3.3 Lab Analysis

When the pH is not at its optimum, the differing pH's will disrupt the bonding between the R groups of the amino acid causing its structure and the shape of the activation site to change

Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions.

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

Day 1. Michael was coming home for vacation from college. When he got home he found out that

3.6.1. BAP (Benzyl amino purine) stock solution (2mg/ml): 20mg of BAP being weighed and dissolved completely in 1N NaOH to a final total volume of 10 ml with autoclaved double distilled water to obtain a stock concentration of 2mg/ml was prepared and stored in clean autoclaved vials at -4°C.

Remove the cockroach from it habitat and submerge it in ice water for a few seconds to paralyze it. After the cockroach is paralyzed, using the surgical tools cut a leg (at the hip). The leg should be placed on the cork of the spike box, allowing a bit of the leg to overhang. The stimulation electrode should be placed on the femur and COXA then the electrodes should be connected to the output of the TENS electrical stimulator. Using the provided LabVIEW program, the onset stimulation delivered to the leg as well as its duration can be controlled. The stimulator should be turned on with the correct corresponding channels by turning the knob clockwise, the current intensity of the impulse increase further when the knob is turned clockwise. A

In this lab we will be studying electric field plotting through the use of various apparatus. The equipment we will be using includes a digital voltmeter, voltage probes, carbonized acetate sheets, battery, and other tools of measurement. The goal of the lab is for us is to be able to plot lines for charge distributions and to create electric field lines by providing an electric current through carbonized sheets. Once we have completed constructing the electric field lines for the plate charge distribution, we will continue to calculate for the electric field (E = Vx) and begin to plot for the dipole charge distribution. When we have collected all the data needed, we then will finish calculating for all the remaining variables and complete the rest of the lab report.

A) Describe in your own words, in as much detail as you can, the anaerobic metabolism of glucose to pyruvate. B) Draw this pathway (by hand), indicating all substrates, enzymes, cofactors and products. (You do not need to include reaction mechanisms.)

P is the reflectance proportion of EMR, M is the outgoing reflectance and E is the incoming reflectance. So in order to find the reflectance we are dividing the outgoing (M) reflectance to the incoming reflectance (E).

From the Client VM, clear Internet Explorer’s cache (or completely close and reopen IE) and go to http://10.0.0.1 What do you notice? Record your observations. These observations will help you with your lab report. The web page does not load stating “Internet cannot display the web page.”

Figure~\vref{fig:res}, shows the characteristic functions of the classes of the linear power amplifiers in which the active device operates as a current source. Its major disadvantage is holding a voltage to the transistor terminals during the conductance of the current, resulting in power dissipation. As shown, classes A and B are linear, while class C is incapable of storing amplitude information, hence often not be considered one of these classes.

In experiment 3.11, we found out whether or not a larger amount of a liquid would get hotter when it boils. To answer this, we heated a specific amount of unknown liquid and recorded the temperature every fifteen seconds. In our scatter plot, we were able to find the boiling point of our liquid. We know that the slope of our graphs is when the liquid molecules were moving around and heating up. The plateau of our graph points is where the liquid started to evaporate and boil. This is were we found our boiling point at. Shantel and I decided that our boiling point was about 98º Celsius. If you had another slope in your graph, that was when you were simply heating the leftover gas. The histogram showed us that there were about equal amounts of data in the higher temperature (about 95º Celsius) bins for both 20mL of liquid and 10mL of liquid. Also, in the lower temperature bins (75º to 80º Celsius) there was about equal amount of data for 20mL of liquid and 10mL of liquid. There was 7 pieces of data for 10mL of liquid in the lower bins, and 6 pieces of data for 20mL of liquid. If a larger amount of liquid did have a higher boiling point, the clusters would be organized by volumes or amount. For example, all of the 20mL pieces of data would be in the higher temperature bins, and all of the 10mL pieces of data would be in the lower temperature bins or flipped. Rather, the bins were clustered by identity. The boiling point is a characteristic property.

How do you do thermal sharing between two system when their thermal constant is different? have you done any implementation on this?

Once the hairs ran through a microcopy scanning, the stub and hairs were then sputter-coated with gold-palladium. The third method was to analyze the hair length and diameter of the marine species. As seen in the previous method, the same was done here. Three
