Describe your ideas about why indigenous groups of people in different parts of the world have different skin colors from other groups of people and use at least three different types of evidence that supports your ideas. (3pts)

The indigenous groups of individuals in distinct parts of the world possess different skin colors from other groups of individuals. Following are the different kinds of evidence, which supports the idea:  

1. The individuals would have moved around the globe, however, they would have still kept their skin color DNA.  

2. There also would have been more individuals living all over the globe and the skin color of the individuals would have changed gradually with time.  

3. Living at higher altitudes would have resulted in more variation as the amount of exposure would have been different from the individuals moving around the world.  

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.  

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
