1. Select only ONE of the following environmental stresses: (a) heat, (b) high levels of solar radiation, (c) cold, or (d) high altitude. Discuss specifically how this environmental stress negatively impacts the survival of humans by disturbing homeostasis. - The environmental stress I chose to analyze was the cold. This stress negatively impacts our homeostasis with how it forces our bodies to adapt to the temperature change. If cold enough, our bodies will start to adapt by implementing a number of short-term adaptations. The most common illness that can come from too cold of conditions is hypothermia and this is when the body is dissipating more heat than it is absorbing. 2. Identify 4 ways in which humans have adapted to this stress, choosing one specific adaptation from each of the different types of adaptations listed above (short term, facultative, developmental and cultural). Include images of the adaptations. - In order to adapt to ...
