The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4. INTRODUCTION The 2002 scientific journal‚ “The Costs and Benefits

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount of PH in each plot’s soil. The hypothesis was incorrect; there was not a significant difference in the means of the PH from the oldest plot compared to the youngest plot. Introduction The definition of vegetation is plants considered collectively especially those found in a particular area

Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

Economic Indicators Paper What does it mean when someone refers to the health of an economy? Furthermore‚ how can one classify an economy? Americans love to quantify data. Because of this inherent need to compare data‚ economists have developed a way to collect nearly every type of statistics that may reveal the general health of the economy. These statistics actually tell if the economy is productive and efficient or if it is slow and inefficient. Included in these statistics are Gross Domestic

Maternity leave Introduction At present‚ almost every country has provisions for maternity leave that provided to the female employees. Most industrialized countries have some form of maternity or parental leave policy that effectively grants employment protection to women around childbirth and in some cases to either parent for an even longer period after childbirth (Puhani and Sonderhof‚ 2009). Maternity leaves are the temporary leaves that allowed by the company or institutions to a female

As people began drinking their tea‚ they came up with tasseomancy‚ or tasseography‚ which is just a type of tea leaf divination. People prefer divination by tea leaves because it is the easiest and most accessible for everyday people. It is a form of scyring. First of all‚ Tea is poured into a cup without a strainer‚ and the
