Planarian

1. I believe we were asked to find the paper using the citation provided rather than having a copy of the paper posted on the D2L website in order to familiarize ourselves with how to interpret citations, since it is critical to understand what information (for example: title, author, publishing date) is provided within the citation, and also to get a sense of how the Ryerson online library site operates, along with the various resources offered on the library site. 2. The legal reason as to…

kingdoms. However, Hydra appears to have whiskers with the similar ladder-like scale structure as those on a shrimp. Also, the name Hydra hints that it would have aquatic relations. In this case the Hydra can be best labelled as an animal. Now, the Planarian seems to have two eyes, a membrane bound organelle in its centre, and many small vein-like structures condensed throughout its body. With this information, it is most likely that Planaria is multicellular, and with with evidence of eyes we…

Most animals have diverse digestive tracts, which are modified according to the means of obtaining food and diet of the animal, but they all perform a set of functions needed to provide nutrition. For example, hydras, planarians, and earthworms have a digestive tubular tract where one end of the tube is the entrance for food and the other end is the exit for waste; other more complex animals have to go through several stomach compartments, ruminants, as their food digests…

Coral reefs are Anthozoans. Scientists classify them as animals. They are the largest class of organisms in the phylum cnidarian. There are more than six thousand species. Coral reefs are communities of living things. They are known as the “rainforests of the oceans.” This is because there are sea slugs, oysters and many other creatures living there. Corals are animals related to anemones and jellyfish. They extend their tentacles to sting. A polyp is an individual coral consisting of a stomach…

Symbiosis is the interaction between two different organisms in an environment and the effect they may have on each other, if any. When observed in nature, these encounters can illustrate the complex relationship among organisms and how their survival is directly affected. Neutralism, for instance, is a relationship in which neither of the interacting symbionts benefit nor suffer. Mutualism, on the other hand, is a relationship in which both symbionts are physiologically dependent on one another…

With Page’s goal of dramatically extending human life, curing cancer seems to fall into this Google X equation. Though Page stated immortality is not a goal, this is nothing less than what kings and alchemy sought in the past. Seems that Planarian worms and their telomeres (energy carriers within chromosomes, which serve as a protective cap) hold the key to immortality and has been deemed to be a journey worth researching. With the forward progression of advanced information and bio-tech…

Wednesday Journal: Today, we spent our time at the Audubon Center of the Northwoods in Sandstone, Minnesota. The weather was sunny with splashes of clouds and it felt especially humid. The first part of the day was spent contrasting the prairies we observed yesterday at Sherburne Wildlife Refuge with the newly restored prairie at Audubon. Historically, the new prairie was an old agricultural field; the team removed the old plants, sprayed to remove the plants, burned off the older vegetation…
