The composition of biological membranes found in archaea is distinct from biological membranes found in bacteria and eukaryotic cells. The unique lipid composition is thought to afford protection from extreme environments that many archaea inhabit. 10. To survive extreme environments archaea must have very stable biological membranes. Explain how archaea could adapt their biological membranes to survive extreme temperatures. Justify your answer and use the format, “If…, then…” 11. What do you predict would happen if you tried to grow archaea adapted to survive at 100 degrees Celsius at standard room temperature? Justify your answer and use the format,

Use the ecological footprint calculator( https://www.footprintcalculator.org/home/en) to determine how many Earths we would need to live sustainably if everyone lived as you did. You may be surprised. According to the Conversation Ecology textbook, we would need four Earths if everyone lived as the average American did! Next, try the questionnaire again and make one change that you think will reduce your footprint. Then change this parameter back to its original value and try making a different change. Keep track of your results and try this for three different aspects of your lifestyle. What three changes did you make, and which one had the greatest effect on your ecological footprint? Why do you think that this lifestyle change had such a big effect? Is this a realistic change that you might be able to implement soon? Why or why not?

Discuss the major differences between surgical and medical asepsis and how they differ in the nursing care of a patient. Provide the rationale for each example, as well as an example of when each would be used. . (Minimum of 250 words excluding references). Scholarly references are required.

Identify at least two regulatory bodies, and your state’s nurse practice act, that specifies certification, licensure requirements, or scope of practice for your specialty. Discuss the way these influence the educational requirements and experiences for your specialty. Advanced practice registered nurses must incorporate the APRN consensus model in their response. In your response to peers, discuss a specific guideline or change imposed by a regulating body or industry regulation and explain how this affects your daily practice. Cite at least one source to support your response. Use less than 5 years of articles to support

Describe the primary care nursing delivery model along with specific tenets or characteristics from a systems theory or thinking model that makes sense or best depicts the care delivery model. and Explain how the primary care nursing model utilizes tenets or principles of systems theory using descriptors listed below. (Choose 3 from the list below)

1. • Each element has an effect on the functioning of the whole.
   • Each element is affected by at least one other element in the system.
   • All possible subsystems of elements also have the first two characteristics noted above.
   • The health of the overall system is contingent on the subsystem’s functioning.
   • Open to environmental influences (could be external and/or internal).
   • Tends to attempt to self-correct through feedback loop mechanisms (homeostasis – or dynamic equilibrium).
   • Adaptive – can learn; transform and evolve.
   • Input-transformation-output (cause and effect; something done has an impact on something else) phenomenon.
   • Degree/or type of influence (or stimulation) can lead to complex or chaotic systems.
2. Considering the primary nursing care delivery model described in #1, how would you:
   • Approach problem solving­
   • Execute change to achieve outcomes ­
   • Support learning/development ­
   • Respond to new operational challenge
