    The main objective of this lab was to observe the activity of enzyme peroxidase in real time under different experimental conditions. To see how peroxidase reacts with its substrate guaiacol under different conditions. We measure the amount of substances per test tube and then combine all of them together. Each test tube contains a measured amount of any listed substances including H₂O. Each measured amount of peroxidase along with its substrate guaiacol, and other listed substances will show how actively the enzyme oxidizes the substrate. To measure the…

    o Anatomical evidence: (structures of organisms) fossil evidence, homologous structures. Fossils reveal anatomical structures of past organisms and their relationships with living organisms. Homologous structures are structures found in different species that have similar form or configuration due to divergent evolution (common ancestor). The greater the amount of homology between two species, the more closely related they are. Ex) whale cat, gorilla, bat forelimbs(different functions but same bone structures)…

    Lake Malawi’s cichlid male population of fish are tested on their ability to build bowers to attract the female population. Altering this extended phenotype, or ability to build bowers resulted in no change of mating, but males that built successful bowers showed to be less aggressive with other males in the population. This is important in maintaining polymorphic populations (Magalhaes, 2014). In my self-created scenario, the focus is on the small male population of cichlid fish. The male cichlid fish ability to build successful bowers is dominant while not building successful bowers is recessive within the population. After a recent hurricane wiped out the cichlid population food source, the male population has been tested on their ability to find other food for the female population. The ability includes better strength and speed. Female cichlid fish find this new ability to more attractive than building successful bowers because of this environmental change. The purpose of this study is to determine natural selection and to see if the male population of cichlid fish will be altered due to the changes in their environment.…
