An Example Of Complete Metamorphosis In Prostomes

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.

One of the most prominent themes present in Franz Kafka’s The Metamorphosis is isolation. Gregor, transformed into a vermin, becomes extremely isolated by both his family and society. Gregor’s family, job, and apartment contribute to this sense of isolation significantly, both in a literal and figurative sense. The sense of isolation that Gregor feels as a result of his metamorphosis, however, is not unique; in fact, isolation is common in every aspect of society as a whole. Gregor’s transformation, therefore, is an allegory for the inherently isolating and alienating nature of the human condition.

They must be eukaryotic, meaning they have nucleus, and in the domain Eukarya. In the Linnaean classification this could be in the kingdom Protista like a paramecium. Another Linnaean classification of this could be in kingdom Animalia, since they are heterotrophs and their cells contain a nucleus. They could be grouped as predators, since the organism is engulfing another organism. They could also be grouped based on their locomotion. They could have cilia, legs, or even flagella.

Metamorphosis is often described as a change of the form or nature of a thing or a person into a completely different one, by natural or supernatural means. Gregor Samsa led an ordinary and rather mundane life as a traveling salesman who spent the majority of his time on the road with little time to form friendships or relationship with anyone outside of his small family. Once filled with gratitude by providing for his family, he is soon filled with resentment and obligation as his family adjusts to their newfound income. All of which comes to a halt when Gregor wakes up late to work and is horrified by the sight of his new appearance with countless sets of legs and a hard-shell-like exterior. His family soon finds out about his physical

The Metamorphosis, by Franz Kafka, tells a unique story about a young man that suddenly turns into a bug; Gregor Samsa. The reason for Gregor turning into a cockroach unexplained. The novel is told as if Gregor; the main character, is perfectly normal. Kafka portrays Gregor as a very selfless man, not thinking of his own health or what would be good for him. Throughout the book there are many Gregor is seemingly cut off from the world, the transformation into a bug almost like a metaphor for Gregor's own life.

From this lab, it can be concluded that planarians will regenerate no matter how they were cut. Wormy and Wormy 2.0, were both trisected transversely and were thought to grow into six new planarians, three coming from each worm, and one of them possessing two heads. The results observed for Wormy fully supported the hypothesis, and the three new planarians had a head, midsection, and tail. However, Wormy 2.0’s hypothesis was not supported by the results at all. For one, the hypothesis and results for the tail part were incomparable due to the fact it was missing, and the prediction for the body, or middle part was quite absurd. Through further research, it is possible to have a planarian with two heads, but a longitudinal cut would have to be used instead of a transversal cut.

The Earthworm, starfish, frog, fetal pig, and human all have much in common; however, some have more in common than others. Many have a matching digestive system but not a matching skeletal or circulatory system. Thought numerous dissections we can compare and contrast the various animal systems and gain knowledge on more than just the external side of an animal.

Cell proliferation in planarians carried out through the formation of the blastema regeneration and proliferating, having to require steps, mitosis and migration, to active area of planarian regeneration. Interactions between pre-existing and regenerated tissues distinguish the positional identities of tissues due to the origin of influence. Not all planarian species display morphallaxis pattern therefore not all triclad planarians such as, free-living flatworms with the characteristics of having three branches. D. lugubris species display relationship between pre-existing tissues and the blastema, forming new structures or having old structure be remodeled within pre-existing tissue. Studying planarians have hinted that organ system and cell type regulation that occur are produce d in proper proportions, developing the result defining that proportion of specific tissues in planarians models and their cell numbers correspond to each

The following section was entitled “What Does Developement Tell Us,” and in it, Jeffery described the developmental phases of Astyanax because “evolutionary changes proceed through alterations in development.” By describing the different phases, Jeffery was able to point out the places where the development of the eyes in cavefish morphologies is different from the surface-dwelling fish. The first phase of eye development in both forms of the Astyanax is the appearance of optic vesicles, and with this appearance and other simultaneous mechanisms, the eye primordia, consisting of the lens vesicle, an optic cup with an inner retinal layer and an outer retinal pigment epithelium layer, and optic stalk, forms. I found it extremely important

Almost all life-forms were unicellular after the origin of life. Small multicellular algae are exceptions. In a comparatively short period of time, critters with exoskeletons,

As a young undergraduate, I knew just enough about bivalves and brachiopods to explain their differences and similarities to an elementary schooler. Although both of these groups looked like clams, one subtle distinguishing characteristic I could call upon was their symmetry. If you were to split a bivalve in two, you would have two nearly-identical valves--bivalves had symmetrical valves. Such could not be said for brachiopods, for they had a distinct upper and lower valve. Brachiopods, by contrast, were symmetrical across their midline.

Metazoans are most likely a clade, that is, they all descended from one kind of protist. All metazoans originally had one cilium or flagellum per cell, for example. Metazoans also share the same kind of early development. They form into infolded balls of internal cells which are often free to move, and are covered by outer sheets of cells that form an external coating for the animal: a skin, if you like.
