spec: We try our best to honor each student 's request , but many factors determine the final assignment . Your teacher tells you that if you do not tell , you will get a failing grade on the final . These personal exposure measurements reflect the average magnitude of the magnetic field produced by the various EMF sources and the amount of time the worker spent in the fields . Modern quantum-chemical calculations reveal which mechanism passes the transition state of lowest energy . For example , the gains from virtual endoscopy almost certainly need to take into account the amount of time the surgeon or radiographer spends conducting the inspection . Payne and another teenager play basketball on an outdoor court . There are ecological as well as economic advantages to increasing the amount of time the land is used for production . This is however the only way to collect high signal to noise calibrations , hence special automatic tools have been developed to optimize the number of frames acquired in the short amount of time the sky brightness is within the right range . Such measurements do not necessarily reflect a worker 's personal EMF exposure because they are not always taken at a distance from the source that approximates the worker 's location , they generally do n't account for the amount of time the worker is actually there , and exposure may be different at other times during the day . A single chromosome can only carry a single allele and , except in cases of duplication , deletion or trisomy , an animal carries two autosomal alleles .
