Introduction: There are times when it is necessary to go through something both inside and outside‚ literally‚ to learn. This was exactly the case with virtual lab #11 where the experiment called for an examination of an earthworm’s exterior anatomy and interior anatomy. The earthworm as a whole is considered the dependent variable as we cannot change it. However‚ the labels to be placed can be moved so they are the independent variables. My hypothesis is quite elementary. I believe that after studying

Hypothesis: The higher the salinity content in the water the lower the gross primary productivity values. Variables: Control- The group with zero salt added. Dependent- Dissolved oxygen reading. Independent- The salt concentration in the water. Introduction: On the surface waters of lakes and oceans‚ plants are mainly unicellular algae‚ and most consumers are microscopic crustaceans and protozoans. Both the producers and consumers are very small‚ and they are easily contained in a liter of water.

Lateralized Stroop Effects Andrew Hanna Psychology Program Arizona State University‚ Tempe‚ AZ Introduction Through broad literature review the stroop effect can be explained through demonstration of a reaction time of a task. We built upon the basic ideas developed in the previous Stroop models of MacLeod in 1991‚ Belanger & Cimino in 2002‚ and J.R. Stroop‚ the first person to publish its significance in English in 1935(Stroop‚ 1935). In the Stroop model‚ color-words are variously presented

Post lab The unknown solution 4055 was tested by the separation scheme in order to identify the four cations that exist in it. The cations found were Ag+‚ Ba2+‚ Mn2+‚ and Ni2+. When I added 5 drops of 3M NaCl to the unknown solution‚ we had some precipitate‚ we centrifuge and then we divided to two test tubes‚ and they were put in hot water and got confirmatory tested. The Ag+ appeared to be in the solution because it melted‚ however Pb2+ didn’t. With the rest of the solution we added Na2SO4 we had

Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

soil from the site and then take several other samples from different points on the site. This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests. In order to turn my soil samples

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light
