    Results: The mealworms that were in the room temperature water have a higher cellular respiration rate than the mealworms in the cold water. This is because while they are in the cold water‚ the mealworm’s body slows down which decreases the amount of CO2 that is being produced. Unlike the mealworms in room temperature water‚ their cellular respiration was higher because their body temperature remained the same creating CO2 at a faster rate. Since there were two different controlled groups‚ there

    particles in the compound are excluded from the crystal lattice. After obtaining the pure compound‚ a melting point determination procedure can be done using a mel-temp device to correctly identify the compound if its identity is unknown. In this experiment‚ the identity of a given unknown organic solid will be discovered using the methods of recrystallization and melting point determination.

    9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their
