Starfish regenerate limbs by when one of their limbs is torn apart. Its reason are for protection as a well as reproduction. When the limb that was torn apart it heals. It begins to reproduce new cells which regrows a new limbs. It takes about a year or couple months to grow back. Sometimes there will be a defect on the growth of the new limbs. One of the defects are growing an extra limbs.
The main idea of this story Fish Cheeks was understanding and appreciation and having pride in one own unique culture. Tan mother invites the minsters family who happens to be her crush at the time who is Robert the minister’s son. Tan felt despaired during the entire evening, feeling ashamed of her family and non- American ways at dinner. At the end of the evening Tan’s mother tells her that she understands that she wants to like all the other American girls and handed a gift. Tan’s mother points out to her that she must not be ashamed of her difference, however, embrace these differences that she has found shame in. Overall the main idea was the differences that we are often ashamed of are the differences we should take pride in, because
In 1962, at 11:00:09 pm local time on July 8th, the United States detonated a thermonuclear warhead riding atop a Thor missile at 400 km above Johnston Island at a distance of 826 miles from Honolulu, Hawaii. That night was one that many on the Hawaii Islands would never forget (Berkhouse, 1962). Operation , as the test was code named by the U.S. military, caused the first damage in the United States from an electromagnetic pulse created by a nuclear detonation. Though the damage was not intended or planned, the 1.4-megaton weapon caused “the failure of street-lighting systems, tripping of circuit breakers, triggering of burglar alarms, and damage to a telecommunications relay facility.” (EMP Commission, 2004, p. 4)
...ograft. If the graft comes from someone who has died, it is called an allograft. Doctors have tried using some types of synthetic grafts but so far these have not worked well. Research is being done to see if there are better types of grafts that can be used.
Understanding other people’s perspective is vital when it comes to making someone a more informed and a more sympathetic person. For example, in politics, there are two main sides; the democrats and the republicans. These two sides almost never see eye to eye, but when they see from the other’s point of view, an agreement can be made.
So far, various techniques have been used for reconstruction and regeneration of maxillary and mandibular bone defects. Autogenous bone grafting, guided bone regeneration (GBR), distraction osteogenesis and nerve transpositioning are among these regenerative techniques (1-8). Decision making for the treatment could be influenced by the type, size and location of the bone defects (2, 3, 9, 10). GBR had high success rate in treating small alveolar defects such as dehiscence or fenestration. Regenerative bony walls around the defect with ingrowing blood vessels can begin osteogenesis (11) larger bone defects with insufficient regenerative walls and an low quality avascular bed need varied amount of autogeneous bone graft from extra oral or intra oral donor sites, however, the patient may suffer from complications in donor site as well as bone graft resorption.(10, 12-15)
Goldfish, like other cold-blooded animals, have pigment cells that are called chromatophores. Inside chromatophores are chromatosomes, which are the organelles which hold the pigment. The chromatosomes can absorb or reflect light. The color of a fish is dictated by what kinds of chromatosomes are in its cells, how many chromatosomes there are, and where in the cell the chromatosomes are located; these, in sum, control which chromatosomes absorb light and which ones reflect it, therefore affecting what color we see when we look at the fish. Chromatophores can change color in two ways: by the chromatosomes spreading apart inside the cells, making the color more apparent to the eye; or by the chromatosomes changing color, prompting a visual difference in color throughout the entire organism.
Although nothing can ever fully replace any part of our bodies, most people who have suffered the loss of a body part or who were born missing something that everyone else has and needs—like a foot or a hand—would agree that something is usually better than nothing. People have used all sorts of artificial devices probably from the beginnings of human history to help them compensate for the loss of a limb. Thus in very ancient times, the first and simplest prosthesis may have been a forked tree limb that was used as a crutch to help someone walk whose leg may have been badly damaged or lost in an accident or to a disease.
Stem cells have the ability to transform into any kind of cell. These cells can divide and also replenish other cells in the body, such as muscle cells, brain cells, red blood cells, or they may just simply remain as stem cells. Stem cells are able to replicate even after long periods of dormancy. They naturally repair damaged tissues and can be experimentally induced to work with particular tissues and organs (NIH, 2013).

In the popular British Television Series, Doctor Who, an interesting theory was invented and proposed, the theory of Regeneration. The Doctor, who is the main character in Doctor Who, is a Time Lord. The Time Lords are a race of technologically advanced aliens from Gallifrey who possess two hearts and the ability to, you guessed it, regenerate. This ability allows the Doctor to be reborn every time he dies up to twelve times, except in the case of The Doctor who apparently can regenerate many more times now. The question becomes, what is regeneration and how is it possible? In this paper I am going to put forth my own theory on the Doctor’s regeneration and answer some of the objections that have been proposed against it. My theory of regeneration includes some simple Organic Chemistry, specifically the theory of Stereoisomerism, which I will try to explain here, so as the Doctor would say Allons-y!
About half of the fish species live in groups at some point in their life
The theme of The Arm of the Starfish is that it can be challenging to make decisions. In the novel, Adam Eddington finds himself caught in a power struggle between groups who both attempt to recruit him to their side. Eventually Adam must make an important decision and determine which side he supports. The Arm of the Starfish is a novel about Adam Eddington who travels to Lisbon for his marine biology internship with Dr. O’Keefe. On the way to Lisbon, he is alerted that Dr. O’Keefe is untrustworthy by Carolyn Cutter, but after meeting some of O’Keefe’s colleagues he determines that Carolyn may be dishonest. Adam works with O’Keefe on his top-secret experiment featuring limb regeneration, and learns that if the results of the experiment reach the wrong hands it could be catastrophic. Eventually Adam must secretly deliver the papers to the
In the stories “The Metamorphosis” by Franz Kafka and “What, of This Goldfish, Would You Wish” by Etgar Keret, the main conflicts are centered around the magical realism present in each story. In ”The Metamorphosis” a traveling salesman named Gregor is transformed into some kind of vermin and thus starts the main conflict of Gregor’s constant ostracization by his family after he’s unable to assist him anymore and slowly becomes consumed by loneliness. In “What, of This Goldfish, Would You Wish” a man named Sergei is visited by a young boy who is making a special for TV about what you would wish of a magic goldfish Sergei having no interest turns him down but finds the kid in his house screaming about his goldfish this alarming Sergei he hit
Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
A number of organs have the intrinsic ability to regenerate, a distinctive feature that varies among organisms. Organ regeneration is a process not fully yet understood however when its underlyning mechanism are unreveled, it holds tremendous therapeutic potential for humans. [28]
