Answer 2

1. Baking powder is supposed to increase the volume of the bread by releasing Δg in the process of baking, making the dough rise.2. The volume of alcohol in beers is usually measured by alcohol by volume, which refers to the amount of ethanol (in milliliters) contained in 100 milliliters of solution.3. The type of fermentation observed in yeasts is alcoholic fermentation.4. Agrobacterium tumefaciens is a known soil pathogen which causes crown gall disease and is extensively used for genetic transformation in plants.5. Out of the listed options, biscuit is not a fermented milk product and therefore not a dairy product.6. Fermentation is the process where yeast consumes sugar and produces alcohol and carbon dioxide as its metabolites.7. Plasmids are circular, double-stranded DNA molecules typically found in bacteria, and are used as cloning vectors because of their capability to self-replicate in bacterial cells.8. Cheese, curd, and butter are all cow milk derivatives and hence recognized as dairy products.9. Plant Tissue Culture is the technique of growing plant cells, tissues, organs, seeds or other plant parts in a sterile environment on a nutrient medium.10. Decreasing pesticide use pertains to bio-control methods in agriculture biotechnology, where genetically modified plants reduce use of synthetic pesticides.11. In genetic engineering, it is restriction enzymes are used to chop up DNA molecule from a known location.
