Imagine in the last lab you ran your samples on your gel and find that the only bands you see on the gel are from the ladder. All 4 lanes where you loaded your paternity project PCR reactions are blank (no bands). Assume that you did the DNA preps for all 4 (child, mom, father 1, father 2). From the list below, check off all plausible answers that could account for this.

Alternative Software Choice - Joomla 1.5 Alternative Software Tool Wiki In this Wiki you will "claim" a piece of alternative software that is NOT an operating system. The alternative software can be in the Productivity, Collaboration, or Business software category. After you've "claimed" the software tool, you will write an editorial evaluation of the software tool in the Wiki. You must first post to the Wiki with your claim of a software tool, since no duplicate software tools are allowed, you must first make sure that your choice has not been claimed. If it has been claimed, you must make another choice. The key to this activity is to first read the wiki and make a claim by posting to the wiki with your claim date. Next start the research and post your editorial evaluation later in the week. If I find a duplicate, the first student's claim will be honored and the second student will receive no more than 50% of the value of this assignment. Your editorial evaluation of the alternative software tool must include the following: Size of the download What commercial software tool it is an alternative for What category the software is found in Skill level you think is required to install & use the software tool How much does the alternative cost for home use? AND how much for commercial use? (yes it can be different) Do you, or would you, use this alternative software tool? Why did you select this software tool?

Two different tanks containing water and oil were connected by a triangular gate that can rotate around point A. The depth of the gate is 6 m and the base of the triangle is 4 meters. The tank filled with oil is 6.23 m long and the tank filled with water is 6 m long. If it is known that the gate is at balance (it is not rotating) around A, calculate the specific weight of the oil. (Density of water is 1000 kg/m3) (Hint: follow the steps below: -What is the resultant force of water acted on the gate and where is the center of pressure of this force? - What is the resultant force of oil acted on the gate and where is the center of pressure of this force?)

The National Academy of Science reported that 41% of research in mathematics is published by US authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 41%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 186 recent articles published by reputable mathematics research journals and finds that 92 of these articles have US authors. Does this evidence support the mathematics chairperson's claim that the percentage is no longer 41%? Use a 0.05 level of significance. Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.
