Recommended: Essay on color vision
The letter does serve as a good introduction to the rest of the paper. The mantis shrimp states very clearly that it is concerned with its complex color vision. However, the mention of research makes it too detail. The “A different form of color vision in Mantis shrimp” study should be mentioned in the response. Yes, the material seemed to be ordered in a way that allows the author to slowly addresses the shrimp’s concerns. The author is using the research studies to provide a response. The in-text citations are not consistent. There are a few that do not have the names capitalized, while others use the scientist’s first name instead of their last name within the citation.

Save the Whales, Screw the Shrimp is an essay written by Joy Williams, about the overwhelming complacency that todays culture shows towards nature.Williams argues in a very satirical way, that todays culture has all but completely lost touch with what nature really is, and that unless we as a nation change our morals regarding the role that nature plays in human existence, we may very well be witnessing the dawn of our own destruction.
Barlow (1953) first postulated the existence of feature-sensitive ganglion cells in a frog’s retina based on an inhibitory-surround structure of the receptive field. He maintained that the “on-off” units of these cells triggered by the presence of a particular stimulus corresponded to certain behaviour in the frog. For example, presenting a spot of light in the visual field would cause certain neurons to fire in a particular ganglion cell, and in a live frog, would cause the frog to snap at the stimulus. Barlow concluded that these cells must be “fly detectors”. Lettvin et al. (1959) further examined the visual mechanisms of the frog and discerned fo...
The author of this article then goes on to explain the scientific experiment, but she barely sites the scientific research performed. In the third paragraph of the article she writes, “And as they have died, their brains have been removed and shipped in plastic tubs to a laboratory where they are analyzed and stored in jars.” She tells the reader that the nuns’ brains are being researched, but she does not state the cause. What are the scientists trying to prove by analyzing these brains? She leaves this question unanswered. This article shows various signs of weakness in the area of scientific research. Another example of this is found towards the middle of the article when she goes on to explain the daily testing the nuns perform. They undergo physical and cognitive testing, and afterwards the nuns receive reports of their results to see if their performance has altered.
Different wavelengths of light determine what colors we see in fish and other organisms. For instance, the changes of season affecting length of daylight triggers many species in the wild to change into their extreme breeding dress. Scientific studies exhibit numerous reports of fish that faded in color after becoming blind, an observation that would have some implications for fish kept in the dark.
I know my subject by his first name only, Maynard, by listening to his frequent conversations with his close friend Rolando I have discovered they enjoy talking about alcoholic beverages, movies, and video games among other things. He is of average height and a slim build with frizzy short black hair and wears glasses.
...s passage he references “scientists” as the information source, but does not cite any specific people or research.
Peripheral vision is used amongst every species ranging from a deep-sea marine animal to a bird flying hundreds of feet above the ground. However, each species’ vision differs to some degree and also differentiates within the species itself. This can be due to various types of eye conditions.
An inspection of the modern animal phyla will reveal that eyes are just as diverse as they are complex. Some organisms like the rag worm have pigmented cup eyes while other like he box jellyfish have two lens eyes and two pairs of pigment pit eyes. To account for the diversity in eye structure, we must first examine the eye ‘prototype’, the original structure that was acted upon by evolution. The simplest organ that can be considered an eye is composed of a single photoreceptor cell and a single pigment cell, without any lens or other refractive body (Arendt, 2003). Such organs are know as eyespots, and...
Moderata Fonte’s Venetian ladies debated the worth of women while cavorting in their fictional garden in 1605; Tempel Anneke met her unhappy fate in the 1660s. The seemingly enlightened and forward-looking feminist attitudes articulated in Fonte's text were absent from the Brunswick courtroom where the allegations against Tempel Anneke eventually brought about her death. The two accounts illustrate the differences in the attitudes towards women between European states during the 17th century. The differences are technically religiously based, however, they deal with the differences of the specific regional factors of the areas discussed. The differences explain why the attitudes of Fonte’s ladies and the persecutors of Tempel coexisted in roughly the same era. Fonte's ladies are Italian Catholics, and Anna's neighbors are German Protestants, therefore, the ideals of women are varied based on religious experience. Additionally, the theory of reason of state that came about with the consolidation of authority consisted of centralization and secularism that subordinated the social role ...
The central idea of the paragraph entitled “Restaurants in hot water with PETA for serving still-moving octopus, shrimp”, written by Los Angeles Times, is that live slaughter of seafood is not right and that this item should be taken off the table. Firstly, the author of the Newsela article states that, “The group hopes consumers will pressure legislators to ban the practice. But the organization hinted it may not stop there. "We're taking no other options off the table until live animals themselves are taken off the table," said spokesman Ben Williamson.” This is explaining that they are trying really hard to get live seafood off the menu, but they will have a hard time succeeding. All they are doing is trying to stop this slaughter, because
In Ireland in the years 1845-1852 a great famine caused a mass die off of potato crops throughout the country. Beginning in 1845 the weather in Ireland were abnormally chilly and damp for a summer season in Ireland, providing the perfect type of whether to allow diseases to spread rapidly. Phytophthora infestans, the cause of the great famine, can spread in the blowing wind. Shortage of food caused many Irish people to immigrate to other countries yet, some citizens of Ireland stayed most of which became struck will illnesses or died of starvation. Many farmers consolidated their land and shared the harvested crops creating another shortage of food for consolidated farming families. Potatoes originated from South America. . In the 1800s Ireland’s population grew immensely so, lands owners did not own more than a couple of acres for only themselves.
Suggested by its name, the octopus’ sixty or so blue rings light up in an iridescent fashion. The colorful rings extend from the head down to the body and arms of the creature on an otherwise dull body. As observed by the recorded video of the octopuses being disturbed, the rings were quick to light up with a dark brown colored outer circle, and a blue-green center. This display could be accomplished in as fast as 0.3 seconds, up to a little over 0.5 seconds. They noted that this brown ring of chromatophores along the edge increases the distinction between the rings and the pale
Peter makes one good point, and another is, they probably don’t want to eat the shrimp raw. It’s ok to eat it raw, but the main hassle is to rinse every single shrimp you catch. I think that the children wouldn’t have tolerated the huge fuss.
Deilephila elpenor moths were trained to associate a sugar reward with a color, either blue or yellow by feeding from colored artificial flowers at a light intensity equivalent to late dusk.
