It is only a guess what extremophile might be found next. There are several advantages, and notable disadvantages in terms of the extreme habitats in which these organisms reside. First, and foremost, there is no competition. There are virtually no threats from predators, which is the most common problem for life on earth. Much research has suggested that the existence of extremophiles may have allowed for the beginnings of life on earth to start. According to research, "Their study not only shows us how life functions at what we consider environmental extremes, but also teaches us much about the nature of life itself and about the possible properties of the first organisms that colonized planet Earth at a time when conditions were far more extreme," (Rainey 2006:2). However, there are disadvantages. The extreme conditions do limit the...
Based on the demanding needs of the environment, the organisms will always stay simple ones without being able to evolve much more within the boundaries of their individual habitats.
They could see that nursing staffs were spread more thinly in some hospitals than others. They knew that nurses believe they provide valuable, sometimes life-saving services. The authors connected their issue directly to nursing practice and the quality of patient care. They found that when nurses were responsible for more than six patients, mortality rose 7% and nurse burnout rose 25%. Based on their research, they predicted that 20,000 more
Daryl Bem Daryl J. Bem, Ph.D. is a social psychologist who formulated the self -- perception theory as it relates to attitude change in attitude development. He has exhibited many research interests in his career but is also notable for theories regarding the development of attitudes, sexual orientation, and research attempting to demonstrate the legitimacy of such parapsychological phenomena as ESP. This paper discusses his early life, educational background, his major
For the temperature portion of the investigation (conducted first), eight test tubes were placed in four temperature controlled water baths ranging from water and crushed ice (2( C) to near boiling (98(). The other baths were kept at room temperature (23( C) and an intermediary between this and boiling (75( C). Test tubes were left in the baths for ten minutes, until their temperatures at equalized. Starting with the
Perry M. Smith Ph.D. discusses several relevant issues of leadership in his work of non-fiction entitled Rules & Tools for Leaders. The vast majority of the concepts the author elucidates pertain to change efforts. In terms of leadership theory, there is a general motif associated with Perry's ideas that is in accordance with transformational leadership in which leaders attempt to effect change in a positive way. The book spans
Iso-Electric Point and Iron Content in Iron Hydroxide Impregnated Aluminosilicate-Based Geopolymers Rahil Abou Saleh Dr. Kiril Hristovski Iron hydroxide impregnated aluminosilicate-based geopolymers (Fe-ASG) is a novel water treatment media currently under development for simultaneous removal of arsenic and inorganic contaminants. The goal of this study was to determine whether varied iron contents impregnated aluminosilicate impacts the surface charge in different pH conditions. The study tests for media types of virgin and iron
Enzymes are highly selective and substrate-specific catalysts that work by lowering activation energy for reactions thus increasing the rate of metabolic reactions. In enzymatic reactions, substrates are molecules binding onto enzymes' active sites to form enzyme-substrate complexes (Cornish-Bowden, 2004). Lactose is a disaccharide sugar commonly found in milk and lactase is the enzyme responsible for catalyzing lactose into its subsequent monosaccharide products; glucose and galactose. In line with this, lactose
