3. Compare the Biuret test results of albumin and pepsin, the Benedicts, and starch results for potatoes and onions, and describe how one can determine the relative amounts of sugars present in a sample using the Benedicts test.…
e. Yes, my results do support my alternate hypothesis because firstly, we recorded that the gill cover would unfold more than once when put in an environment with another specimen of beta.…
For the first part of the experiment we found that four of the five pill bugs found their way to the leafy environment. However, most of their time was spent in the section of soil. For the second part of the experiment where we tested each of the pill bugs separately, we found that the bugs spent most or all of their time in the soil environment, therefore, composing the answer to the question of their most favored environment.…

The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately, my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible, Core B was somewhat flexible, and Core A was not flexible and stiff.…

In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate, an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1, we observed the basal rate of three different worms, and then placed the same three worms on different concentrations of caffeine and nicotine. “Caffeine is known to act as an inhibitory neurotransmitter in the brain; it promotes sleep and suppresses aurosal, binding to the adenosine neurotransmitter receptor to block its inhibitory action” (CCNY lab manual, 2014). Before our experiment was conducted we hypothesized that increasing the concentration of caffeine will increase the pulsation rate. During this experiment we used 1.0mM, 3.0mM, and 10.0mM concentrations of caffeine. The highest the concentration the more effect it would have on the pulsation rate, so in this case we could assume that 10.0mM would have the highest effect on the pulsation rate of the blackworms.…
How does sodium chloride in measurements of 0.5%, 2%, 5%, 10% and 15% affect the shoot development, this will be measured from the base of the plant to the tip, of the Phaseolus Vulgaris (green beans)?…
Purpose: In this lab, I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change, and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these changes can be related to everyday life.…
In the experiment involving varying pH levels, E. faecalis, S. epidermidis, L. lactis, and L. casei were subjected to different pH levels and then were allowed to incubate in order to determine the minimum, maximum, and optimum pH levels for growth of specific bacterial species. It was found that lower pH levels between 2 and 4 inhibited or promoted little to no growth for E. faecalis, S. epidermidis, and L. casei. It is evident that these bacteria were resistant to alkaline environments, however, it should be noted that certain mechanisms must have been acquired or involved in maintaining equilibrium within the bacterial cell. High alkalinity generally leads to physiological problems within microbes including the disruption of plasma membrane…
