Chapter 1.4, Problem 13RQ

Selection of Traits What adaptations do scavengers have for locating and feeding on prey? What adaptations do predators have for capturing and consuming prey?

Competition Between Species What natural processes limit populations from growing too large?  What are some resources organisms can compete over in their natural habitat?

Species Interactions  Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.

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 is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?

What are coupled transporters?

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

What are intrinsically disordered proteins, and how might they be useful for a living system?

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