Animal Development and Heritable Traits Lab Report
Animal Development and Heritable Traits Lab Report Introduction Drosophila, or the fruit fly, is an ideal organism for many laboratory studies. It can easily be observed in a confined space and two flies can reproduce hundreds of offspring. The most important thing about studying fruit flies, however, is the ease with which inherited traits can be observed in them. Heritable traits are those that are expressed in organisms due to genes passed down to them

Physics Lab Report
ABSTRACT The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2, which is consistent
