Your friend is worried about the many vaccines that his newborn son is scheduled to receive and asks you for advice since you are taking a biology course. In order to help him make an informed decision about whether to allow his son to be vaccinated, you prepare a PowerPoint presentation in which you: 1) Explain how vaccines work. 2) Briefly contrast the traditional methods used to create vaccines with more recently used biotechnology techniques. 3) List some of the diseases that babies and children in the USA are routinely vaccinated against. 4) Share how vaccinations have impacted the frequency of these diseases over the past 100 years. 5) List reasons why people are worried about allowing their children to be vaccinated, including any scientific evidence to support these concerns. 6) Conclude with advice to your friend regarding vaccinating his son, based on what you learned from reliable information sources.

Answer questions to three (Learning Objectives) LO4 Summarize the possible effects of smoking, alcohol, drug use, and environmental hazards in the embryo and fetus? LO6 Explain the three stages of labor and the events that occur in each? LO8 Discuss the benefits of breast-feeding? You can keep the answer short and straight to the point to meet the word count.

You will pick a microorganism for your paper on pathology or microbe-environment interactions. The organism can not be one of the ones your instructor goes over during lecture listed in the syllabus(prokaryotic and eukaryotic cells). Select a pathogen/microbe from current events that is an emerging or reemerging concern to you or people in your area. Provide local epidemiological data/statistics for the organism. The paper must be in APA format and 2-5 pages. Your paper must include: • Introduction to the organism (structure, cell type, morphology, metabolic requirements, natural reservoir, history, etc.) • Introduction to the disease(s) caused by the organism (epidemiology, signs, symptoms, etc.) OR introduction to the environmental impact of the organism • List and describe factors employed by the organism to assist in its growth, reproduction, culture conditions, host/pathogen interactions and/or virulence. (e.g. nitrogen fixation, symbiotic interactions etc.) Categorize virulence factors by mechanisms of action (Immunity Avoidance, Tissue/Cell Lysis, Colonization/Spread) • Discussion of treatment/prevention options for the disease(s) caused by the organism (Antibiotics or other chemotherapeutics given as part of treatment and their mechanisms of action, Vaccines available and type) • 3 primary and at least 2 secondary scholarly sources

Student Instructions For each assignment, you will use the M.U.S.E. link to complete the lab. In this lab, you will see the impacts associated with coal-fire or nuclear power plants for electricity generation. This will help you write a scientific paper that focuses on energy sources. Energy Sources Everything people do in their daily lives involves the consumption of resources. One resource in particular is energy. Electricity is one of the most important energy resources consumed. Electricity is also one of the highest in demand. Traditionally, fossil fuels have dominated the U.S. energy mix. Examples of fossil fuels include: Coal Natural gas Oil However, it is well-known that fossil fuels emit carbon into the environment. This is harmful to the environment because fossil fuels are contributing to global warming. Fortunately, alternative energy sources are becoming more efficient and popular. Examples of alternative energy sources include: Solar Wind Hydro Geothermal Analyze energy sources, to write a scientific paper that addresses: The 2 primary sources of electricity generation are coal and nuclear power plants. Which of these sources is better for human sustainability? Using the M.U.S.E. link, review the background information and gather your data. Review this video for a detailed overview of this assignment: https://breeze.careeredonline.com/pa30gmoj8hh1/?launcher=false&fcsContent=true&pbMode=normal . Then you will use the Lab 4 worksheet for assignment instructions and data collection. Be certain to compete both Part 1 and Part 2 of the worksheet.

You will Have to research the life history of your organisms using PUBMED/NCBI with respect to 1. Evolutionary biology and phylogenetics, 2. Ecology and 3. Two other sub-disciplines in biology (e.g. reproduction, molecular biology, physiology, etc.). You must clearly create four sections in your report one marked “Evolution”, two marked with the other sub-disciplines, and one marked “Ecology”. Your report should be around two pages in length with four subheadings (as described above). Work cited (four references minimum) is not part of the page count. Please use font 12, Time New Roman, double spaced, one inch margins all around to construct your document.

Based on your knowledge of bacterial cell structure, cell wall composition, toxins that they produce, and metabolism, design the ultimate pathogen that you think will win the battle against human body’s immune responses. First describe the various cell structures your bacterium will have and how these will help it to combat the human immune system. In your essay talk about the cell wall composition in detail and the specific types of toxins that your bacterium will produce. Also describe why you think that this bacterium will be an ultimate pathogen and how the structures and toxins will help it to evade our immune cells. please use scientific sites for sources. no .com.

Each student must complete a (5-7) page, double-spaced research report on a obesity related to human biology, pathology, or human environmental biology. This report must be typed or word- processed and must have standard 1-inch margins. Must use a minimum of three separate sources for their research, including scientific journals, books, magazines, and newspapers. Use APA style.

Assignment – The human body is a whole consisting of the following systems that are interconnected: integumentary, skeletal, muscular, nervous, sensory, endocrine, cardiovascular and lymphatic, body’s defense, respiratory, digestive, urinary, and reproductive. Explain the major functions of each system and link one function to another system explaining how the two systems are interconnected. You can start with any system that you like. Example: 1. Start with the skeletal system that has the following functions (explain each function): support for soft tissues, movement gives a place of attachment for muscles, protection internal organs, storage of minerals (particularly calcium and phosphorus), storage of fat, and production of blood cells in the marrow of certain bones. 2. Then select one function like production of blood cells and discuss the cardiocirculatory system functions (explain briefly each function: gas exchange (red blood cells), blood clotting (platelets), defense (white blood cells) 3. Link white blood cells to protection from diseases and talk of the lymphatic system functions (explain briefly each function). Protecting body against pathogens, remove cellular waste, absorb fats from digestive system. 4. and then continue to link to digestive system and so on…….
