This chapter discusses the different types of research design and you have read about them as well. For this entry, conduct a PubMed search and find two abstracts of studies both using a cross sectional design. The abstracts may be on any topic you chose-and they do not all have to be on the same topic. In your post, include each abstract and write about the distinguishing factors of the design used, and comment on whether or not you feel there was any other way this study could have been designed. In addition comment on next steps for the topic given the findings.

Question: Some bacteria have Lipopolysacchride (LPS) in their envelopes. In the case of sepsis, microbial death and lysis results in release of massive amounts of endotoxin into the circulation resulting in toxic shock syndrome. Do some research and answer the following questions:
Where specifically is LPS found in the bacteria?
Do all types of bacteria have LPS in their envelopes?
What is the chemical makeup of the LPS?
Look up Toxic Shock Syndrome. What is its effect on your physiology?
Which portion of the LPS causes toxic shock syndrome? What is endotoxin?

Propose a new 'enzyme exercise' which could be adapted to online learning (i.e, perhaps an experiment that can be conducted in the kitchen). The experiment teaches the main concepts about enzymes and you describe an experiment with independent and dependent variables and controls. Feel free to submit something you found online and suggest modifications. Make sure to reference your sources. You may use your lab manual as a reference.
