Elodea
Elodea is a genus of aquatic plants often called water weeds. Elodea
is native to North America and it is also widely used as aquarium
vegetation. The introduction of some species of Elodea into waterways
in parts of Europe, the Australia, Africa, Asia, and New Zealand has
created a significant problem, and it is now considered a noxious weed
in these areas.
Elodea canadensis, sometimes called American or Canadican waterweed or
Anacharis (a former scientific name) is widely known as the generic
water weed. The use of these names causes it to be confused with
similar-looking non-native plants like Brazilian elodea (Egeria Densa)
or hydrilla (Hydrilla verticillata). American waterweed is an
attractive aquarium plant, and is a good substitute for Brazilian
elodea since it is native to Washington's lakes, ponds and rivers.
American waterweed is usually fairly easy to distinguish from its more
notorious relatives, like Brazilian elodea and hydrilla. All of them
have leaves in whorls around the stem. However, American waterweed has
three leaves per whorl, whereas hydrilla and Brazilian elodea almost
always have more than three leaves per whorl. Brazilian elodea is also
a much larger, bushy plant with longer leaves. American waterweed also
looks very much like another native elodea, Elodea nuttallii, which
generally has three narrower leaves per whorl.
The American waterweed lives entirely underwater with the exception of
small white flowers which bloom at the surface and are attached to the
plant by delicate stalks. It produces winter buds from the stem tips
that overwinter on the lake bottom. It also often overwinters as ...

The Canadian Pondweed grows better in cooler water. In temperatures
above 70º F, it becomes spindly. This plant can be grown under 8 to 10
feet of water and will easily reach the surface of the average water
garden. This plant derives most of its nourishment from the water
through its leaves; its roots serve mainly to anchor it to the bottom,
therefore, they may be planted in sand or pea gravel as well as soil.
They may be anchored down and just dropped into the pond or planted in
containers of sand or gravel. If they are only floated in the pond,
too much sunlight and air will kill it. If fish don't keep this plant
in check, it will need to be pruned back to prevent it from choking
other water plants and taking up swimming space for fish.
It is because cooler temperature favors the plant to more and enhances the metabolic activities. The enzymes present for producing carbon dioxide is able to produce more than the required under perfect climatic conditions. On the other hand, when we look at “Elodea heat”, we see it produce the least amount of carbon dioxide. This is because the enzymes cannot handle the heat that it is exposed to and after a certain period of time, it could rapture hence resulting in lesser amount of carbon dioxide produced. The stress level for elodea is too much at higher temperature. This is why we needed more drops in the “Elodea cool”
In the midst of a war, the question of its purpose and legitimacy arise. In Aristophanes' Lysistrata, the protagonist, Lysistrata, revolts against the trivial Spartan and Athenian war that lasts for more than two decades and persuades other women to strike against the men by taking an oath of celibacy until the soldiers put down their arms. Aristophanes, using several scenes, advocates his desire for the bloodshed to cease by satirizing the folly of the war and making its supporters, the men, look foolish.

Olaudah Equiano The slave trade, yet horrific in it’s inhumanity, became an important aspect of the world’s economy during the eighteenth century. During a time when thousands of Africans were being traded for currency, Olaudah Equiano became one of countless children kidnapped and sold on the black market as a slave. Slavery existed centuries before the birth of Equiano (1745), but strengthened drastically due to an increasing demand for labor in the developing western hemisphere, especially in the Caribbean and Carolinas. Through illogical justification, slave trading became a powerful facet of commerce, regardless of its deliberate mistreatment of human beings by other human beings.
The autobiography of Olaudah Equiano, first published in 1789, is the first example of a slave narrative. Unlike most of the class, I took it upon myself to read the entire story of Equiano’s Travels, abridged and edited by Paul Edwards. In that version, as in the version represented in The Norton Anthology American Literature Shorter Fifth Edition, the journey of Olaudah Equiano is expressed in his own words, from his own point of view. That makes this writing a truly unique piece of literature. It is not only the first slave narrative but also one of the only ones written pre-civil war by a former slave, and someone seized from Africa. These facts give the writing a unique feel, for it is the words of a man that was born a free man, raised to be a ruler of his tribe, kidnapped and made into a slave as a young child, and then journeying through life to become once again free as a mature adult. Equiano experienced almost all parts of a slave’s existence. He was a slave throughout Africa, England, and the New World.
Just as with Erec, the origin of Enide is widely debated. There are two basic theories of how she came into existence in medieval literature. One theory is that it was Chretien De Troyes who created the characters Erec and Enide, and it was the Welsh that drew off of Chretienís work in order to fabricate their own tales of the two (Owen xvi). This theory may have evolved due to the fact that "Wales contributed very little, or even nothing of importance to the Arthurian legend as it developed in France, and Germany and then in England" (Jones and Jones xxv). Chretien was therefore given the credit because of his extensive writings on the Arthurian legends, and the fact that he was French. However, a more widely accepted theory is that the story of Erec and Enide was derived from the Welsh (Jones xxv). Evidence supporting this theory is that of the "comparative folktale, of proper names and linguistics, and what may be reasonably if tentatively deduced from the methods of literary composition in the Middle Ages" (Jones xxvi). Due to the fact that no one is sure who wrote about Enide first, the task of finding where she first appears in literature is daunting undertaking. Nevertheless, we are able to fill in some of the gaps as to where Enide is mentioned in some texts. Circa 1170, Chretien De Troyes wrote Erec and Enide that can be found in Chretienís collection entitled Arthurian Romances. Erec also appears in The Mabinogion, another collection of Arthurian tales. In this book, Erec, also called Geraint, appears in the tale Geraint son of Erbin. Lord Alfred Tennyson includes Enide in two out of the four Idylls of the King. Both "The Marriage of Geraint" and "Geraint and Enide" were written between 1809 and 1892. Enide also appears in some lesser-known, more modern works. These include two plays: Ernest Rhyís Enid: A Lyric Play (1918) and Donald R. Raweís Geraint: last of the Arthurians (1972), and Marion Lee Reynoldsí poem Geraint of Devon (Lupack).
influenced the perception of African Americans in England forever. He was taken from his home in Africa by slavers when he was young and separated from his family. However, he eventually bought his freedom and moved to England to affect the abolitionist movement there. Even though he had a rough start to his life, Olaudah Equiano rose above the hardships to had a great influence on the abolitionist movement and shed a light on the injustices of the slave trade.

Aristophanes was a craft comedy poet in the fourth century B.C. during the time of the Peloponnesian War. Aristophanes’ usual style was to be satirical, and suggesting the eccentric. The most absurd and humorous of Aristophanes’ comedies are those in which the main characters, the heroes of the story, are women. Smart women. One of the most famous of Aristophanes’ comedies portraying powerfully capable women is Lysistrata, named after the female lead character of the play. It depicts Athenian Lysistrata and the women of Athens teaming up with the women of Sparta to force their husbands to conclude the Peloponnesian War. The play is a comedy, which appears to be written for the amusement of men. The play can be seen as a historical reference to ancient Greece, but it seems highly unlikely that women would talk with such a crude sexual tone. Instead Lysistrata is strictly a satirical play written maybe even to make men doubt the innocence of a woman.
In 1745, Olaudah Equiano was born in a small village in Isseke,Nigeria. His father was one of the chiefs in the village. At age eleven Equiano and his sister were kidnapped by two men and a woman never to see his home or parents again. After being kidnapped he was hiked across part of Africa untill he arrived at the coast where he was loaded onto a slave ship. While crossing the Atlantic to Barbados onboard the slave ship he and his countrymen were subject to horrors you could hardly imagine. Equiano tells about the horrors and torture slaves face not only on the slave ship but also on plantations and many other aspects of a slave's life. Equiano experienced almost all parts of a slave's existence. He was a slave throughout Africa, England, and the New World. Equiano is bought and sold several times. Religion also played a huge role in Equiano's life and I think that it helped him get through some really hard times. He is bought by a British Naval officer and serves in the British Navy during the Seven Years' War. He is then sold to Robert King where he begins trading goods between islands and eventually makes enough money to buy his freedom. Equiano tells of the joy he feels when he becomes a free man. The rest of his life is devoted to helping slaves and to the cause of abolishing slavery.
Olaudah Equiano (Gustavus Vassa) was kidnapped from his African village at the age of eleven, shipped through the arduous "Middle Passage" of the Atlantic Ocean, seasoned in the West Indies and sold to a Virginia planter. He was later bought by a British naval Officer, Captain Pascal, as a present for his cousins in London. After ten years of enslavement throughout the North American continent, where he assisted his merchant slave master and worked as a seaman, Equiano bought his freedom. At the age of forty four he wrote and published his autobiography, The Interesting Narrative of the Life of Olaudah Equiano, Or Gustavus Vassa, The African. Written by Himself, which he registered at Stationer's Hall, London, in 1789. More than two centuries later, this work is recognized not only as one of the first works written in English by a former slave, but perhaps more important as the paradigm of the slave narrative, a new literary genre.

An ironsmith, ship steward, crewman, cook, clerk, navigator, amateur scientist, and even a hairdresser. These are all jobs that Olaudah Equiano held during his lifetime. He has been called the "most influential African writer in both Africa, America and Britain before the Civil War", and was born in Essaka, Nigeria sometime during 1745 (O'Neale, 153). His family was part of the Ibo tribe, which was located in the North Ika Ibo region of Essaka. In his earliest years, Olaudah Equiano was trained in the art of war. His daily exercises included shooting and throwing javelins. As he states in his autobiography, two men and a woman, who came over the walls while the rest of the family was away, abducted Olaudah and his sister in 1756 (Equiano, 356). He was only eleven years old. The two of them would only be reunited when Equiano was sold a second time. They did not remain together that long because he would be sold again.

I believe that the ending of the Aeneid shows that Aeneas is very heroic. According to Webster’s New Dictionary, “a man of distinguished bravery” and “admired for his exploits.” Aeneas is very brave when he fights Turnus, especially because it is known that the gods are on his side. He successfully killed Turnus, which is an achievement that calls for admiration.
