Overriding 1) You can only move within the object that you have created.2) For all static methods, static variables, instance variables and (instance methods that are not overridden) you get access to the one that is closest to the right of the reference within the object.(Watch out for private members. Same rules apply for private as before. Private members are not inherited and only members within the class have access to it.) (Remember: Overriding pertains only to instance methods that have the same return type, same signature, either default, protected or public visibility modifier, becoming more expansive or remaining the same as you move from parent to the child) 3) If an instance method is overridden then go to the left-most overridden method within the object Abstract classes Abstract classes are incomplete and are therefore non-instantiable. The higher the class is in the class hierarchy, the more abstract its definition. Abstract classes hold common behavior and attributes shared by their subclasses. Abstract classes can contain anything a normal class can Abstract classes can also contain abstract methods. These methods are implemented in subclasses of the abstract class. Abstract methods reside in only abstract classes. Only instance methods can be abstract. An abstract class does not have to contain abstract methods. If an abstract class has nothing but abstract methods, use an interface definition. Interfaces Contain only abstract methods and final static variables final static is implied public is implied for methods and variables Cannot be instantiated An interface can inherit (extends) many other interfaces A class can extend only one other class A class can implement many interfaces Order of execution Order of execution for loading classes and creating objects(Only once when the class is loaded) Static block and variables of the parent 1) Static block and variables of the child (Every time an object is created) 1) Initialization block and variables of parent 2) Constructor of parent (Depends on what happens in the constructor of child. The child constructor will determine how the parent constructor will be called based on either an implicit call or an explicit call using the super keyword.) 3) Initialization block and variables of child 4) Constructor of child

Acid sensing is associated with pain testing, and other biological activities. Acid sensing is carried out by a ligand-gated channel that permits Na+ influx in response to H+. This family of acid-sensitive ion channels (ASICs) includes a number of members. Psalmotoxin 1 (PcTX1), a venom from the tarantula, inhibits some members of this family. The following electrophysiological recording of cells containing several members of the ASIC family were made in the presence of toxin at a concentration of 10 nM. The channels were opened by changing the pH from 7.4 to the indicated values. The PcTX1 was present for a short period of time (indicated by the black bar above the recording below), after which time is was rapidly washed from the system. Which member(s) of the ASIC family -ASIC1a, ASIC1b, ASIC2a, or ASIC3- is/are most sensitive to the toxin? Is the effect of the toxin reversible? Explain. What concentration of PcTX1 yields 50% inhibition of the sensitive channel?
