How is epithelial tissue the opposite of connective tissue?



Answer: In epithelial tissue the cells are packed together very tightly. Epithelial tissue is avascular. Epithelial tissue has three cell types that cover or line things and make tubes. Epithelial tissue has no fibers and it tends to be polar. Connective tissue has cells spaced far apart and is highly vascular (except cartilage). The cells of connective tissue vary greatly in shape and size. Connective tissue glues other tissues together and has three fiber types. Connective tissue tends to be nonpolar. Connective tissue has a large amount of ground substance; epithelial tissue does not.

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.)
