Summary Introduction

To determine:

The reason that the mammalian and reptilian diversity are present so low on the islands.

Introduction:

Biodiversity is termed as the measurement of variation at the genetic, species, and ecosystem level. It is variability within living organisms from all sources. It increases the stability and resilience of the ecosystem.

Island biogeography determines many factors which are affecting the species of the communities that are isolated. The given theory of island biogeography shows the entire number of species which are can survive on an island. These numbers are the result of measuring extinction and immigration.

Expert Solution & Answer

Explanation of Solution

Many factors can influence the biodiversity of an island. However, they may lead to reduce the diversity of an island. Human activities are the major key factors that can disrupt the biodiversity of an island. Human activities such as hunting play a role in animal extinction. For example: dodo is a bird that was a predominant species presenting on an island of Mauritius. Due to the human hunting and predators, the species got extinct.

Habitat destruction is a factor that can well define the low biodiversity of reptiles and mammals. Natural resources that are essential for the survival of species, when depleted led to the decline in the number of populations. Some major factors such as deforestation, pollution, and over exploitation cause a decline in natural resources and affect the biodiversity on islands in an indirect way.

Smaller animals get fed by predators on the island. Due to the imbalance between higher and smaller animals, biodiversity gets affected on the islands. Trophic cascades and global warming are also responsible for the low numbers of animals on the island. This affects the numbers of mammals and reptiles on the island.

Conclusion

All the factors given above can cause a low diversity of mammals and reptiles on the islands.

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),…
