What type of microscopy would be most appropriate for viewing the following specimens in the following situations? A. To identify pathogenic bacteria in clinical specimens. B. To view objects smaller than 0.2µm, such as viruses. C. To view heat-fixed, stained bacterial cells. D. To view microorganisms that can't be stained by standard methods, such as Treponema pallidum. E. To view internal structures of living microorganisms.

The main limitation of the Bradford Assay is that: Select one or more: a. Only plant proteins can be measured using Bradford dye b. The slope is only linear within a small range of protein concentrations c. This assay can only be used on certain types of proteins d. Proteins can have very different results based on the number of aromatic amino acids they contain e. The spectrophotometer cannot read this assay at the required wavelength

The following experiment was designed to find out to what extent a particular type of fabric gave homogeneous results over its surface for a standard wear test. In a single run the test machine could accommodate four samples of fabric, at positions 1, 2, 3 and 4. On a large sheet of the fabric four areas A, B, C and D were marked out at random at different places over the surface. From each area 4 samples were taken, and the 16 samples thus obtained were compared in the machine with the following results, given in milligrams of wear: run I run II run III run IV position 1 A 26.1 D 20.0 C 32.4 B 20.7 position 2 B 22.3 A 26.9 D 21.5 C 35.0 position 3 C 29.0 B 22.4 A 26.3 D 22.8 position 4 D 30.6 C 28.8 B 25.2 A 26.4 What type of design is this? Analyze the data and draw conclusions.
