4.) macroscopic characteristic that can be helpful in bacterial identification include__ a.) colony form b.) colony color c.) gram stain reaction d.) two of these are correct 5.) Some types of media combine multiple tests to inform us of different type of information about an organism. How is this helpful? a.) it makes the biochemical testing process more efficient b.) it allows us to determine the gram reaction without having to do a stain c.) it gives us information about oxygen requirements so we can properly incubate the organism d.) all the above 6.) After preparing a pure culture of the unknown bacterium using an isolation method, the best starting point for the identification process is usually- a.) determination of colony color and form b.) determination of lactose fermentation c.) determination of cell shape and gram reaction d.) determination of specialized structures, such as endospores

For each of the questions, four choices have been provided. Select the correct alternative. Identify the correct sequence of steps in an experiment to show the effect of temperature on the rate of the reaction. (1) Measuring the volumes of $\mathrm{H}_{2}$ gas liberated in the two test tubes. (2) Heating the test tube $\mathrm{B}$ by $10^{\circ} \mathrm{C}$. (3) Comparison of relative volumes of $\mathrm{H}_{2}$ liberated in test tubes $\mathrm{B}$ and $\mathrm{A}$. (4) Addition of same concentration of $\mathrm{HCl}$ to the two test tubes. (5) Taking equal masses of fine granules of zinc in two test tubes $A$ and $B$. (a) $3,4,5,1,2$ (b) $5,4,2,1,3$ (c) $2,1,3,5,4$ (d) $5,4,2,3,1$
