Inappropriate number of unit cells used
WebA particle at a corner or on a face or an edge is shared by neighbouring unit cells so in a crystal only a fraction of it belongs to the unit cell in question: A particle at a corner is shared by eight neighbouring unit cells and hence just ⅛ of the particle is within the unit cell. WebJan 3, 2024 · A viable cell count allows one to identify the number of actively growing/dividing cells in a sample. The plate count method or spread plate relies on bacteria growing a colony on a nutrient medium. The colony becomes visible to the naked eye and the number of colonies on a plate can be counted. To be effective, the dilution of the …
