Typing this paper, although optional, is encouraged. Your answers will be graded based on length, completeness of information and quality. This assignment will count as test grade. 1) Identify a food chain consisting of organisms in the movie. Include at least 4 organisms and be sure to identify which organisms are the producers, first level, secondary level, and tertiary level consumers.
Frog Defence Mechanisms Research into several frog species has produced evidence that although frog’s possess the same general characteristics, many different species have developed their own unique methods of defence and escaping predation. Some species of frog have discovered that one of the best forms of defence is simply to hide. Many frogs have developed a great number of different disguises to escape the sight of potential predators. For example the Mossy frog (Rana septentrionalis- Fig. 2.7) – is covered in small bumps and spines, (Raxworthy, 2007), which along with it’s brown/green colouration allows it to blend perfectly into it’s mossy surroundings.
FREAKS OF NATURE: THE WATER HOLDING FROG This video documentary was done by the National Geographic Channel on November 15, 2011 entitled: Freaks of Nature the Water Holding Frog. It began by asking the question of what is the one thing that all living creatures need the most on earth. The answer to that is water. In this video we get to see the Litoria Platycephala. It is a species of frog that is found in the northern region of Australia.
Comparative embryology B. The embryos of each of the following vertebrate Chordates, chicken( bird), human (mammal), mouse (mammal), turtle (reptile) and frog (amphibian) have the following three structures during their embryological development, a tail, pharyngeal gill arches and a notochord. None of these three structures persist in the adult forms. Thus the taxonomic basis for where these five organisms fit unites them into one phylum with characteristics that only persist in the embryonic development, not in the adults. C. The three characteristics mentioned above are key characteristics that are found in all Chordates, but in the above five examples, the characteristics are found only in the embryonic stages.
What makes humans so distinct? Introduction When brainstorming the term human one the first associations that might come to one’s mind are walking, talking, creativity, reasoning and war. A more sophisticated definition taken from the dictionary suggests that within a biological system the human is considered eutherian and belongs to the family of primates. The modern human, also Homo sapiens, is the only remaining species of the genus Homo. When compared with other animals it is especially the complexity of the human brain, capable of language, problem-solving, introspection and abstract reasoning, as well as the upright posture that stand out.
These measurements will be used to calculate the skull’s supraorbital height according to the formula: (BC/AC) × 100 = Supraorbital Height 4. Record the skull’s supraorbital height in the data table. 5. Take the same measurements for each of the skulls, recording the supraorbital heights in the data table. Data and Observations: Create a data table to record your observations and measurements for each skull: Skull|Forehead|Face|Teeth|Foramen Magnum|Brain Cavity |Supraorbital Height (cm)| Pan troglodytes (modern chimpanzee)|Sloping|Flattened|Short/Dull|Rear|6.08cm|54.934cm| Homo sapiens(modern human)|Vertical|Flattened|Short/Dull|Front|9.01cm|67.703cm| Homo erectus(extinct hominid)|Vertical|Vertical|Short/Dull|Front|6.69cm|61.883cm| Australopithecus afarensis (extinct hominid)|Sloping |Vertical|Both/Both|Rear|5.92cm|53.209cm| Unidentified Fossil Skull |Sloping |Flattened|Short/Dull|Rear|6.60cm|51.364cm| Conclusion: I think that the unknown skull holds the most similarities to pan troglodytes.
It works efficiently in larger databases. It takes only the sample datum from the dataset instead of full dataset [17].It selects the data from the set and finds medoids for finding the outlier. The dataset D is taken as input and the sample data is taken as S where the PAM concept is applied to CLARA to find the medoid M. After finding the medoid the entire dataset D is classified based on cost then the average is calculated to find the dissimilarities between the clusters. CLARA Pseudo code 5.3 LOCAL OUTLIER FACTOR This algorithm is proposed by Markus M. Breunig, Hans-Peter Kriegel [18], Raymond T. Ng and Jorg Sander in 2000 for finding anomalous data points by measuring the local deviation of a given data point with respect to its neighbors [18]. Higher amounts of data are collected and they are stored in databases by increasing the need of the data for efficient and effective analysis methods to make use of the information contained implicitly in the data [18].LOF is found to the every data in the dataset to indicate the degree of outlierness.
Title The Double Life of the Frog Introduction Although the frog is a common animal in many parts of the country, scientists note it’s rather uncommon to life cycle. The word “amphibian,” generally used to characterize frogs, literally means “having two lives,” although, of course, the frog lives only once. Thesis statement But that one life is divided into two separate distinct phases, the first one of which is with two subtopics spent underwater and the second, primarily on land. Body During the initial stage of a frog’s life, it is not really a frog at all, but rather a tadpole paragraph 1 or pollywog. When such a tadpole hatches from an underwear jellylike mass of eggs, it (develops very much resembles a fish in outward appearance, with a vertical tail and with gills on subtopic 1) sides of its little head.

For example, Gunjan Sinja states that scientist Garth Nicolson, chairman of tumor biology at the University of Texas M.D. Anderson Cancer Center in Houston, defines the syndrome as Mycoplasma fermentans. Sinha also stated that Mycoplasma fermentan was "the most poorly studied bug on the list (Sinha 70). '; Nicolson has found that the M. fermentans is nested inside the cells of almost half of all cases. Sinha defines Mycoplasmas as "the smallest self-replicating life form that latch onto white bloodcells, which are part of the body's disease defenses, with a hooklike tip; then they transmit chemical signal that force blood cells to behave abnormally (Sinha 70).
