Summary Introduction

To outline:

The major adaptations that emerged during the evolution of vertebrates from fish to amphibians to reptiles to birds and mammals.

Introduction:

Despite the obstacles to life on land, many species represented a tremendous evolutionary opportunity, especially plants. After land plants evolved, providing the potential source of food for other animals, animals emerged from the water (sea, ocean and so on).

Summary Introduction

To explain:

The way in which these adaptations increased the fitness of various groups for life on land.

Introduction:

After land plants evolved, providing the potential source of food for other animals, animals emerged from the water (sea, ocean and so on). The earliest evidence of first land animals comes from 430 million-year-old fossil. The first animals to come onto land were arthropods because they already possessed some specific structures that were suited for the life on land.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
