Pre-Lab #4
1. Two adaptation that are necessary for photosynthetic algae to make the transition from aquatic to terrestrial habitats is that they always need to have moisture, so they will not dry out. Desiccation will cause the terrestrial algae to die out. Another adaptation is that they need a different way to acquire nutrients. Now, they are terrestrial algae, they need a new food source that provides the same nutrients that they acquired from their aquatic habitat.

Table 1 Concentration of protein, DNA, and ratio of the two in heart, kidney and liver of bos taurus. Average standard deviation of protein concentration is also shown.
Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures.
The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.
“Enzymes are proteins that have catalytic functions” [1], “that speed up or slow down reactions”[2], “indispensable to maintenance and activity of life”[1]. They are each very specific, and will only work when a particular substrate fits in their active site. An active site is “a region on the surface of an enzyme where the substrate binds, and where the reaction occurs”[2].
