Circadian rhythms allow organisms to anticipate and prepare for precise and regular environmental changes. They thus enable organisms to best capitalize on environmental resources (e.g. light and food) compared to those that cannot predict such availability. It has therefore been suggested that circadian rhythms put organisms at a selective advantage in evolutionary terms. However, rhythmicity appears to be as important in regulating and coordinating internal metabolic processes, as in coordinating with the environment. This is suggested by the maintenance (heritability) of circadian rhythms in fruit flies after several hundred generations in constant laboratory conditions, as well as in creatures in constant darkness in the wild, and by the experimental elimination of behavioral, but not physiological, circadian rhythms in quail.

For what do Circadian rhythms let an organism prepare?
Answer: environmental changes

According to the 2002 Census, 4.6% of the Chilean population, including the Rapanui (a Polynesian people) of Easter Island, was indigenous, although most show varying degrees of mixed heritage. Many are descendants of the Mapuche, and live in Santiago, Araucania and the lake district. The Mapuche successfully fought off defeat in the first 300350 years of Spanish rule during the Arauco War. Relations with the new Chilean Republic were good until the Chilean state decided to occupy their lands. During the Occupation of Araucania the Mapuche surrendered to the country's army in the 1880s. Their land was opened to settlement by Chileans and Europeans. Conflict over Mapuche land rights continues to the present.

What is the name for the Polynesian people living on Easter Island?
Answer: the Rapanui

Comcast has been criticized for multiple reasons. The company's customer satisfaction often ranks among the lowest in the cable industry. Comcast has violated net neutrality practices in the past; and, despite Comcast's commitment to a narrow definition of net neutrality, critics advocate a definition of which precludes distinction between Comcast's private network services and the rest of the Internet. Critics also point out a lack of competition in the vast majority of Comcast's service area; there is limited competition among cable providers. Given Comcast's negotiating power as a large ISP, some suspect that Comcast could leverage paid peering agreements to unfairly influence end-user connection speeds. Its ownership of both content production (in NBCUniversal) and content distribution (as an ISP) has raised antitrust concerns. These issues, in addition to others, led to Comcast being dubbed "The Worst Company in America" by The Consumerist in 2014 and 2010.

It has been alleged that Comcast's internet service has done what to customers?
Answer:
has violated net neutrality practices
