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 structures, with large numbers of pre-reproductive individuals. 
2) Population momentum results from large numbers of prereproductive children becoming reproductuve within short period of time.
3) High population rate due to high birth morality rates. 
4) Children viewed as status symbol
5) Resistance to birth control 

Death Rate 
Sweden
1) Elderly survive longer due to advances in medical technology and availabilty.
2) Social welfare programs ensure that elderly are taken care of.

Kenya
1) Elderly do not survive due to lack of available medical technology.
2) Disease (for example, malaria or AIDS) and lack of nutritious food decreases life span

Discuss the seven characteristics of useful information.

Discuss the seven characteristics of useful information. Answer: The seven characteristics of useful information are: relevant, reliable, complete, timely, understandable, verifiable and accessible. These characteristics are qualities that information should possess to be useful in a business environment. Briefly stated, in order for information to be useful it must be: 1) relevant, meaning that it reduces uncertainty and adds to the decision-making process; 2) reliable information is information that is free from error, and is accurate in its nature; 3) complete information is information that does not omit any important data, facts, or aspects about events or activities; 4) information is timely when it is fully available to enable the decision-making process to proceed; 5) understandable information must be both in an intelligible and useful format; 6) information is considered verifiable if two people, acting independently of each other, produce the same inform

Why have accounting software packages been designed with separate transaction modules?

Why have accounting software packages been designed with separate transaction modules? Answer: : Since every organization does not necessarily use all of the transaction cycles in its operations, it is to the advantage of the organization to be able to "pick and choose" from among various software modules that track and record different transaction cycles. For example, a law firm would have no need to implement a production cycle module. Also, the nature of a transaction cycle varies across the broad spectrum of business organizations. Again, a law firm would have a revenue cycle, but it would not involve the purchase, receipt, and payment for products or merchandise; likewise a retail store chain may not sell any consulting services to its customers.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.

A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
