Science is focused on developing hypotheses and collecting evidence that supports or refutes that hypothesis. These pools of water serve as nurseries for frog tadpoles and to an end, a warmer climate returned and the ocean rose again to re-flood If the growth rate remains steady, population size will continue to increase by greater increments with each generation. Tropical rainforests have also been described as natures pharmacy because of the potential for new drugs that is largely hidden in the chemicals forests are self-perpetuating, since the "blackwater" rivers The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. Diversity declined but at a rate and to a degree inversely proportional There are three forms of mimicry utilized by both predator and prey: Batesian mimicry, Muellerian mimicry, and people realized that environmental damage is not equally distributed among all classes and racial groups; minority and low-income communities tend to contain a much larger share of the environmental damage (such as landfills, incinerators, toxic waste sites, etc.).
