Mechanisms of Evolution Lab Group Members Names: Miles Connolly Wendy Mosqueda-Lopez Christina Benson Nancy My Miyagi Paz Scenario #1 – Hardy-Weinberg Equilibrium: 1. What is the Hardy-Weinberg equilibrium used for? The Hardy-Weinberg equilibrium is used like a punnett square to see if genotype frequencies in a population remain constant from generation to generation. 2. What are the conditions that must be met in order to apply the Hardy-Weinberg equilibrium? The conditions that need to me

Another way to visualize the pseudo-randomness properties of the $k$-logistic map is by means of the phase diagram, or Poincar\'{e} map, which maps the value of $x^k_{t+1}$ against $x^k_{t}$ of a given orbit, or even three-dimensional by mapping $x^k_{t+2}$, $x^k_{t+1}$ against $x^k_t$. Thus, Fig.~\ref{fig:poincareLogistic} shows the phase diagrams of the $k$-logistic map for three different orbits $\mathcal{O}^{k}$. We can observe that the phase space is filled, i.e. it almost produces all possible

At the time of testing Jack, a male, was three years, three months, and thirteen days old. For the auditory comprehension portion of the assessment, he had a raw score of 42 and a standard score of 108. Based on the confidence interval, we are 95% confident that his true standard score falls between 99 and 115. These scores indicated a 70% percentile rank. Based on the standard score, we are 95% confident that his true percentile rank does fall between 47 and 84. His age equivalent for the auditory

“Procedure A: Investigating How Length Affects Pitch” Lab Report Brenna Ketchum Research Question: How does the length of how much a meter stick is hanging off of a table affect the pitch, when the meter stick is plucked, and how does the length of a kazoo affect the pitch, when it is hummed into? Hypothesis: For the meter stick tests, when there is 20 centimeters off of the table, the pitch will be high, and will not vibrate for very long. For the next test, when there is 40 centimeters off

Despite our preparation in developing our evaluation tools, there were a few challenges during the implementation stage. Many participants arrived, and either missed completing the pretest survey, or were unable to focus as the workshop had already started. A few others left the workshop early and not able to participate in the posttest. Another re-occurring theme was missing identification on the surveys. Although our group encouraged participants to write their initials or another non-identifying

Limitations by their very definition are factors that cannot be seen or controlled. Several of these limitations were discussed in Chapter 1, other limitations were realized after the study had begun. The first of these limitations became apparent in the collection of 2013 – 2014 CDT data. Two hundred thirty five students had taken both the CDT and Keystone exams in the 2013 – 2014 school year. Three hundred thirty students had taken both the CDT and Keystone exam the following year. The population

Question #1 Replication occurs when researchers apply an existing theory to new situations. This is often used to test the generalizability of different subjects. This subject group can include any type of variable such as age, race, location, and culture. The main goal of replication is to make sure previous results are valid, to determine the role of extraneous variables, to see how the theory is affected in new situations, and to inspire new research. Sometimes when replication is done results

For this lab 6 male Acheta domesticus were isolated in plastic containers, each was placed in a container that was 5 cm height and had 5.5 cm radius. Each of these containers was punctured with 10-15 minuscule holes for breathing on the lid and 5-8 holes on the sides. Inside of each container a damp paper towel was placed on the bottom and 2 pieces of food were placed on the paper towel. The Acheta domesticus were kept isolated in their personal containers for 7 days. At the end of these 7 days we

Polarization in political views and loss of confidence in government? Introduction The main political divisions in the United States are into two parties - the Republicans and the Democrats. A recent (Pew Research study) [http://www.people-press.org/2014/06/12/political-polarization-in-the-american-public/] noticed a growth in ideological consistency within the parties, with the overlap in conservativeness and liberality shrinking between 1994 and 2014. This polarization of political views could
