Concept explainers
To model:
The evolutionary tree and mention the trunk, branches, and branching points.
Introduction:
The change in characteristics of a species over various generations is termed as the evolution. It is based on the process of natural selection. The theory of evolution says that all species are related to each other and their characteristics change over time.

Explanation of Solution
The evolutionary tree as follows:
The trunk in the evolutionary tree depicts that the way by which an ancestor gives rise various new species due to evolution. The branch point depicts the node. The branches depicts the new species formed after evolution.

- Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…arrow_forwardAnwser these Discussion Questions: Part One Why were the plants kept in the dark prior to the experiment? Why is this important?
