Chapter 1, Problem 1FIB
Summary Introduction

Introduction:

The organism is an individual body that shows the properties of life. Organisms are classified into a specific group on the basis of their physical appearances as well as on the function. Some organisms are single-celled and some are a complex multicellular organism. Organisms interact with the environment for their survival. They do adapt new feature for the betterment of their life.

Answer to Problem 1FIB

Correct answer:

Organisms respond to stimuli. Organisms acquire and use energy and materials from the environment. Organisms are composed of cells whose structure is both complex and organized. Collectively, organisms evolve over time.

Explanation of Solution

Organisms are the living creature that will respond to every external stimulus. They are either unicellular or multicellular; generally lower animals like bacteria are unicellular. Humans and animals are multicellular because they have specific cells for a specific function.

Each and every organism required energy and material for their survival from the environment. The environment provides food (energy source) and other abiotic components like oxygen (for breathing) to organisms.

Organisms are evolving over time because of high competition and natural selection. If they will not evolve themselves than they will extinct soon because of a highly evolved organism who will act as a predator for them.

Conclusion

Organisms are the creature that shows properties of life such as evolution, the response to stimuli, interaction with the environment, and different in their structural complexity.

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
