Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that

ABSTRACT: Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactase enzyme. The measurement of light absorbance levels of different solutions based on both the concentration of o-nitrophenol (ONP) as well as the pH of the solution tested. To begin with‚ differing concentrations of ONP were tested to find the absorbance levels of ONP. Three different pH values‚ 5‚ 6‚ and 7‚ in solution‚ were tested over a period of 8
