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.

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.
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).

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 Eldred’s essay, she argues that he adopted son, William, lies because they were adopted. From my interpretation, Eldred explains that not only her children, but also other adopted children may display emotional issues (which include lying). There were a few different didactic meanings that I felt Eldred touched base on, but her point of view on lying is very interesting.
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.
In Oedipus Tyrannus, the cultural way of thinking has been challenged by Oedipus himself and also the queen of Thebes, Jocasta. Oedipus is a king of Thebes who claimed himself to be incredibly smart for solving the riddles and he has helped the city who happened to be falling apart from the missing of their king. While in searching for the murderer of Laius, Oedipus called upon the presence of Teresias – the blind prophet. Oedipus requested Teresias to inform him about the truth that he knew about the secrets of the heaven and the earth (Sophocles, 1970). As a king Oedipus looked at himself as the one who hold the power and Teresias is expected to give what he asked for. However, Teresias refused to answer Oedipus’ question. He describes this
Amidst the tone of war around us, and speak of possible defeat, the festival of Dionysos will be held the fall of this great year, 411 BCE. Many ideas of entertainment have been suggested, most of which plays from various credible playwrights. One that has caught my eye in many ways is a work by Aristophanes. It is titled Lysistrata, and is a comedy based on our current status of war. Now considering our present situation, this may seem like a ludicrous idea. The wrong choice of words in a public address can result in a revolt, let alone a play that will be seen by many more citizens than will a public speaking. Why choose such an idea? Well, there are many reasons, and I intend to explain them to you.
Many argue that throughout Aenied, Virgil develops Aeneas to be a boring and unheroic character; always acting as he should with apparently no power to act in any other way. Occasionally sidetracked, Aeneas is prodded and redirected by the gods toward his destiny. Aeneas’ mother, Venus, constantly interjects to lead Aeneas toward his fate. It is she who leads him away from the fallen city of Troy “ I had twice-ten ships, and my goddess-mother showed me the way.”(I, 541-542) Mercury also sets Aeneas straight from his deviating course by telling him to leave his love Dido “What are you pondering or hoping for while squandering your ease in Libyan lands.” (IV, 362-363) Mercury criticizes Aeneas for ignoring the importance of his empire, and again Aeneas obeys. It is further argued that Aeneas’ makes no significant effort to advance his empire’s fate. He is “handed” all that is needed such as immortal vessels as well as weapons and armor provided by Vulcan and other gods. At first glance this would seemingly prove that Aeneas is in fact a boring character.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
Although, this experiment is not concluded outdoors, it is provided with efficient light that promotes growth. It’s provided with soil, seed, fertilizer, water and NaCl solutions, to test how salinity effects plant growth.
...fully transformed the shows the plants that were transformed were able to thrive in high levels of 2,4-D. The control (wildtype) was unable to grow in any concentration of 2,4-D
English class is a place where we can learn many things, one of them are short stories, this is a fiction work with a fully development theme but significantly shorter and less elaborated than a novel that require the following elements, characters, setting, conflict, point of view, theme, and plot. For an example of a short story I will mention “The Everest Story” this is a book that we already read in this class, and another example I have is the “The Thirty-Nine Steps”, this is a book we are reading and I will give my opinion of it.
Politics, family feuds, and land disputes are just a few things that can destroy a community. They may be idiotic arguments but they exist in almost every community. When you think about a community free of arguing and disagreements, those three issues would not exist. There would be peace, happiness, and no discussion of politics at the dinner table because we all know how that ends, poorly. Everyone would treat their neighbors the way they would want to be treated. People would say, “bless you”, to everyone, no matter who sneezes. It would be the most joyous community. In my own community of Alpena, we are not extremely rude or terrible. We do not have huge family feuds or land disputes. The one thing that Alpena needs to work on is manners,
