2. A clinical trial is conducted to evaluate the efficacy of a new drug for prevention of hypertension in patients with pre-hypertension (defined as systolic blood pressure between 120–139 mmHg or diastolic blood pressure between 80–89 mmHg). A total of 20 patients are randomized to receive the new drug or a currently available drug for treatment of high blood pressure. Participants are followed for up to 12 months, and time to progression to hypertension is measured. The experiences of participants in each arm of the trial are shown below.New Drug

I need help completing the post-lab data analysis for my report on the measurement of chloride in local water samples. Below are the class’s average volumes of 0.010M AgNO3 added for each of the three samples (tap water, lake water, and effluent).

-Volume of silver nitrate used (Tap Water) = 8.22 mL

-Volume of silver nitrate used (Lake Water) = 21.10 mL

-Volume of silver nitrate used (Effluent Water) = 22.77 mL

With that information I have to answer this question:

  1. Moles of Cl- reacted

Hint: The chemical equation for the reaction of chloride with silver nitrate shows a 1:1 molar ratio between AgNO3 and Cl-: AgNO3 + Cl- -> AgCl + NO3-

In a hress-point testcross, it was found the genetic map for three linked genes was A—20cM—B—10cM—C

If a cross was performed to estimate the map distance between genes A and C only. how would this distance compare to the sum of the distances A-B and B-C? Explain why.

  1. when conducting a thin layer chromatography experiment; Consider 2 hypothetical samples. Sample #1 is weakly adsorbed to the silica gel in the TLC plate and readily dissolves in the developing solvent. Sample #2 is more strongly adsorbed to the silica gel but only moderately dissolves into the developing solvent. Which sample will have a greater Rf and why?

An electric car is designed to run off a bank of 12.0 V batteries with a total energy storage of 2.00 107 J.(a) If the electric motor draws 5.00 kW, what is the current delivered to the motor?(b) If the electric motor draws 5.00 kW as the car moves at a steady speed of 20.0 m/s, how far will the car travel before it is “out of juice”?
