5. Refer to Dry Lab 4.B. Describe the technique used to test for the completeness of the precipitation of an ion.
1. Briefly describe the aseptic technique used in lab to prevent contamination of cultures (tubes and plates). True or False: 1. All extremophile bacteria are sensitive to UV irradiation. 2. Deinococcus radiodurans have multiple genome copies and very efficient UV repair systems. 3. The purpose of endospores is to allow bacterial reproduction. 4. The decolorizer agent in the endospore stain is water.
A solution is known to contain Bi3+ ion or Cd2+ ion or both. Describe the test(s) that could be used to separate and identify these ions. Describe the results you would expect to see for each ion, if that ion was present.

5 Traditional lab equivalent instrument used for test hemoglobin, not the portable hemoglobinmeter used for the point of care! Name the fixed, Central Lab-based instrument (and manufacturer) that measures the hemoglobin. Any particular reason for choosing this instrument?
2. (a) Briefly describe the compiler-based register optimization technique (typically (4 marks) (b) Describe the delayed branch technique and explain why it is more common in (4 marks) tetch, indirect and moon used for RISC machines). (c) Show the pipeline activity for the following code fragment with and without applying the delayed branch technique. Assume that there are three pipeline stages (fetch-decode, address calculation, data movement) for load and store RISC machines than in superscalar processors. instructions and two stages...

The membrane filter technique was used to test a polluted water for the coliform group. Three different water sample volumes (5 ml, 50 ml, and 500 ml) were filtered through five filter membranes. The colony counts were as follows: 5 ml membranes: 4, 8, 5, 2, 3 50 ml membranes: 24, 38, 25, 32, 30 500 ml membranes: 250, 320, 360, 210, 280 a. What are the most valid data obtained? b. Calculate the...
