See below for an image from the Old Farmer's Almanac of thebeet (Beta vulgaris), a root vegetable. Credit: Darasp Kran/Shutterstock.Each beet cell has a large central vacuole that stores betacyanin, a reddish pigment. The membrane thatserves as the boundary for the vacuole is called the tonoplast and it, like the plasma membrane, issensitive to damage when exposed to varied environmental conditions. Credit: Slideserve.com.Beetroot cell vacuolesThe results below were obtained after exposure of beet root cylinders to varied temperatures andorganic solvents. This was done to assess the impact of physical and chemical factors on the integrity ofthe cellular membranes.Results (From Pockat AP Biology)TEMPERATURE EXPOSURES: Six different temperatures were used (°C) and the color scale representssubjective assessments with 0 being no color and 5 being intense coloration (red).Beets Samples (ColorIntensity)Tube # Treatment17025513402056-55Temperature Variant: BeetMembrane DisruptionI BeetsI J4.51.5705540205 -5Temperature Treated

Prove if the statement is TRUE or False with complete solution. At a dilution factor of, UHT-pasteurized milk sample X yielded the following bacterial colony counts when spread-plated in quadruplicates: 23, 20, 35, and 41 CFU/plate. As a result, the milk sample will pass laboratory standards if the total microbial limit is set to "not to exceed 30,000 CFU/mL of milk sample."

Separation of Amino Acids by Thin Layer Chromatography Lab Questions 1. Describe in detail Thin layer chromatographic experiment. Example: the theory behind it, how youwould prepare the materials to spot on the plate with different mobile amino acids and unknown andhow TLC Plate is developed and the reasoning behind which solvent/ solvent mixture should be used,along how to correctly identify of the unknown. 2. Calculate the Rf value if a solute travelled 5 cm from the base spot and the solvent front is 10 cmfrom the origin? 3. In a TLC experiment using a 70:30 mixture of Petroleum ether and ethyl acetate, a student noted thedevelopment of spots in the origin, what can you suggest about this observation?
