Urchin

The sea urchin was both a clone and a refutation of a then-current theory. The actual cloning process was not publicized until the 1990s when Dolly the sheep was cloned. Dolly the sheep became famous because she was the first animal to be cloned from an adult somatic…

Darwin once stated that coral reefs “rank high amongst the wonderful objects in the world”. Reefs are amazing, they are animal, they are plant, they sometimes appear dead, and they sometimes are brimming with precious life. Reefs are rainforests, filled with so much life and beauty. “It is estimated that at least half a million and possibly as many as nine million species spend part of their lives on coral reefs” (“The Sixth Extinction”, Kolbert). This chapter sadly tells us that these…

and they are around 80 cm in diameter. The colours can vary giving the seastar a beautiful appearance. They range from reddish-orange to yellow, violet brown, or slatey purple (Aherne and Benhnke, 1991). They are predatory,usually feeding on sea urchins, snails, clams, and other small organisms. The sunflower seastar inhabits low sub tidal and intertidal areas with an abundance of seaweed or kelp (Esquivel, 2003). This particular sea star can move more rapidly because it possesses a very…

shrimp. We also participated in some activities. They included a live broadcast from a filming room to the TV outside, creating electricity through bicycles, seeing which lightbulbs took the least energy, petting anemones, sea cucumbers, and sea urchins, and redirecting water flow to sail little boats on. During this trip, we came upon many international issues, such as carbon dioxide (CO2) in the oceans, causing the acidity to rise. Another was human energy consumption, and how it pollutes.…

present, the more acidic the water will be. How does Ocean Acidification impact the Earth? The ocean’s make up most of the world’s biodiversity, provide humans with food, and maintain numerous food webs. Coral reefs, mollusks, plankton, and sea urchins utilize carbonate ions and calcium to make their shells. However, the presence of hydrogen ions erodes shells and decreases the amount of carbonate present. As a result, this deteriorates coral reefs quicker than they can replenish themselves.…

Cloning is nothing new. Organisms are considered clones when their entire DNA is identical. Clones are able to happen naturally as is the example of biological twins or they can be made in a lab through modern technologies. The three types of cloning that currently exist are: reproductive cloning, gene cloning, and therapeutic cloning. Cloning an organism is different from cloning a gene. The process of cloning an organism involves making an exact genetic copy of the whole thing rather than…

presentation that without keystone species many of the animals in the ecosystem would have to adapt to their environment differently. In my presentation I studied Killer Whales. Killer Whales controlled over many animals like fish, seals, and sea urchins all the way down to kelp. Going closer into one of the animals it controls various species of fish and sea lions. Without the killer whale which controls the population of the sea lions there wouldn’t be enough fish. This would be true because…

Thank you, Begleiter, for the Exclamation Point in Oliver! Lionel Begleiter wrote and composed a 1960 stage musical inspired by the Charles Dickens’s book Oliver Twist; this was eventually released in 1968 as a film musical (Oliver! Background). Under director Sir Carol Reed’s supervision, an unlikely selection for directing this heartfelt film based on his previous works of war movies as of The Third Man and the Hitchcock-styled Night Train to Munich; Oliver! became a sensation for its time…

Food is a necessity for all human beings. Food can come in big sizes, medium sizes, and small sizes. A person may eat food if they are hungry, if they are experiencing an ungrateful situation, or even if they just want to taste the deliciousness of food. However, not many people realize the symbolic meaning of food in a way that Elie Wiesel and Frederick Douglass realizes. Elie Wiesel and Frederick Douglass both uses food in their story to convey a deeper meaning of life. Elie Wiesel and…

He forms a team with a not-so-popular fraternity and they join the annual Scare Games. The Scare Games is an event where monsters are pitted against each other to compete in challenges ranging from running through tunnels filled with poisonous sea urchin like objects to a giant scaring simulator where the monsters scare a fake child in order to get the highest score. One of Mike’s teammates rigs the simulator so the fake kid can scare easily which allows Mike to not embarrass himself in front…
