exactly how the bacteria on our hands if affected as we wash them. This way we will be able to see the bacteria better because a single bacteria would need a microscope to be visible to the human eye. Since I wiped my finger on the agar plate, the bacteria will grow fast and will start to form colonies of bacteria. After the bacteria forms colonies, you won’t need a microscope to be able to see the bacteria. This will show us how washing your hands can keep you from getting sick or spreading a sickness you already have. 2.

male and female relationships Essay - 592 Words

Female vs. Male Friendships nbsp;nbsp;nbsp;nbsp;nbsp;Male and female friendships are different and alike in many ways. They differ in how men and women can relate to each other both physically and emotionally. Men and women also differ in the communication aspect. In both friendships, there is a certain level of competitiveness, and the friends obviously will have the same interest in common. Friendships will differ from person to person because of the different personalities, but there will be the same likes and differences. nbsp;nbsp;nbsp;nbsp;nbsp;Physical and emotional closeness definitely is different for men and women friendships. Women can be physically close to each other and be very comfortable, for example sleeping in†¦show more content†¦For example, when women don’t talk to each other for a couple of days, sometimes those days will be seen as the friendship is coming to an end. If a man does not talk to his friend on a regular basis, to a man that just means that their friend is either busy or is just hanging with other friends. Men are better with confrontation then women. A man will come right out and tell his friend that he is upset with his actions, whereas a woman will act as if nothing is wrong and continue the friendship and eventually blow up at her friend. nbsp;nbsp;nbsp;nbsp;nbsp;In both friendships, there will be a certain level of competitiveness, whether or not the sexes admit to it. Both men and women compete for the opposite sex. There are other things that they compete at such as academics, sports, looks, video games and just about everything in general. No matter if it is a male to male, female-to-female or female to male, in all friendships there must be a common interest. Without that interest, there is no friendship. Whether it is a mutual friend or what kind of beer you like, that interest must be present or there is no reason for the friendship. nbsp;nbsp;nbsp;nbsp;nbsp;Different personalities will obviously determine who will be friends. Male and female friendships are alike in that they both are seeking friends with the same interest and they compete with each other.

Rhode Island Free Essays

Cotton is estimated to have been grown, spun and woven into clothes in Pakistan, in the Indus River valley, 3000 years B. C. The natives of Egypt Nile valley also used cotton to make clothes at the same time. We will write a custom essay sample on Rhode Island or any similar topic only for you Order Now Cotton was introduced to Europe by the Arab merchant about 800 AD cotton was found growing in the Bahamas Islands in 1492, a discovery by Columbus. Cotton became known worldwide, by 1500. Cotton was first planted in 1556 in Florida and 1607 in Virginia. In 1730 cotton was first spun by use of machinery in England. This led to the industrial revolution and later invention of the cotton gin in US that paved way for the modern cotton industry. A patent of gin in 1793 was secured by a native of Massachusetts known as Eli Whitney. The machine would do the work 10 times faster than by use of hand. The gin made it possible for the later fast growing textile industry. The supply of large quantities of cotton fibre led to the growth of cotton growing in the early 1800s. Cotton had its importance in late 1700s and early 1800s; the research paper will be discussing cotton’s importance then. Earlier on James Hargreaves in 1760s invented the spinning Jenny which was later improved on by Richard Arkwright (Waterwheel Spinning Frame). Springing up of textile mills and cottages for imported workers was to follow. This saw the birth of factory system with the first successful system of mass production. Others who contributed to industrial revolution in cotton production included; Fulton’s steamboat in 1807, Stephenson’s locomotive in 1825, Cyrus McCormick’s reaper in 1831, the Howe-singer sewing machine in 1854 and Sir Henry Bessemer’s converter in 1858. Discussion Cotton growing in the early 1800s led to the textile industry development. For example the invention of spinning machines led to further improvement to produce better machines to be used in the textile industry. James Hargreaves invention of spinning Jenny in 1760s resulted to further improvements on the machinery. The inventions led to the industrial revolution, which led to the increased production of cotton. The textile industry grew very fast to produce cotton fibre, which were used by the people in the early 1800s. Cotton growing led to the improvements in transportation system. Coal was required as fuel and iron for the new machinery in the cotton textile manufacturing. Both coal and iron mining increased to provide raw materials for the manufacturing companies. New roads were developed to satisfy the transportation requirements. There was the development of rail roads and steamships for easy access of mines and easy supply of the material to the textile industries. Employment was created in the newly created factories. Between the years 1793-1858, invention of cotton gin, steam engine, steamboat, locomotive, sewing machine and the converter was seen. The cost of producing cotton clothing was lowered by the introduction of the new devices. This created a worldwide demand for cotton. The farm workers in the cotton farms were freed to enter into the newly created factories. This promoted employment of the people in the factories. Cotton enhanced huge amount of capital investment by the south. The south region due to increased rate of cotton manufacturing invested a lot of capital and labor in cotton growing plantations. Profits were made by big planters by use of slaves in labor. For example Mississippi in United States quickly developed an economy based on growing cotton. This led to the growth of the economy in years that followed. Development of electric power was as a result of shortage of waterpower in Mississippi. The advent of steam power later led to the development of electric power. In the given economy electric power increased efficiency and led to rapid growth of the cotton industry in other regions. The economy was able to grow very fast due to increased revenue and investment. Cotton growing led to the growth of the agricultural economy. New species of cotton were introduced to maximize the yield. Use of slave lab our and poor payment of workers reduced the textile’s industries expenditure. High revenue was channeled back to move production of cotton. The cotton plantations continued to increase in number enhancing growth of the agricultural sector. On the other hand cotton growing promoted the use of slave labor in the plantations for example, cotton manufacturing in the south led to investment of capital and labor in cotton growing. The big plantations used slave labor. The slaves would do a lot of work without payment. Slaves were exploited by cotton manufacturing industries to provide labour in their farms. Worker’s had very poor living and social conditions. Apart from the slave labour, those who were employed in the plantations were paid very poorly. The workers could not afford to live well due to the low income they earned from the cotton farms though they continued working. This influenced the later movement of people from the colonial farms to the urban areas in search of greater income and better working conditions. There was use of child labour in cotton growing. In Rhode Island, Samuel Slater in 1970 reconstructed spinning machines to establish a 72-spindle mill (first successful water-powered spinning mill in America) . Young children between 7-12 years were employed to operate machines. This left cabin and domestic weavers to weave yarn into cloth. This was referred to as â€Å"Slater or Rhode Island system’ and was later emulated by manufacturers in other states. Cotton production increase can be attributed to the inventions of machines in the textile industry, availability of cheap or slave labour and increased investment of capital and growth of the agricultural economy with time. In 1973, the south produced 10, 4510 bales of cotton, then 177,824 bales in 1810 after the invention of cotton gin. This later increased to up to 7 million bales by 1850. In conclusion, cotton had both positive and negative effects on the economy of the states where it was grown in the early 1800s. From those many years, cotton has become one of the most important textile fibre in the world. From few regions where it was grown, it has spread to many areas while technological advancements have increased its productivity. References Paul . S, Neal S, Clifford. C, Kett. F, 2008.

If youve ever seen the classic James Bond flick Thunderball, you probably remember that great action scene in which 007 makes his escape from some bad guys by slipping on a rocket-equipped backpack and blasting off into the sky [source: Parker]. Jet packs were first dreamed up by German scientists during World War II, and after the war, the Pentagon longed to develop its own version [source: Kaku]. In the 1950s, at Bell Aerosystems in New York, a visionary engineer named Wendell F.  Moore created his own version of the concept, a 125-pound (57-kilogram) rocket belt powered by a canister of liquid nitrogen. For its part, the U. S. military eventually gave up on jet packs as a practical mode of battlefield transportation, in part because flyers could only carry enough fuel to stay aloft for less than half a minute [source: Rocketman. com]. But we are getting really close to the jet packs we were promised. We will write a custom essay sample on Inventions of the future or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page New Zealand-based Martin Aircraft has approval for manned test flights of its P12 Jetpacks. And although the company has sent unmanned packs 5,000 feet (1,524 meters) in the air, these manned flights will only be 20 feet (6 meters) over land and 25 feet (7. 6 meters) over water [source: Oremus]. And guess what the company is taking orders. Law enforcement and government agencies can order one for an expected mid-2014 release, and private jet pack enthusiasts (and who isnt) can get on a waiting list for a possible 2015 purchase [source: Martin Jet Pack]. ROBOT MAIDS The most obvious answer to a complaint about the lack of robot maids is of course, Hey, buddy, go buy a Roomba. Because while they dont really resemble George Jetsons robotic maid Rosie, modern bots do carry out a host of floor vacuuming, tile scrubbing and pool cleaning chores. Of course, the vision of the computerized maid goes beyond mere automated dust busting. What weve been waiting for is a true robotic domestic servant capable of safely navigating a human living environment to carry out everything from cleaning the toilet to cooking pancakes. But in order to actually move through our kitchens and interact with us, robots will need to be capable of social learning. A truly social bot will need to evaluate environmental stimuli with a discriminating eye. In short, a true robotic maid would need to be autonomous. Scientists from Cornell University are on the case, and are slowly creating robots that might be able anticipate human needs. They predict that in the next few years we might see a robot maid who can do some specific tasks. So far, theyve already developed a robo-maid who can open a fridge and pour you a beer [source: Carroll]. A far greater help than, say, folding laundry. ATOMIC POWERED HOMES In the 1950s, when the U. S. government first approved the creation of nuclear plants for generating electricity, some Americans fantasized about a future in which small, personal nuclear reactors would be commonplace gadgets. In 1955, Robert E. Ferry, general manager of the Institute of Boiler and Radiator Manufacturers, gave a speech in which he predicted that individual homes would be heated and cooled by small reactors within three to six years. Although that hasnt happened nearly 60 years later, there was some movement to create mini-reactors that might power small communities or even homes. As recently as 2008, company Hyperion Power Generation (now Gen4 Energy) was claiming that it had developed nuclear power plans smaller than a garden shed that could power 20,000 homes and would be on sale by 2013 [source: Vidal and Rosen]. However, 2013 hit, and still no progress on this nuclear sunset.
