A hоrizоntаl mаss-spring system is in simple hаrmоnic motion, and the position of the mass can be modeled as x(t) =[0.25m] sin([3s-1]t+π/3), where x is in meters and t is in seconds. At t= 4 s, what is the ratio of the potential energy of the mass to its kinetic energy, U/K?

Questiоn 1: Anаlyzing Cоncepts: Cоmpаre & Contrаst Cellular Organelles Give an in-depth explanation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. The key distinguishing feature separating prokaryotes and eukaryotes is the existence of membrane bound organelles within eukaryotic cells. Each organelle contains its own specialized set of proteins to perform the specific functions of the organelle. Knowing which organelle contains a protein can also give us clues to the function of the protein. Imagine you are studying a novel protein you have creatively named Protinia. You want to determine [where Protinia is normally located within a cell], so you use a procedure called differential centrifugation. As shown in the image below, differential centrifugation allows you to separate organelles based on their size as well as other characteristics. Fig. 1: Tube A shows the mix of all cellular components. The numbers represent ‘spinning’ the sample at different speeds to cause larger particles to ‘pellet’ at the bottom of the tube. The ‘supernatants’ (portion of the solution NOT in the pellet) are then transferred to a new tube and then spun again at a higher speed. Use this figure as well as the following table of information about the organelles to help you answer the questions. Organelle Average Diameter Specific Proteins Present Typical pH Nucleus 7 μm Histones 7.2 Mitochondria 0.7 μm ATP Synthase 8.0 Golgi 100 nm Glycosylase 6.0 Endoplasmic Reticulum 200 nm Glucose-6-Phosphatase 7.2 Lysosome 500 nm Protease 4.0 1A. Plan an experiment using differential centrifugation that will help you identify what organelle normally contains Protinia. State your hypothesis clearly and explain how you will test it. Include what you predict the results may be. 5 pts Copyright 2022 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.
