Proxima Centauri

Prompt: The closest star to our own, approximately 4.2 light-years away or 25 trillion miles, is the red-dwarf, Proxima Centauri. This low-mass star is about 12% the mass of our Sun, however, a planet has been observed rotating around this red-dwarf star called Proxima c. This exoplanet is approximately 1.3 times the size of earth and appears to have a rocky terrain. Because of its rotation, Proxima c would have approximately 22 Earth days between sunrises and the surface temperature would be approximately -40C. Evidence of both atmospheric and liquid water on the surface has been observed.

Proxima Centauri

Because of the closeness of this planet to the Proxima Centauri, the planet is flooded with 400x more radiation than Earth and a solar wind pressure 2000x that experienced on Earth.[i] Due to these factors, the inhabitants of this planet would most likely live underground and would only venture above ground for resources. They would be bipedal humanoids, resembling humans in their anatomy and physiology. However, considering the differences between Proxima c and Earth, there will be adaptations that would ensure their survival on Proxima c.

Proxima Centauri

Analysis: Using this information, you should describe and justify one adaptation to the nervous system that this organism would have to inhabit Proxima c. This analysis should include the following: · Description of the physiology of the human nervous system (using your textbook as a primary information source). · An explanation of how the environment of Proxima c may affect the functioning of the human nervous system. · Propose an adaptation to the human nervous system the Proxima c humanoid would have to compensate for the environment.

Proxima Centauri

The adaptation can be based on changes in a human organ to make it work more efficiently on Proxima c or can be an organ that is not found in the human nervous system. The proposal should include justification as to why that particular adaption would benefit the humanoid more than any other adaptation to the nervous system. Justifications should be based on known scientific principles and research. Describe how this change or new organ would enable the humanoid to function better on this planet than on Earth.

Proxima Centauri

Use reliable sources and identify the relevant information used for your analysis and justification. Format: 1. Length should be a minimum of 2 pages (down to the bottom of the margin for page 1) and maximum of 3. 2. Analysis should be typed, using 1” margins and double-spacing. 3. Font size must be 12 and should be one of the following: Times New Roman, Arial, or Calibri 4. You must use a minimum of 3 reputable sources in addition to your textbook. Reputable sources include peer reviewed scientific journal articles, accredited websites, or books. Google, Wikipedia, etc. are not acceptable sources.  https://youtu.be/SAcanmnDCeI
