pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds.

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

Individual Project Unit 2 Experiments In this individual project we were asked to conduct three experiments. The three experiments I chose to conduct were Experiment 1‚ Experiment 2‚ and Experiment 4. I have documented my findings for the experiments that were done. In Experiment 1‚ I was to rub my index finger gently over a piece of very coarse sandpaper for a few times. Then‚ I was to rate its coarseness on a scale from 1 (very soft) to 7 (very coarse)
