Tryptic Soy Agar contains digests of soybean meal and casein, making it suitable for the growth of a wide variety of fastidious and nonfastidious microorganisms.(2-6, 8) The combination of soy and casein peptones supply organic nitrogen in the form of amino acids and polypeptides, making the medium highly nutritious. Sodium chloride is added to maintain the osmotic equilibrium. Products containing additional salt (Cat. nos. Q90, Q91, and Q92) are recommended for use in determining the halotolerance levels of microorganisms. Agar is the solidifying agent
A small cell is more efficient, when the materials enter the cell, they are more evenly distributed compared to a larger cell.
6. pegmatitic (a pegmatite is a very coarse-grained intrusive igneous )
rock
7. shallow sea (limestone is the most common cemical sed rock, and they are most commonly in shallow marine environments)
8. sunlight (wind, water and ice are the primary mechanisms for the breakdown and transport of rocks and their erosional products)
9. addition of heat and pressure (heat through contact metamorphism with an igneous mass or by compression and deep burial, and pressure through tectonic forces)
10. a different metamorphic rock (this sounds like a trick question. The use of "additional pressure" implies that pressure has already been applied, in which case a metamorphic rock has already formed. Therefore, a "different metamorphic rock" will result)
11. stratification (strata are sedimentary layers)
12. sedimentary (a conglomerate)
13. extrusive (lavas have formed by "extrusion" from a volcanic edifice
14. organic (includes coal and limestone)
15. it will fizz in acid. (marble still is made up of calcium carbonate, which is the chemical which reacts with acid and fizzes)
