A summary of the physical properties of poloxamers follows, with the emphasis on those properties most relevant to commercial applications. An extensive review (277 references) [4] provides a wealth of specific exam-... 

Overdose History, physical exam Drug specific... 

Evaluate patient history and physical exam findings and recommend a specific regimen including both pharmacologic and nonpharmacologic therapy. 

The other nine amino acids are essential and must be taken from the diet. Notice that some of the amino acids require other amino acids for their synthesis. Exam questions usually center on whether or not an amino acid is essential and the metabolites that serve as precursors for specific amino acids. 

A major way to control enzyme activity is the reversible phosphorylation of serine or threonine residues. It s such a major way to regulate enzymes that you will spend much of your time trying to remember whether or not enzyme X is activated or inactivated by phosphorylation, and you will invariably forget one or two of them on the exam. By remembering a couple of generalities,2 you can actually figure out a lot of the effects of phosphorylation on specific enzymes without really memorizing them. 

To find out about a specific policy for the AP exam(s) you plan to take, write to the college s Director of Admissions. You should receive a written reply telling you how much credit and/or advanced placement you will receive for a given grade on an AP Exam, including any courses you will be allowed to enter. 

In the second section of the AP exam, you should begin all questions by numbering your answer. You do not need to work the questions in order. However, the graders must be able to identify quickly which question you are answering. You may wish to underline any key words or key concepts in your answer. Do not underline too much, however, because doing so may obscure your reasons for underlining. In free-response questions that require specific calculations or the determination of products, you may also want to underline or draw a box around your final answer(s). 

No attempt is made here to combine your specific results on the practice AP chemistry free-response questions (Section II) with your multiple-choice results (which is beyond the scope of this book). However, you should have your AP chemistry instructor review your essays before you take the AP exam so that he or she can give you additional pointers. 

Over the years there has been an observable trend indicating the number of points required to achieve a specific grade. Data released from a particular AP Chemistry exam shows that the approximate range for the five different scores (this changes from year to year—just use this as an approximate guideline) is as follows ... 

This approach is for students who have already studied most of the material that may be on the exam. The best use of this book for you is as a specific guide towards the AP Chemistry exam. There are time constraints to this approach, as the exam is only a short time away. This is not the best time to try to learn new material. 

Notice that all the answers are very short. Do not try to fill all the space provided on the exam. You score points by saying specific things, not by the bulk of material. The graders look for certain keywords or phrases. The answers should not contain statements that contradict each other. 

The authors hope that, because you are preparing to take the AP exam, you have already been exposed to the balancing of chemical equations. We will quickly review this topic and point out some specific aspects of balancing equations as the different types of chemical reactions are discussed. 

No specific keywords or equations are listed on the AP exam for this topic. 

You calculate the change in temperature from your measured initial and final temperatures. You do not need to give a lot of detail when listing the required measurements, but you need to be very specific in what you measure. Many students, have lost exam points for not clearly distinguishing between measured and calculated values. 

The specific information present in a PSSM, even when it is made from only two or three homologous sequences, particularly favors the similarity between the sequences aligned to compute it and can improve searching sensitivity dramatically. This is because constraints on each position in a multiple alignment become better defined as more exam-... 

Of course, no book can cover every type of problem you may face on a given test. But this book is not just about recognizing specific problem types it is also about building the essential skills, confidence, and processes that will ensure success when you are faced with a math problem. The math topics in this book have been carefully chosen to reflect not only what you are likely to see on an exam, but also what you are likely to come across regularly in books, newspapers, lectures, and other daily activities. 

On an organic chemistry exam, if the instructor takes time to draw the specific stereochemistry of a molecule, it s a hint that you should carefully consider the stereochemistry of any reactions you use.
