Craniata Essay

Accompanied by fossil experts Fred Mullison and Bob Masek, the author discovered a fish with a wrist, and another with a part of a fin, and part of a limb. They worked to relate the structure of the fin/wrist joint with its function for the fish. Titaalik had shoulder, elbow, and wrist shapes composed of the same bones as the upper arm, forearm, and wrist in humans. With pectoral muscle scars and crests, the author could conclude that the fish could do “pushups”. Considering the rest of the animal, with its flat head, top eyes, and ribs, the fish was built to navigate the bottom of streams and ponds, avoiding larger predators in the water. The interesting hypothesis coming from this evidence is that many of the major bones humans use to do different functions such as walk, throw, and grasp came first from other ancient animals. Yet, these bones similar in structure to their ancient counterparts come together to create a unique construction in the present. Characteristic of this construction include our ability to rotate our thumbs relative to the elbow, leading to hand usage, as well as the hind limbs with knees and elbows in opposite directions, leading to bipedal

Crayfish (Procambarus clarkii) are crustaceans that are similarly related to crabs, lobsters and shrimps. They live in partly salty water (brackish water), rivers, ponds and are considered omnivores because they feed on small fishes, plants, detritus, mollusk, and other small invertebrates. Crayfish have a hard-calcified exoskeleton which is typically made of structural polysaccharide called chitin. This calcified exoskeleton must shed for the crayfish to grow (Fitzgerald, 2006).

Patient safety and hospital acquired infections (HAI) are deemed highly important in the health care setting. My organization uses quality indicators pulled from EPIC, which is our health information system, to ensure we are meeting regulations for catheter associated urinary tract infections (CAUTI). Data includes rates of infections, length of foley catheter placement, reasons for foley placement, as well as facility specific documentation that is used to aide in the prevention of CAUTI. By pulling this data, one could identify trends affecting rate of infections. This may lead to a change in policy or procedure that can improve the rate of infections for those patients with foley catheters. Thus decreasing the percentage of HAI’s for

These two features earlier are examples that we can see with our naked eyes, but the DNA make up that we cannot see with our eyes alone are also laid out the same as well. In the evolutionary pathway, the genes that turn on and off for humans and fish are related through the instructions on how they function. All living things with limbs have in common the Sonic hedgehog gene (Shubin, p. 53). The Sonic hedgehog gene can control the development of the limbs in these creatures. To determine if the development of vertebrate animals can be interpreted in the same way, or have the same effect, the injection of vitamin A was used to inject into a shark, mice, and chicken embryos to see if the results were the same. The results turned out that the injection of vitamin A has indeed changed the development of limbs in these embryos. The effects cause the shark to have a mirror image of its fin, and the mice and chicken have duplication of bones in the limbs (Shubin, p.56-57). It becomes clear of what will happen if

Catheter related bloodstream infections are not only responsible for prolonged hospital stays and increased hospital costs, it is also responsible for increased mortality of the hospitalized patients. According to Centers for Disease Control and Prevention (2017), an estimate of 30,100 central line-associated bloodstream infections (CLABSI) occur in intensive care units and wards of U.S. acute care facilities each year. CLABSI is a serious hospital-acquired infection that occurs when bacteria enters the bloodstream through central venous catheters. CLABSI is preventable as long as health-care personnel practice aseptic techniques when working with the catheter. A blood culture swabbed from the tip of the catheter is needed to confirm the

Lives in freshwater swamps and marshes, and also in rivers and lakes. They can tolerate a little bit of salt but prefer fresh water. They can tolerate freezing weather for short periods of time but are better off in warmer weather. To live better in this weather, the alligator builds burrows to hide from the weather.

Congresswoman Suzanne Bonamici was elected in 2012 to represent Oregon’s first district, which is located Northwest of the state. Bonamici is currently on two committees which are Education and Workforce and Science, Space and Technology. Her main priority as Congresswoman is to advocate for federal policies that can benefit working families a chance to succeed in the economy. Bonamici has been a big advocate in not only helping workers to become financially secure but also saving up for their retirement. Congresswoman Suzanne has been a strong supporter of raising the federal minimum wage, giving workers the opportunity to voice their opinion in their jobs, paid family leave and giving women the opportunity to have access to family

Illiana Cardona,105, of Blackfoot, Idaho, recently passed away on November 24, 2105. She passed peacefully in her sleep after finishing her extensive research essay that held the answer to cure all known and unknown diseases. “She was a real fighter as well as stubborn,” Avenir “Ave” Mari told reporters after announcing his wife’s death,” It took me years to convince her to marry me.”

The Emergency Medical Treatment and Active Labor Act (EMTALA) was enacted in 1986 as a part of the Consolidated Omnibus Budget Reconciliation Act (COBRA) of 1985. EMTALA was enacted to prevent hospitals with Emergency Departments from refusing to treat or transferring patients with emergency medical conditions (EMC) due to an inability to pay for their services. This act also applies to satellite locations whom advertise titles such as “Immediate Care” or “Urgent Care,” and all other facilities where one-third of their patient intake are walk-ins. Several rules and regulations to this act have been established and it has become a very serious piece of legislation and health

Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and

     The madrigal is a distinctive type of secular song that originated in Italy. It was an aristocratic form of poetry and music that flourished at small Italian courts. In the piece, Cruda Amarilli, Monteverdi uses many musical devices that are typical of a madrigal. The lyrics in this song are repeated, the music accompanies the text in interesting ways, and there is a wide range of vocal notes. After listening to the piece just once you can immediately feel the unrequited love Monteverdi is displaying through his words and music. The music and instrumentation in this piece aid the voices to establish form and mood through word painting. He uses word painting and cadences to develop a theme of unrequited love.

El Greco (“The Greek”), also known as Domenicos Theotocopulos, was a painter, sculptor, and architect of the Spanish Renaissance. El Greco was born in Crete in 1541, which was then a part of the Republic of Venice, and the center of Post-Byzantine art. He had trained and become a master within that tradition and an icon painter. Among his great artworks, I would like to draw attention to “Pietà (The Lamentation of Christ)”, an oil painting. El Greco had painted this masterpiece about c.1565-70 in Italy, during the Cretan period.

Most biologists regard this taxon as extinct, but the name is sometimes used in the classification of lampreys, because lampreys were once thought to be related to cephalaspids. If lampreys are included, they would extend the known range of the group from the Silurian and Devonian periods to the present day.

In order for a character to qualify as the tragic hero they must posses all of these qualities: high standing, a major flaw, and a downfall. A tragic hero is someone that is usually of royalty, of nobility, honest, or brave. During the story they usually show a major flaw or weakness. This usually leads to their downfall, loss of power, or even death. Many stories have tragic heroes.

It is tempting to suppose that the influence of Parker’s Hora Novissima must have strongly influenced Ives’ first attempt at a major choral work; after all, the famous Parker was his teacher, and it is common for students to follow in the footsteps of their mentors. But even a cursory examination of textural and harmonic aspects of Hora Novissima reveals a scale and complexity that makes comparison with the more straight-forward The Celestial Country of questionable value. Hora Novissima calls for soloists SATB, chorus SATB, full orchestra, and organ. Sherwood reports that a 1894 Boston performance by the Handel and Haydn Society fielded a chorus of 383 singers and an orchestra of 57. The forces assembled by Ives for the Friday, April
