In the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

Using FIT with theses adjusted patterns I feel confident that I will complete this assignment

Snowden Paper Critique: Visual Attention to Color: Parvocellular Guidance of Attentional Resources? 1. The independent variable of the experiment is luminance and it has 3 levels: light, equiluminant, and dark. The dependent variable is the reaction time (milliseconds). 2. One methodological limitations of this study is that the magnocellular cells responded to a chromatic change so the results could have been skewed and therefore made them inconclusive even though the experimenters tried to control for it.

After I changed the rate of growth as well as years for each data line the difference begin to take form as time and growth

Observations: 1. The first step had to be repeated due to not following proper instructions. I did not grease the screw, so as I was shaking the mixture, solids were forming around the screwpart of the separatory funnel. 2. When adding 5.0 mL of NaOH to the unknown mixture and shaking it for about 30 seconds, layers had formed.

1. List the three methods heat is transferred? For the pre/post test, a majority of students correctly listed the three methods of heat transfer. This question ranked as the highest correctly answered question in both the pre/post tests.

1. Why do astronomers think that there may be other advanced civilizations? Astronomers think there may be other advanced civilizations because the universe is billions of years old. There are many other planets out there like Earth that are sustainable for life, even if we have not yet found those planets. They reason that of all the planets and galaxies there is great possibility of life, due to the length of time that the universe has existed and expansive array hospitable planets.

The Women’s Room and The Radiant Way are 2 novels that reflect certain ideologies of the time they are written. The Women’s Room is written by American author Marilyn French.
