The Burgess Shale Fauna/Dinosaur to Bird Fossil Record: Parallels and Contrasts
[ send me this essay ]
An 11 page comparison of the simplicity of the animal species preserved in the Burgess Shale Deposit and the complex evolutionary path recorded in the fossil record for modern-day birds. Discusses the controversy and debate surrounding the question of the speculated origin of birds from dinosaurs. Discusses the current findings in the field and the need for additional research. Paper concludes that not only is there no current connection between the Burgess Shale deposit and the evolutionary path of our modern birds, the theories that connect modern day birds to dinosaurs will undoubtedly continue to be challenged in the future. Emphasizes that research is ongoing, however, and that the probability of identifying a clear and irrefutable association between the dinosaurs and the modern birds is more probable than improbable. Bibliography lists 6 sources.

The Effects of Antibiotics on Bacterial Growth
[ send me this essay ]
A 5 page discussion of bacterial growth in the presence of antibiotics. Examines how bacterial growth is dependent on a number of their physiological mechanisms such as enzymes, proteins, and even the communication of one organism with another in a phenomenon referred to as quorum sensing. Emphasizes that it is critical to continue our quest to understand the specifics of how antibiotics influence bacterial growth. By improving our understanding and concentrating on developing antibiotics which only work on specific intracellular functions of bacteria we have a higher chance of improving the long-term health not only of human populations but also of those populations of plants and animals upon which we depend. Bibliography lists 5 sources.
