Biology

 Several bacteria live naturally in the material on your teeth called plaque that contains many different species, which interact with each other in significant ways. Identify some of the problems of studying one of these bacterial species after isolating it through a streak plate procedure and examining its behavior. three or four good sentences

Lab 3 QUESTIONS Remember that molality (m) = moles of solute / kg solvent. So, using your data from Table 1, calculate the moles of each solute (glycerol, NaCl, and CaCl2) used in this lab by using the experimental molality and the mass (in kg) of water in each trial.. You must show all work to receive credit. Recall that the molar mass of a substance is expressed in g/mol. If we have a mass of a substance, and we know how many moles of it we have in that given mass, we can divide g/mol to determine the molar mass. So, using your experimental data from Table 1 and your answer to the previous question, calculate the molar mass for each solute. You must show all work to receive credit. Calculate the percent error for your experimental values for each solute. Is your percent error value relatively constant with each trial? If so, what might this indicate (include accuracy and precision as part of your answer)? You must show all work to receive credit. What are some possible sources of error in your experiment? Discuss at least 3 in detail. Which solution of salt (NaCl or CaCl2) may be better to salt the roads? Why? (HINT: Don’t just focus on the final freezing point in each case—consider all your data and how it may be tied to efficiency and economic factors.)

In this discussion, discuss government-mandated vaccines from a scientific perspective for a bioterrorism event:  Do the benefits outweigh the risks?  Have the side effects been well-documented for these novel vaccines?  What are the risks associated with vaccines approved via the FDA’s two animal rule?  Support your arguments with materials above and from outside sources. Focused on protecting a population from a bioterrorism event. APA format, in-text citation, 1 page, reference include

How does the food pyramid work here? Is this a good tool or have you discovered another? How will you measure success? Take manufactured food and read the label. What are the ingredients? Why would this not be a superfood? Obesity and lack of nutrition cause many health problems. List a disease or condition, and research the best diet and superfoods to fight the condition you selected. Make a menu for a week. What is a nutritional plan that would be best for your health? Why? See what you can include from  https://www.choosemyplate.gov/

The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered. For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned. To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format. Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation in this assignment by the end of the week. Passive Surveillance, For the most part, providers, including physicians and laboratories, are required by state laws to report health conditions. For some communicable diseases, this type of passive surveillance of notifiable diseases helps identify outbreaks, epidemics, pandemics, and possible bioterrorism. Using the South University Online Library or the Internet, review priorities in chronic disease prevention and control. Based on your research and understanding, answer the following questions: Has the focus on disease prevention and health promotion shifted from infectious diseases to chronic diseases? Why or why not? Will a diversion in focus from infectious to chronic diseases leave the United States and other parts of the world at greater risk for pandemics or bioterrorism? Why or why not? How do risk factors and prevention strategies differ from infectious and chronic diseases? When thinking about chronic diseases, how do you perceive the purpose and utility of passive surveillance as an epidemiological tool? Explain with an example of a chronic disease surveillance system. Would you advocate the reporting of select chronic conditions? Why? Give reasons for your answer.Week 2 Group Project DiscussionDiscussion Topic Use this area to conduct your group discussions for the weekly Group Project. This area is only visible to your group and your instructor. Students in other groups cannot access this area.

Photosynthesis is a really cool process that was first used by the cyanobacteria.  These bacteria made oxygen available in the earth’s atmosphere millions of years ago and paved the way for the evolution of aerobic (oxygen-utilizing) organisms like us.  These early-photosynthetic organisms may have been engulfed by a non-photosynthetic single-celled organism to form the first plant-like eukaryotic organisms on the planet.  Plants are highly adapted organisms that use energy from the sun, carbon dioxide from the atmosphere, and water in a series of chemical reactions (utilizing enzymes and electron carriers) to generate sugars.  These sugars are their food source.  It also makes many of them very tasty to us and other organisms.  From the sugars they produce, they can make everything else (nucleic acids, amino acids, and fatty acids) they need to survive, grow, and reproduce. For this reason, plants are called autotrophs.   Auto means self and trophy means nourishing. Animals, on the other hand, have developed along a very different evolutionary line.  We move, hunt down our food, and ingest it to gain our source of many amino acids, sugars, and fatty acids.  We have an elaborate nervous system to sense our environment and transmit this information to a central processing station, the brain, that enables us to react.  We have muscles to move and find food and we often need a lot of food to sustain our activity. We are very social and often engage in battles for the right to mate, be a part of the group, and/or eat.  I wonder if our behavior would change if we became photosynthetic and just hung around in the sun all day like a plant?  I surely hope that wouldn’t mean our brains would become obsolete!  Below are some questions to consider as you write your post: If we were photosynthetic, could sugar alone sustain us?  Hint:  Can you survive on sugar alone now? Would we still need to eat?  If so what and why? How long would we need to stand out in the sun to make enough sugar to provide for our energy needs? How could our epidermis which is made of dead skin cells packed with a protein called keratin be changed back into living cells to sustain the process of photosynthesis?  If not could the underlying living-skin cells be changed into photosynthetic cells? How would carbon dioxide be provided?  For us, carbon dioxide is a waste product of cellular respiration that we expel through the lungs.****Remember to focus your post on only one of the topics presented under the assignment details!****I just realized that the incredible hulk is green.  Maybe his color comes from photosynthesis! If photosynthesis could give me his strength, I might consider being turned green.  On the flip side, I hate insects and they might like to munch on me a bit too much if my skin becomes as tasty and nutrient-filled as the tissue of some plants!  Nevermind, I’ll keep my “omnivorous habits” and forgo the heat and the bugs!

I need a minimum of 200 words for the below question.    No references or citations are necessary. Globally, the human population is increasing exponentially. What are some of the reasons for this population explosion? Do you think this is something that should be controlled? And if so, how might reproduction be curbed? What effects of population growth have you seen in the area you live in? For more information on Reproduction read this: https://en.wikipedia.org/wiki/Reproduction
