Warm Blooded Versus Cold Blooded Dinosaurs
At a time, scientists believed all dinosaurs were cold-blooded. However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in 1993, many paleontologists are starting to think that there were some dinosaurs that were warm blooded.
Dinosaurs were first believed to be cold-blooded because they were thought to be related closely to reptiles which are cold-blooded creatures. Cold-blooded animals don’t actually have “cold” blood, instead they rely on the temperature from their environment to regulate their own body temperature. They do this by taking advantage of external heat by basking in the sun, and by lying in the shade to cool down. A more correct term is “ectothermic” which means “heat from outside.” On the other hand, a warm-blooded animal creates heat internally by chemical reactions inside their body. They are able to regulate their body temperature internally instead of relying on their environment. Author of the article, “Dinosaurs: Warm or Cold Blooded?” Beverly Eschberger explains, “endothermic animals have a continually high requirement for food to fuel the heat generation. Providing they can find food their constantly-optimum body temperature means that they can stay active even when it is very cold” (par 3). Even though it was believed that dinosaurs were closely related to cold-blooded reptiles, most dinosaurs had similar behaviors of a bird which is a warm blooded animal. Believing dinosaurs were warm blooded would help explain the reason why dinosaurs were so dominant and plentiful for such a long period of time. There are many other factors that play a vital role in ...

“The power of imagination makes us infinite.” (John Muir). Both John Muir and William Wordsworth demonstrate this through their use of language as they describe nature scenes. John Muir studies nature and in his essay about locating the Calypso Borealis he uses scientific descriptions to grab his reader’s attention and to portray his excitement at finding the rare flower. William Wordsworth on the other hand shows his appreciation for the beauty of nature and its effect on a person’s emotions in the vivid visual descriptions that he gives of the daffodils in his poem ‘I wandered lonely as a cloud.’ Wordsworth with his appreciation of beauty and Muir through scientific descriptions provide an indication of the influence that nature has had on them as they capture their reader’s attention both emotionally and visually through their personal and unique use of tone, diction, syntax and vocabulary.
Dinosaur fossils are one of the few ways in which scientists can study the history of life on earth millions of years ago. Each new discovery is unique in its own way and provides valuable information about the past. No two finds are exactly identical; therefore, when dinosaur remains are uncovered, the possibility and excitement of new information or even a new species exists. Until the year 2000, no dinosaur has ever been found with a fossilized heart. Scientists at North Carolina State University and the North Carolina Museum of Natural Sciences discovered a sixty-six million year old Thescelosaurus with a heart.
So what killed the dinosaurs? Without having any background education in science it is hard for the general public to comprehend such matters and they rely on the knowledge of the scientists in this field. Although there has been much research on the subject nobody has come up with a conclusive answer. And we are left to read the countless articles, all having their own opinions as to the mass extinction. One such theory is that a shift in the solar system could have caused the mass destruction. According to an article published in Nature magazine,
Every so often a discovery is made that attempts to shake up pre-conceived notions of how the dinosaurs actually lived or how they came to be. On June 22, 2000, in Oregon, scientists announced the discovery of the oldest known animal to have feathers. Though no records indicate how the age of the animal was determined, the fossil was dated at 220 million years old. It lived at the time of the very earliest dinosaurs, and about 75 million years before the first known bird.1[1]
When Emma plans her wedding to Charles, the readers learn: "Emma would have preferred to be married at midnight by torchlight" (p. 22). Instead, she settles for a traditional wedding. Charles adores Emma: "He was happy, without a care in the world…" (p. 28). Charles realized that he "possessed, for life, this pretty wife whom he adored" (p. 29). Emma, on the other hand, feels differently. Through the narrator, the readers learn her inner thoughts:
The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists.
The poem says that "since feeling is first" (line 1) the one who pays attention to the meaning of things will never truly embrace. The poem states that it is better to be a fool, or to live by emotions while one is young. The narrator declares that his "blood approves" (line 7) showing that his heart approves of living by feeling, and that the fate of feeling enjoyment is better than one of "wisdom" (line 9) or learning. He tells his "lady" (line 10) not to cry, showing that he is speaking to her. He believes that she can make him feel better than anything he could think of, because her "eyelids" (line 12) say that they are "for each other" (line 13). Then, after all she's said and thought, his "lady" forgets the seriousness of thought and leans into the narrator's arms because life is not a "paragraph" (line 15), meaning that life is brief. The last line in the poem is a statement which means that death is no small thi...
"since feeling is first" is a free verse poem and the speaker is specific persona created by the author. The persona that Cumming created is a man deeply in love. This poem has 16 lines in total and is structured in stanzaic form. The stanzas are grouped together with syntax errors. There is no proper punctuation which makes the reader confused of making pauses. There is enjambment; where the lines are broken after a completion of thought. For instance, stanza one contains four lines and those four lines have no proper punctuation. To make sense of that stanza, it should be read together. The author has purposely made this syntax error because he compares life to a paragraph (line 15). He had to show that life is not structured like a paragraph. Life lacks the logical order the paragraph contains. The speaker of this poem is a man who is in love and believes that there is nothing better. The tone of the speaker is romantic and realization. Literally, the speaker is in love and he thinks nothing is greater than love. There is nothing that can come among love. Figuratively, the poem is about the people forgetting to realize the great things in life because they pay attention to trivial matter and tend to lose something prom...
Another form of Emma’s neglect is one of manipulation, mostly through her control over Harriet Smith. Emma is “willful, manipulative, an arranger or rather a misarranger of other people’s lives. Much of the time she fails to see things clearly and truly, and her self-knowledge is uncertain” (Goodheart)25. “One significant effect of harping on Emma's snobbery is to set in relief her romantic notions of Harriet's origin and destiny” (Brooke)26. Although to Harriet, Emma’s “help” to her is one that will reveal optimistic results and a proper husband, Harriet is incapable to taking up for herself against Emma, but if “[s]he would form her opinions...
As President Lincoln once said, “Character is like a tree and reputation its shadow. The shadow is what we think it is and the tree is the real thing,” too often mankind are too quick to judge others by their appearance rather than who they truly are (Good Reads). Often times, people judge one another not solely by their character that is the true indicator of who they are but by their reputation or appearance. Throughout the novel, Emma, by Jane Austen the themes of appearance vs. reality, marriage and confinement of women, and social status are portrayed through characters such as Emma, Harriet, and Mr. Knightley.
In “I wandered Lonely as a Cloud,” William Wordsworth accomplishes his ideal of nature by using personification, alliteration, and simile within his poem to convey to the reader how nature’s beauty uplifts his spirits and takes him away from his boring daily routine. Wordsworth relates himself in solidarity to that of a cloud wandering alone, “I wandered lonely as a cloud” (line 1). Comparing the cloud and himself to that of a lonely human in low spirits of isolation, simultaneously the author compares the daffodils he comes across as he “floats on high o’er vales and hills” (line 2) to that of a crowd of people dancing (lines 3-6 and again in 12). Watching and admiring the dancing daffodils as he floats on by relating them to various beauties of
In Jane Austen’s social class and coming of age novel, Emma, the relationships between irony, insight and education are based upon the premise of the character of Emma Woodhouse herself. The persona of Emma is portrayed through her ironic and naive tone as she is perceived as a character that seems to know everything, which brings out the comedic disparities of ironies within the narrative. Emma is seen as a little fish in a larger pond, a subject of manipulating people in order to reflect her own perceptions and judgments. Her education is her moral recognition to love outside her own sheltered fancies and her understandings of her society as a whole.
Through the poems of Blake and Wordsworth, the meaning of nature expands far beyond the earlier century's definition of nature. "The road of excess leads to the palace of wisdom." The passion and imagination portrayal manifest this period unquestionably, as the Romantic Era. Nature is a place of solace where the imagination is free to roam. Wordsworth contrasts the material world to the innocent beauty of nature that is easily forgotten, or overlooked due to our insensitivities by our complete devotion to the trivial world. “But yet I know, where’er I go, that there hath passed away a glory from the earth.
The poem “I Wandered Lonely as a Cloud” by William Wordsworth is about the poet’s mental journey in nature where he remembers the daffodils that give him joy when he is lonely and bored. The poet is overwhelmed by nature’s beauty where he thought of it while lying alone on his couch. The poem shows the relationship between nature and the poet, and how nature’s motion and beauty influences the poet’s feelings and behaviors for the good. Moreover, the process that the speaker goes through is recollected that shows that he isolated from society, and is mentally in nature while he is physically lying on his couch. Therefore, William Wordsworth uses figurative language and syntax and form throughout the poem to express to the readers the peace and beauty of nature, and to symbolize the adventures that occurred in his mental journey.
William Wordsworth has respect and has great admiration for nature. This is quite evident in all three of his poems; the Resolution and Independence, Tintern Abbey and Michael in that, his philosophy on the divinity, immortality and innocence of humans are elucidated in his connection with nature. For Wordsworth, himself, nature has a spirit, a soul of its own, and to know is to experience nature with all of your senses. In all three of his poems there are many references to seeing, hearing and feeling his surroundings. He speaks of hills, the woods, the rivers and streams, and the fields. Wordsworth comprehends, in each of us, that there is a natural resemblance to ourselves and the background of nature.
