In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

1. What do you think is the major problem with the performance appraisal process in the regional office? In my opinion‚ the major problem with the performance appraisal process is that employees aren’t being told how they need to improve after the appraisal is conducted‚ therefore each year the appraisal more or less stays the same. The appraisal is supposed to be used to improve the employees performance‚ however it is not being used to do so. No feedback is given to the employee after the appraisal
