Four individuals are suspects in a car theft. A small amount of blood was left in the car, likely from when the thief forced the window. The blood sample was amplified and compared to samples from the suspects. Lanes I, II, III, and IV are the samples from the four individuals. The lane marked "evidence" is the sample from the car. I II III IV Evidence - Which suspects, if any, can be eliminated? II and III II and IV I and IV I, III, and IV I and III I, II, and III Incorrect

The organic lab program generates around 200 liters of non-halogenated organic waste every week. A student accidentally added some halogenated organic waste to a waste container that entered the non-halogenated waste stream.  The cost to dispose of 1.000 liter of non-halogenated organic waste is $20.27  The cost to dispose of 1.000 liter of halogenated organic waste is $89.71 Due to the error, how much extra money will it cost to dispose of 210.9 liters of the waste that week?

A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.07750.0775 L sample, the chemist measures 327327 μg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: _____ ppmppm concentration: _____ppb

This is my 2nd attempt to receive help with this problem. The previous expert confused me by saying the answer is less than 109.5? Does that mean it should be 90?  Please provide clarity instead of adding confusion; otherwise the payer loses a question for assistance.  Thank you.

10 ut of Compute the amount of medication that will be given to administer one dose of the following medication orders. Round all parenteral administration orders that are over 1 mL to one decimal place. Round all parenteral administration orders under 1 mL to two decimal places. Do not include zeros at the end of decimal numbers. The problems and drug orders are presented for practice only, and actual prescribed dosages will vary according to a patient's age, condition, reaction, additional medications, and other factors.

2. Using Excel, make a graph of the following data. Plot Mass vs. Volume for the following data on the same graph. Use a linear fit of each set of data and include the equation of the best fit line (2 fits and 2 equations, making sure you can tell which equation is for which set of data). Submit your graph and answer the three questions below. Volume (ml) 5.00 10.00 15.00 20.00 30.00 Mass of Al (g) 43.195 56.053 70.961 82.499 108.988 Mass of Zr (g) 63.797 94.708 127.933 158.580 227.037 For both straight lines, the slope is essentially equal to the density of the element. The y-intercept is equal to the mass of the beaker that held the substance. Answer the following questions. a) For each element, what is the density (slope)? What is the mass of the beaker (y-intercept)? Be sure to include units. b) If you have 120.000 g of Al and beaker, what is the volume? 21.⁰ c) When the volume of Zr is 25.00 mL, what is the mass?

The market supply of lettuce in a small town is shown in the table below. Supply of Lettuce Price (dollars per Quantity of Lettuce Supplied (heads) head) Initial New $4.00 400 3.50 300 3.00 200 2.50 100 Instructions: Enter your answers as a whole number. a. Suppose an increase in the cost of water decreases production of lettuce heads by 30% at every price. Complete the new supply schedule in the table above. b. At a price of $3.50 per head of lettuce, the original quantity supplied was heads of lettuce and the new quantity supplied is heads of lettuce.

A group of students performed a melting point experiment to study the physical properties of ionic and covalent solids. The data collected are shown in the table.  Solid Sample Melting Point (oC)  Time Elapsed (min) Table Sugar (sucrose) 186 18 Table Salt (sodium chloride) 500 (not observed) 30  Paraffin Wax 37 4  Vegetable Lard 50 >5 Using the information contained in the table, what is the BEST explanation for the results?A    The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B    The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C    The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…

Ms. Tan came to the laboratory for blood tests because her physician suspected renal disease. The tests ordered were serum BUN, creatinine, and electrolytes. The blood specimen was obtained and processed. When the laboratory scientist received the serum to perform the tests, he noticed that the serum had a reddish tinge. What factor/s could cause this to happen to a serum specimen?     2. Is the sample acceptable for use? Elaborate your answer   3. What are the advantages of using plasma compared to serum in chemical analyses?
