the substance was an acid. If it turns a greenish color it base. If it stays about the same, it is neutral. Also acids and bases can react to one another turning neutral. There is a whole color scale you can use to determine the exact ...
Watch for bubbles. If it bubbles, the candy is acidic. What's happening: When you dissolve acidic candy in water and add baking soda, the reaction produces carbon dioxide gas. This is what makes the bubbles. For more fun, try testing candy like Skittles, StarBursts, or Sweet Tarts. Do ...
We thank the anonymous reviewers for their insightful suggestions and K. Young for assistance with circular dichroism experiments. Work in our laboratories is supported by fellowships from the National Health and Medical Research Council (APP1154646, to A.F., and APP1154932, to O.R.) and an ...
proteins. Biochemical experiments using recombinant TgLEA proteins, performed in vitro, show cryoprotective action on the oocyst-associated lactate dehydrogenase enzyme. Cold stress-induced survival was improved by the expression of two of these proteins in E. coli. The knockout of all four LEA ...
