How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚

adaptations which help populations survive‚ and mutations generate the variation needed by natural selection. 4. What are the goals of taxonomy? The goals of taxonomy are to name species and classify them based on evolutionary relationships. 5. List and describe the four main groups of eukaryote. Plants – multicellular‚ photosynthetic life‚ producers‚ autotrophs Animals – multicellular‚ no photosynthesis and independently mobile‚ consumers‚ heterotrophs Protista – multi- or single- celled

Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple
