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.

effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water. We measured

Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution. Methods Verification of the Henderson-Hasselbalch equation

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

Peter Agre’s Discovery Figure Page Figure 1: Figure 2: Upon deciding a topic for an ideal Nobel laureate‚ I had to meet two criteria I decided for myself. Aside from the topic having to be science related‚ I decided that the laureate could not be well know‚ such as Watson or Einstein‚ and also it should be a science topic that I have found the most intriguing since entering college which happens to be the human body. Even with such a broad topic as the human body I came across a laureate

A Critical Analysis of the Effects of Chemical Castration and Physical Castration on the Recidivism Rates of Sex Offenders Introduction This paper examines the effects of chemical castration and physical castration on the recidivism rates of sex offenders. Using theory integration or the multifactor approach‚ the findings reveal there are several factors influencing sex offender recidivism. Both chemical castration and physical castration have the potential to reduce the recidivism
