The process by which anatomical specimens are separated and analyzed in a detailed manner is termed __________.

Bacterial transformations are a useful tool for biologists to replicate valuable plasmid DNA so that it can be used for a myriad of experiments. A student researcher has designed an experiment to determine the effects of pre-incubation duration, heat shock duration, and heat shock temperature on transformation efficiency. The student transformed 1μg of a β**-**lactamase encoding plasmid and recovered the bacteria for 1 hour at 37°C (shaking at 225rpm) for all conditions in Table 1. He then plated the transformed bacteria on ampicillin agar places and observed growth 24 hours later. Table 1 outlines the variables in the experiment.

If the student researcher had also done trials with a heat shock temperature of 36°C, the resulting transformation yield would most likely be __________.

If the student realizes that a fraction of the ampicillin agar plates he used to select for transformed bacteria had expired, which conditions would most likely have been grown on expired ampicillin?
