Introduction:

The speciation is the process, through which the different species have evolved from a single ancestor. The speciation occurs when the organism genetic composition is changed according to the environment, they are living in.

Expert Solution & Answer

Explanation of Solution

For the process of speciation, there should be a change in the environment of the members of a single species. The main factor, which can be use to detect the occurrence of the speciation involves the reproductive incompatibility from the previous species.

The three steps of speciation are given below:

1. Divergence: in this step, members of a single species are diverged into different groups. Some of the gene pool of the population become isolated from each other.

2. Evolution of new traits: depending on the environment, the separated gene pool evolves certain characters, which make them genetically different from the species they have evolved.

3. Reproductive incompatibility: due to the changes in the genetic composition, the species cannot mate with the members of the species, from which it has evolved.

Conclusion

The three steps of speciation are, divergence of the members, adaptation and evolution according to the new environment and evolution of reproductive incompatibility.

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
