magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America.  The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind.  Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.  (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).

What are coupled transporters?

What are “domains” and how do they aid in protein function?

What are Amyloid Fibrils? What biological functions are these known to perform?

How do histamine and prostaglandins help in the mobilization of leukocytes to an injury site? What are chemotactic factors? How do they affect inflammation process?
