Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of

Who normally conducts the preliminary investigation? What are some of the actions the first responders can take once they arrive at the scene of the crime? Since the preliminary investigation starts when the first emergency call is received‚ it is typically administered by the patrol officers who are first to respond to the scene. First responders can either preserve or contaminate the crime scene‚ which can possibly result in either the success or failure of the prosecution. Accordingly‚ the steps
