Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids (usually from castor bean, but also from soybean oil). In chocolate , compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin [ 2 ] to reduce viscosity .
PGPR that synthesize auxins, gibberellins and kinetins or that interfere with plant ethylene synthesis have been identified. [ 20 ] Development of PGPRs into biofertilisers and biopesticides could be a novel way of increasing crop yield and decreasing disease incidence, [ 21 ] whilst decreasing dependency on chemical pesticides and fertilisers ...
Free response tests are a relatively effective test of higher-level reasoning, as the format requires test-takers to provide more of their reasoning in the answer than multiple choice questions. [4] Students, however, report higher levels of anxiety when taking essay questions as compared to short-response or multiple choice exams. [5]
metal historically used as an anti-microbial. High fructose corn syrup samples were collected from three different manufacturers and analyzed for total mercury. The samples were found to contain levels of mercury ranging from below a detection limit of 0.005 to 0.570 micrograms mercury per gram of high fructose corn syrup. Average daily

Plants respond to pathogens by recruiting PGPR to their root rhizosphere from the bulk soil to fill in and prevent pathogen establishment. This ultimately leads to the development of disease-suppressive soils. PGPR are recruited through the natural release plant exudates from root cells as they push through the soil. [6]
Plants that have been colonized by PGPR forming a biofilm have gained systemic resistances and are primed for defense against pathogens. This means that the genes necessary for the production of proteins that work towards defending the plant against pathogens have been expressed, and the plant has a "stockpile" of compounds to release to fight ...
In countries like the United States and the United Kingdom, essays have become a major part of a formal education in the form of free response questions. Secondary students in these countries are taught structured essay formats to improve their writing skills, and essays are often used by universities in these countries in selecting applicants ...
