question sci115

Pick one of the following topics and write a primary post. Also, please make a substantive reply to one of your fellow students.

Topic 1. Cooperative relationships between microorganisms. Gearin (2016) describes cooperative relationships between different species of microscopic organisms called syntrophy. Answer the following two questions about this arrangement:

  • (a) What are the main characteristics of their partnership?
  • (b) How does each species benefit?

Topic 2. The Hawaiian Bobtail Squid and its bacterial endosymbiont. In a 4 minute video clip (iBioEducation, 2013), Bonnie Bassler explains the relationship between the Hawaiian Bobtail squid and it’s endosymbiont, the bacterium Vibrio fisheri. Answer the following two questions about this arrangement:

  • (a) What are the main characteristics of the partnership between these two species?
  • (b) How does each species benefit?

Topic 3. Hazardous Research on Viruses. In a editorial, 3 years ago, Marc Lipsitch (2014) blasted certain types of virus research as too risky. My immediate gut reaction was that Prof. Lipsich was unduly scaring the public by overstating the risks. Upon further reflection, I’ve come to the opinion that Prof. Lipsitch’s concerns may well be justified. Based on the articles by Lipsitch (2014) and Wahlberg (2014) answer the following two questions:

  • (a) What are the benefits and the risks of this research?
  • (b) Do you feel this research should go forward (and why)?

Assessing Your Diet Using the Dietary Guidelines for Americans

The following are the Dietary Guidelines for Americans, 2015 Key Recommendations. These Key Recommendations are the most important in terms of their implications for improving public health. To get the full benefit, individuals should carry out the Dietary Guidelines recommendations in their entirety as part of an overall healthy eating pattern.

7. For each recommendation, check the box to the left if you are currently following the recommendation.

USDA Dietary Guidelines 2015 Key Recommendations

  • Saturated fats and trans fats, added sugars, and sodium

Key Recommendations that are quantitative are provided for several components of the diet that should be limited. These components are of particular public health concern in the United States, and the specified limits can help individuals achieve healthy eating patterns within calorie limits:

  • Consume less than 10 percent of calories per day from added sugars
  • Consume less than 10 percent of calories per day from saturated fats
  • Consume less than 2,300 milligrams (mg) per day of sodium
  • If alcohol is consumed, it should be consumed in moderation—up to one drink per day for women and up to two drinks per day for men—and only by adults of legal drinking age.
