Two weeks ago, you were playing with a guitar at home – an instrument that you have been playing for ten years. Your mother came back from work and began talking to you nonstop. In this case, you were able to hear everything she said. Last night, you were studying for a difficult final exam in philosophy. Your mother gave you the same speech again when she came home, but this time you were not able to hear anything she said. Why was there a big difference in your ability to attend to your mother's speech between the two cases? Explain your answer with a relevant theory

Secretase family of enzymes are central to the processing of amyloid precursor proteins (APP) associated with the development of Alzheimer's disease. They have garnered much attention over the years as a possible therapeutic target for the disease. Would targeting these enzymes for inhibition be an effective strategy for preventing the onset of Alzheimer's related amyloid plaque formation. If not, can you think of another approach that might be effective that doesn't necessarily involve targeting these enzymes?

In a comparative Anatomy lab, you found some bones and the jaws are toothed and that the anterior limbs are modified for flight. Determine whether this tetrapod is related phylogenetically to the subclass Archosauria of the Reptilia, to either the subclass Archaeornithes or the Neornithes of the Aves or to the subclass Eutheria of the Mammalia. Describe those aspects of the fossil which allows you to make your determination. IN OTHER WORDS, WHICH OF THE ABOVE ANIMALS POSSESS THE FEATURE, "jaws are toothed and that the anterior limbs are modified for flight." WHY?
