Overwintering Turtles and the Implications for Humans
Oxygen is necessary for animal life, a truism that is so ingrained in experience and knowledge that few people stop to consider that many animals can go for significantly long periods of time without taking in oxygen. The freshwater turtle is a wonderful example of this adaptive physiology; it overwinters at the bottoms of lakes, and, to do so goes into a state of hibernation that allows it to live at the bottom of the lake without taking in additional oxygen for long periods of time. Scientists believe that two main physiological adaptations enable the turtles to engage in this behavior. First, the turtles' bodies depress their metabolic and cellular processes, which reduces their need for oxygen consumption. However, dealing with the need for oxygen only solves half of the hibernation dilemma; animals also build up lactic acid and this build up can be fatal. Therefore, it is important to understand how . Second, both the turtle's shell and its skeleton function as lactic-acid neutralizes. Between these two processes, turtles can overwinter underwater at just over freezing temperatures, with no oxygen, and extremely high circulating lactate levels for periods of up to four months. This paper investigates those processes and discusses possible applications for humans dealing with anoxia.
Faith and beliefs in contemporary society
Faith, Religion & Theology, Brennan Hill, Paul Knitter, and William Madges delve into an examination of faith. They begin by distinguishing faith from belief. Next, they discuss how faith relates to the mind, heart, and…
Businesses Have Been Facing Increasing
In this paper, we are seeking to understand the impact of business and management research on a firm. This is accomplished by conducting a study that is focused on: establishing a research direction / problem setting, conducting a literature review, providing methodological justifications and creating a research concept map. Once this occurs, is when we offer specific insights about how these tools can reduce the risks that firms are facing.
