Once you tour the pond water, choose your favorite organism and describe the following for this organism. Detailed cell structure of the organism (Include locomotive structures, composition of cell wall and any special organelles) Nutrition of the organism Classification Importance in the food chain and pond ecosystem. Question 2: Describe in detail the cell wall structure of Gram-positive, Gram-Negative and Mycobacterial species. Highlight the molecules that make up each cell wall and how these molecules play a role in the classification of these bacteria. Question 3: Case Study from Chapter 12 Matt was not in good shape and it had nothing to with the time spent at the gym. It had to do with the ball of fungus in his right lung. That fungal sphere, Aspergilloma had started as a single spore of ascomycete fungus called Aspergillus. The mold had formed the mass of fungal hyphae that was invading the airways of his lung and slowly killing him. Such bronchopulmonary Aspergillus is a rare but increasingly frequent pathogen of the immunocompromised. Besides experiencing difficulty in breathing, fever and chest pain, Matt most hated coughing up wads of bloody mucous. His disease had invaded his blood and was now progressing to his brain. Soon it might lead to paralysis. Matt spent 4 weeks at the hospital and thankfully a new antifungal drug, Voriconazole brought Matt back to life. How could a microbiologist determine that the fungus infecting Matt is an Aspergillus not any other fungus? Through research look up how antifungal drugs work and explain how the drug might have neutralized the fungal hyphae. Your answers should be detailed and you will be graded on the quality and quantity of your answers. Please provide a minimum of 3 citations in your assignment. All scientific journals need to be cited in the APA format. Link for Pond Water tour below http://vsprotista.weebly.com/virtual-lab.html

By itself, a virus cannot reproduce, grow and develop, respond to stimuli, take in material and energy from the environment, nor show any adaptation. However, it is organized with a protein coat that surrounds hereditary material and once inside another living cell the virus takes over the host’s metabolic machinery in order to grow, develop, and reproduce new virus particles. Therefore, is the virus a living or dead organism?  Explain your answer.

You may write the question and number in your document. Under the question, document your response. Please be detailed and specific in your responses to fully address each question. PLEASE NOTE: It’s recommended that you use your textbook. All answers can be located in your textbook. If outside websites are used, please summarize the information in your own words and provide APA style citations. Plagiarism Warning: Copying and pasting information from outside sources is considered plagiarism and is a violation Academic Honesty. All submissions are checked for plagiarism and will receive a grade of 1%. Only sentence-long direct quotes (properly cited in APA) are permitted. For this essay , answer the following questions in one to two short paragraphs each. 1.Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. 2.Compare and contrast the traits and growth patterns of opportunistic versus equilibrium populations. Provide one example of each. 3.Compare and contrast indirect versus direct values of biodiversity, and provide examples. 4.Describe two traits that represent a sustainable society and two traits of a nonsustainable society.

There is a decline in the elephant population in a specific area in Africa. You are an activist trying increase the elephant population. You are required to present a proposed solution to this problem. Create a proposal to solve this elephant problem. Please include the following: Background Information. (Describe the main biome where elephants are located; describe an ecosystem, and describe 4 other types of biomes) Name and discuss how elephants are threatened in Africa. (Research) Discuss how biodiversity can affect the increase and decline of the elephant population. Differentiate between the types of population growth models that can increase or decrease the elephant population. Discuss how community populations relate to your proposal.

A microscopy is a valuable tool that can be used to make observations about the microscopic world around us, and perform investigations that lead to amazing discoveries. There are many different kinds of microscopes and new types of microscopes and as well as modifications to old microscopy approaches are still being designed by scientists. Which type of microscope do you think is the “coolest” or in other words the most useful and efficient? Are there any limitations or setbacks using this kind of microscope? Provide evidence to support your choice. Additionally, investigate and share what kind of notable scientific discoveries were made using this kind of microscopic technique which wouldn’t have been possible otherwise. Make sure to share the references that you selected your evidence from.

Biofilms are implicated in intractable urinary tract infections, in the lung infections (such as in Cystic fibrosis), on teeth, on implanted medical devices-to name a few scenarios. Nosocomial (hospital acquired) infections are the fourth leading cause of death in the U.S. Biofilms contribute to the failure of antibiotic treatment, particularly in hospitalized patients.    In this assignment: Describe   the formation of biofilms, their persistence, and interactions with the host immune system.100 words and should include your explanation of how quorum sensing plays a role in the development of biofilms.  Describe the methods used for controlling medical biofilms.
