Select True or False for each of the following statements: In GWAS, most statistically associated variants are causal/functional variants. In other words, most of the time a SNP allele at a statistically significant SNP locus will increase risk for the disease/phenotype being investigated by the GWAS. [false1] With GWAS it is relatively easy to detect risk variants that are rare with a small to moderate effect size using GWAS. [false2] A GWAS has the power to detect variants with very small effect sizes if the sample size is at least two thousand. [false3]

Fill in the blanks with the best answer from the dropdown menu. Use each item from the dropdown menu only once.     In the immune system, the complement cascade tags [pathogens] for [phagocytosis] by [immunecells]. In the brain, the complement system may tag [synapses] for [pruning] by [microglia].

Pretend you are a scientist who has just conducted a GWAS. Your GWAS shows SNP 1 in the image below as the lead SNP associated with a disease. (This would be the SNP with the tallest peak on your Manhattan plot.) SNP 1 is in a non-coding region of the genome, so it’s not clear how a SNP allele at this locus would increase risk for disease. Thus, you look for more information to make a hypothesis about which SNP locus might be the functional/causal SNP (i.e., the locus with a SNP allele that actually increases risk of developing the disease). You have the information below:   Based on the information above, the best hypothesis is that SNP [2] is the functional SNP. (Keep in mind, you will need to do more experiments to provide evidence to support this hypothesis.) From the list provided, which SNP is in linkage equilibrium with SNP 1? [4]

A patient with stage IV cancer reports fatigue interfering with daily routines. Which outcome measure is best to assess this symptom?

Based on the typical postural changes that occur with Alzheimer’s Disease, which of the following intervention sets form the MOST appropriate plan of care?

For individuals with Alzheimer’s Disease and gait deficits, what type of learning strategy is MOST beneficial?  

A student has a laptop computer running Windows 11.  The computer has a 1 TB solid-state disk and 16 GB of RAM. The student installs VMWare Workstation Pro on the laptop.  The student then creates a virtual machine (VM) with 4 GB of RAM. How many instances of this VM could be run at the same time on this computer?

Virtualization has several benefits and several risks. Explain the most important risk that should be considered when virtualizing multiple guests on one host, as discussed in a lecture in this course. Note: The terms “guests” and “host” are used here in the same manner as they are used by VMWare in relation to the VMWare Workstation application.

PROBLEM 3: Moisture content is a critical parameter in geotechnical engineering because it directly influences soil behavior. By analyzing soil samples, engineers can assess soil uniformity, predict performance under load, and recommend stabilization measures if needed. The moisture content found in 30 soil samples from the same location was found as follows: 0.245 0.295 0.271 0.325 0.329 0.321 0.316 0.350 0.249 0.291 0.287 0.253 0.284 0.361 0.312 0.302 0.279 0.317 0.280 0.257 0.268 0.332 0.265 0.305 0.345 0.290 0.308 0.298 0.274 0.263   Determine de mean, standard deviation, minimum, and maximum value of the data sample. Divide the data into six intervals, use the same length for them, and plot the corresponding histogram. Create a pie graph showing the relative frequency of this data for the same intervals. Plot the normal distribution using the NORM.DIST function with the mean and standard deviation of this data, and compare this distribution with the probability distribution function (PDF) of your data. Is this data normally distributed? SAVE YOUR EXCEL FILE AND SUBMIT IT USING THE LINK BELOW BEFORE THE TIME OF THE EXAM ENDS

PROBLEM 2: In municipal water supply systems, engineers must calculate flow rates in interconnected pipes to ensure adequate pressure and delivery. Consider a pipe network with four interconnected pipes with unknown flow rates Q1, Q2, Q3, and Q4. Conservation of mass and conservation of energy principles enforce the water supply system to satisfy the following set of linear equations: Use Excel to write the coefficient matrix and right hand side vector for these set of linear equations. Determine the inverse of the coefficient matrix. Find the solution for the flowrates Q1, Q2, Q3, and Q4 that satisfy the equations using the inverse matrix method. Use Solver to find the solution for the flowrates Q1, Q2, Q3, and Q4 that satisfy the equations. Select the last equation as Objective and the other three equations as constraints. Compare your solution to the one in part C. SAVE YOUR EXCEL FILE AND CONTINUE TO THE NEXT PROBLEM
