Your lab partner did an experiment where he added drug to a tissue, he thinks the drug caused receptor desensitization. He froze the tissue so it could be used in biochemical assays. What experiment would you do to test if the desensitization is the result of acute or chronic drug exposure? How would you interpret the results obtained?

Your lab partner combined chloroform (CHCl3) and acetone (C3H6O) to create a solution where the mole fraction of chloroform, Xchloroform, is 0.139. The densities of chloroform and acetone are 1.48 g/mL and 0.791 g/mL, respectively. Calculate the molarity of the solution.? Calculate the molality of the solution.?

George was a participant in a visual priming experiment. He thinks that according to the study, subliminal perception can greatly influence behavior. He asks your opinion about purchasing subliminal message CDs to help him quit smoking. Research and describe some of the history of subliminal messages, their origins, and use in pop-culture. Research the online library for scholarly articles on subliminal messages and explain what you found regarding their validity. Based on what you found compare and contrast the validity...

You and your lab partner are studying the rate of a reaction, A + B --> C. You make measurements of the initial rate under the following conditions: Experiment [A] (M) [B] (M) Rate (M/s) 1 1.4 1.2 2 2.8 1.2 (a) Which of the following reactant concentrations could you use for experiment 3 in order to determine the rate law, assuming that the rate law is of the form, Rate = k [A]x [B]y? Choose all correct possibilities. [A]...

You’ve got a problem in the action potential lab at “Organelles R Us.” Your lab partner has spiked the axon cultures with ouabain. Realizing that the depolarization and repolarization phases of the action potential are actually due to passive movement of ions through channel proteins, and that passive transport will eliminate concentration gradients, explain what happens (and why) to your cells’ ability to generate action potentials in the short term and in the long term.

In our physics lab, we did a experiment regarding Hooke's law, and the goal is to find the spring constant by using a simulation. In the first section of the procedure, our instructor intentionally give us the wrong instruction, which tells us to find spring constant using varying mass, delta x and constant gravity. In the second section of the procedure, we need to figure out what went wrong in the first section that caused us to incorrectly measure the...

An experiment is planned where an automatic lab would be sent to the surface of Saturn. If there was life in Saturn, the probability that the lab detects it and correctly reports the finding is 0.5. If there never was life on Saturn, the probability that the lab will erroneously indicate the presence of life is 0.45. Suppose that a fair assessment of the probability that life was ever present on Saturn is 0.1. (a) Find the probability that the...

Pretend you and your lab partner are designers for the PhET simulations and want to make a simulation for students to investigate gravity fields. Think about what you know about gravity and what kinds of experiments a student might want to do to learn about gravity. You may have to refresh your memory by using the text. Draw a design, by hand, for a gravity simulation. Explain why you included each component and explain at least one experiment that a...

Chemistry question: We did an experiment in lab and I need to figure out how to A) calculate the mols of NaOH used in titration B) calculate mols HCl in titration C) calculate mols of CaCO3 reacted D) calculate grams of CaCO3 reacted E) calculate percentage of CaCO3 in TUMS. I really need to see all the steps that way I can understand what is going on. We did four titrations with the following information 38 mL HCl, 19.913 g...

A group of students, performing the same Uniformly Accelerated Motion experiment that you did in lab, dropped a picket fence through a photogate and obtained the following data from the computer. Blocking Times (s) 0.05206 0.08969 0.12076 0.14763 0.17203 0.19438 0.21502 The band spacing is 0.06 m. (a) Use Excel to do the following. (You will not submit this spreadsheet. However, the results will be needed later in this problem.) (i) Calculate the accelerations. (ii) Calculate the average of the...
