Provide a reason why an instance data would be declared static. 

Answer:  If an instance data is to be shared among all objects of the class, the instance data would be static.  As an example, an instance data that counts the number of times something has happened across all objects of the class would be made static.  If we are writing a chess game and have a ChessPiece class that includes a method called movePiece, we would want to know how many moves a player has made, but not necessarily how many times a single piece has been moved.  So, all of the ChessPieces share a numberOfTimesMoved instance data that is incremented by any ChessPiece whenever it is moved.

In any organization, employees rely on the grapevine, particularly during times of uncertainty. The grapevine is an unstructured and informal network founded on social relationships rather than organizational charts or job descriptions. Although early research identified several unique features of the grapevine, some of these features may be changing as the Internet plays an increasing role in grapevine communication.

Examine the age-structure diagrams of Sweden and Kenya below, and answer the following questions.   Compare and contrast the two age structure diagrams in terms of two population dynamics - birth rate and death rate. Restatement: Given two age-structure diagram, Sweden and Kenya for 2000, compare and contrast the diagram in terms of population dynamics.  Age structure diagrams are basically divided into three major age categories: 1) Prereproduction (0-15 years old) 2) Reproductive (16-45 years old) 3) Postreproduction (46 years old-death) Birth Rate Sweden  1) Population has nearly equal proportions of pre-reproductive and reproductive individuals. 2) Little growth over a long period of time will produce a population with about equal numbers of people in all age groups. 3) Children not required or necessary to support parents.  4) Availability and acceptance of birth control. Kenya 1) Population had pyramid-shaped age structu...
