The process of color change in chameleons is simply fascinating. What happens is that chameleons have a top layer of the skin that is transparent, and underneath it there are layers of skin, which contain chromatophores (these are specialized cells that contain pigment). Beneath the transparent layer, there is a layer with xanthophores (contains yellow pigments) and erythrophores (contains red pigments). Under this layer is layer with iridophores (contain blue pigments). At the bottom are melanophores (contain melanin. Despite the popular belief, chameleons don’t change colors on the whim to match their environment, but instead to communicate change in mood or temperature. In these occasions, their chromatophores either expand or contract,
The predictions that were made prior to the experiment being ran about the concentration of pigments in Drosophila were similar to the observed concentration of pigments. Once four fly heads of each pigment were crushed onto filter paper, chromatography was ran. After six hours of the chromatography being run, they were removed from the solvent and dried. Once the filter paper was dry, it was placed under a UV light for a better observation of the pigments present in the eyes of the fly. What was found in the white was much less than in the wild type due to the fact that in the white eyed fly, both enzymes that start the pigment production (the pteridine pathway and the ommochrome pathway) are blocked or changed so no pigments can be produced.
eyes). They can also change the size of their melanophores to adjust colors slightly, giving them an
Pigments-pigments change the colour from the natural colour to make it more pigmented which is making the colour stronger and
melanogaster Egg. The above figure shows an egg from D. melanogaster stained with toluidine blue dye. The toluidine blue dye allows for the chorion to be visible since it is dyed in purple.
If any dark blue bugs remain, one of them will mutate. Flip a coin. If it is heads, it will mutate into a purple bug. If it is tails it will mutate into a green bug.
The Yellow Wallpaper and the Metamorphosis share a common theme of gaining a freedom from their previous lives. The lady in the Yellow Wallpaper is controlled by her husband and escapes by imagining herself as being the girl in the wallpaper. Gregor was responsible for supporting his family financially and he never took time for himself. He gains freedom by transforming from a human into a bug. The authors have illustrated the theme by conveying their changing mental states.
Have you ever wondered why the fourteen inch reptile, know as the chameleon can camouflage? If so, I'm here to tell you the Legend of Giroud. To begin, the chameleons are the original conquerors of the North America. They lived in peace in a calm environment, but then, things twisted in another direction. Their prey started to adapt to the chameleons strategies, and left the chameleons in a sticky situation. So the chameleons could no longer catch their prey to survive. Weakened by the food shortage, the chameleons became ill, weak, and started to die off. It started to decrease their population. A brave chameleon decided to help his fellow chameleons, to persevere this challenge. A chameleon in the name of Giroud stepped up to the plate. Let's jump in into Giroud's brave and heroic action,
The coats were colored using a natural dye from cochineal and madder. Cochineal are tiny beetles that are about 5mm long and have a flat, oval-shape with a soft body; they live and feed off cacti. As referenced in the article “The Royal Red of Natural Reds,” when the
The objective of this research is to investigate diversification rate shifts to see if there was a higher speciation rate in chameleons once they dispersed from Africa to Madagascar. My phylogenetic tree was built from 6-genes, multiple nuclear and mitochondrial markers and 174 taxa, it represents over eighty-three percent chameleon species. Using three different reconstruction methods, Bayesian and likelihood approaches it was seen that the family originated in Africa, with two separate oceanic dispersals to Madagascar. I will be using BAMM software to test diversification rates to see if there was colonization from Africa to Madagascar. There are three Malagasy genera found on the phylogeny
In the novel The Shading Purple, Alice Walker makes a feel of hardship, self-disclosure, and love through the distinct diary sections of a young lady developing into a lady. This story is described by Celie, a character uncertain about who she really is and who to trust to help her discover her direction. Her activities, at initially, appear to be weak trying to comprehend her own particular conditions, however as the story advances she starts to say and do things that are dissimilar to her. You start to scrutinize the correct way of Celie, in which she is named as ethically vague. The life and individuals that she is compelled to persist are the fundamental wellsprings of her being like this by any stretch of the imagination. In any case,
This brief article is written from the psychiatric perspective, pointing out that Kafka has always been of great interest to the psychoanalytic community; this is because his writings have so skillfully depicted alienation, unresolved oedipal issues, and the schizoid personality disorder and The Metamorphosis is no exception to this rule. While this writer tends to think that psychiatrists should read The Metamorphosis, many probably have not, and this paper serves as an excellent introduction to the work, from the perspective that the psychiatrists would value.
"Tabula Rasa"- the theory that individuals are born without essence and are shaped by knowledge and perception- is quite dubious. To what extent does the fact that multiple perceptions of a human being exist affect their identity? German-language writer Franz Kafka's novella "The Metamorphosis" and one of it's themes of the struggle to define one's identity answers some of these questions. Published in 1915, this story is a fictitious account of the protagonist, Gregor Samsa's transformation into a gigantic bug and the series of events which occur as he and those around him attempt to adjust to this outrageous transmutation. Throughout the novella, we see Samsa
The assignment was broken up into two parts. Each member had a device to configure Dan configured Branch1 router, Adam was assigned Branch2 router, Okoma configured the switch, PC, ISP, and Kevin configured the Core router. We did not receive a config from Adam so, Kevin was able to do that part too. Okoma and Dan provided a brief written summary of the work they performed and Kevin put the paper together.
In just five days I had my view of pornography taken apart, dissected and reassembled, and while I don’t believe my views on pornography have drastically changed, my perspective has certainly shifted. There truly is so much to consider when attempting to form an opinion of porn, it’s mind-boggling, but in many ways, it is essential. My genuine feeling after taking this course is that in a perfect world, everyone who enjoys pornographic entertainment, or is curious about it, would take this class. Because although my views on porn haven’t changed drastically, they are far better informed and I now feel equipped to defend them with gusto, should I ever have to do so. My initial self-reflection focused on my views on violence and addiction related to pornography. However, because there is so much to discuss, I limit myself in this self -critique to revisiting the subject of violence; mainly, I consider the cultural context of the relationship between pornography and violence, as well as contemporary research surrounding said relationship.
“ Shoot all the bluejays you want, if you cant hit ‘em, but remember it's a sin to kill a mockingbird. “ Racism persecutes innocent people for no good reason.
