This body cavity has given this phylum its other, less commonly used, name of Coelenterata. Cnidarians have a complex life cycle that, depending on the species, may alternate between two forms. The first form is known as a polyp, which is sessile (anchored to one spot). The polyps are tubular in shape, with the mouth, often lined with tentacles, facing upwards. The bodies often con...
In Mazzucchelli’s Asterios Polyp, he illustrates different characters with how that character perceives the world, and how they regard others. The fourth chapter’s bookmark shows sixteen different ways of illustrating a single apple, representing different artistic styles that you see in the novel. All the drawings are of the same apple, but each one has its own unique style. On the next page, the same representations are illustrated, only the depictions are of students instead of apples.

Colon cancer is the third most common cancer in men and women, responsible for more than 57,000 deaths in 2001 alone. Colon polyps, which can lead to colon cancer, are found in about 30-40% of people aged 60 or older- and the risks of polyps increase with age” (Lerche Davis, 2003). Most cases of colon cancer start as small adenomatous polyps. Many people experience no signs or symptoms in the early stages of colon cancer. Some signs and symptoms can include diarrhea, constipation
in a hemorrhage of the vocal lining, called a hemorrhagic polyp. The edge in her style of singing is the likely contribution to the polyp, along with a combination of smoking (WebMD). In October, 2011Adele underwent surgery to treat the vocal fold polyp with hemorrhage (Fauquier ENT). For this study I will use her case to study the effects of a laryngeal growth on the voice. WHAT IS A VOCAL FOLD POLYP AND HEMORRHAGE? Vocal fold polyps are a benign (non-cancerous) growth on either on one or both
reefs. (Grigs, 1997). Corals are made up of tiny cup-shaped animals called polyps, which are similar to jellyfish. They begin life in tropical waters as free-floating larvae but eventually settle on the ocean bottom and form large, sedentary colonies. A single polyp may eventually become as large as a saucer or stay as small as the head of a pin. All polyps start off small and some single polyps become large. Billions of polyps working together, generation after generation, creat... ... middle of
colon or rectum. These changes might be dysplasia or adenomatous polyps. A polyp is a growth of tissue into the center of the colon or rectum. Some types of polyps (hyperplastic polyps and inflammatory polyps) are not precancerous. However, having adenomatous polyps, also known as adenomas, does increase a person’s risk of developing cancer, especially if there are many polyps or they are large. In contrast to the inward growth of a polyp, a true cancer can grow inward toward the hollow part of the colon
What is cancer? Cancer is when abnormal cells divide in an uncontrolled way in a part of the body. Cancer can start in any place of the body. Cancers are typically named for the organ or the cell where the cancer begins. Some cancers can spread from the original site and move to other places in the body.If the spread of cancer is not controlled it may result in death.Cancer develops when the body’s normal control mechanism stops working. Old cells do not bite the dust and these cells grow out of
communities of tiny jellyfish like polyps. These polyps absorb calcium from the sea water and secrete a hard limestone skeleton. At night the polyps extend sticky, stinging tentacles from their skeletons to capture and consume small floating organisms such as zooplankton. Every coral has a two-stage life cycle: the larva, and the polyp. The larval stage is free swimming, and the polyp is stationary. Ocean currents carry the larva from the stationary parent polyp to any hard, clean, silt-free surface
coral reefs.). (end of part 4) Oceanographers and scientist are still finding out how to save the coral reefs but they already have some theories that might help save the reefs like; improve water quality (high water temperature can kill coral polyps and coral.), create awareness around the world, more nature conservatives (protect reefs from fishers and nets). Some of the practical ways are to use less water (less water = less pollution, less water waste.), drive less (fossil fuels can end up
a class of diseases characterized by uncontrollable cell growth. Colon cancer forms when cells in the large intestine grow uncontrollably. Most colon cancers come from small, benign tumors known as adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps can grow and become malignant colon cancers over time if they are not removed during a colonoscopy. Colon cancer cells will invade and hurt healthy tissues that are near the tumor creating a lot of problems. After
a mariner its important to know about the marine life, that was one reason I have chosen this topic for my today’s short presentation. GM, my scheme of presentation will be as flashed: DEFINATION OF CORAL REEF DIFFERENCE BETWEEN CORAL AND CORAL POLYP WHERE WE CAN FIND CORAL CONSTRUCTION OF CORAL REEFS CONDITIONS FOR GROWTH OF CORAL REEFS TYPES OF CORAL REEFS THREAT TO CROAL REEFS WHAT SHOULD A MARINER DO IN CORAL RICH AREAS FUTURE OF CORAL REEFS CONCLUSION What is a coral reef? Coral reefs are

Simply a form of cancer which originates in the colon or rectum. It starts with the presence of what is known as a polyp which is a growth on the walls of the rectal region. In time this growth continues to
dying because of this cancer. Colon cancer is also known as Colorectal cancer, this process occurs in the rectum/colon area. It starts in the large intestine, the lower part of your digestive system. Most of colon cancers develop first as colorectal polyps, which are abnormal growths inside the colon that can maybe turn cancerous. Colon Cancer is also one of the most typical inherited cancer syndromes known. This means that its been passed down in several generations of a family. There are several gene
are reef building hard coral. Reefs are actually limestone structures produced by small animals called coral polyps. These polyps contain unicellular plants (algae) called zooxanthellae in their tissue. They have a symbiotic relationship which means, "living together." During the day the zooxanthellae rise to the surface of the animal and produce food by photosynthesis. At night the polyp extends a stinging, multitenticled mouth that feeds on any planktonic animals. They both benefit from the waste
How could your gut bacteria cause you colon cancer? According to the article, “Gut Microbes Combine to cause Colon Cancer, Study Suggests” They reported that there is two type of bacteria causing colon cancer according to recent research publications. There are two type of bacteria associated with colon cancer Bacteroides fragilis and E. coli, they are known to produce a layer in the intestine lining. According to this article, E. coli have toxin that can damage DNA of the colon cells. Additionally
Peutz-Jeghers Syndrome (PJS) is an autosomal-dominant inheritance condition that usually runs in families. Another name for this disorder is hereditary intestinal polyposis syndrome. PJS is a rare disorder and occurs in 1 in 160,000 to 1 in 280,000 persons. Peutz- Jeghers Syndrome is “caused by a change (mutation) in a gene that increases the risk for developing colon and other cancers. There are two common types of Peutz-Jeghers Syndrome. There is familial PJS and sporadic PJS. Familial PJS is
farther offshore, with a channel or lagoon between it and the shore. The outer layer of a reef consists of living animals, or polyps, of coral. Single-celled algae called zooxanthellae live within the coral polyps, and a skeleton containing filamentous green algae surrounds them. The photosynthetic zooxanthellae and green algae transfer food energy directly to the coral polyps, while acquiring scarce nutrients from the coral. The numerous micro habitats of coral reefs and the high biological productivity
or soft. According to reefed.edu, soft corals are “soft bodies made up of a large number of polyps connected by a fleshy tissue.” Meanwhile, hard, or “stony,” corals consist of a solid, limestone skeleton. Hard and soft coral can also be easily distinguished by the number of tentacles a coral has. Soft corals have eight tentacles on each polyp, while hard corals have multiples of six tentacles per polyp (ReefED, “Hard Corals”). Hard corals are also able to come together to form the basis of coral
digest and absorb nutrients from food, concentrate fecal material by absorbing fluid from it and retaining waste products until elimination (Colorectal). Sometimes abnormal growths, called polyps, form in the colon or rectum. When the polyps first form, they are not cancerous. Over time, however, some of these polyps may become cancerous (Colon Cancer). Colorectal cancer is usually identified through screening in its early stages. Unfortunately, many patients are not diagnosed until they notice the
that will pertain to the scientific order Alcyonacea, or all types of soft corals. What are soft corals? Soft corals are grouped in the phylum Cnidaria, class Anthozoa, and order Alcyonacea. Their distinguishing characteristic is that their polyps always bear eight tentacles which are on both edges fringed by rows of pinnules (Fabricius and De’ath, 2002). The common name “soft coral” comes from the fact that they have no massive external skeleton as compared to the more commonly studied hard
