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.

What is JAD and how are users involved? What are advantages and disadvantages of JAD? Joint application development, is a popular fact finding technique that brings users into the development process as active participants. Users have a vital stake in the information system, and should participate fully in the development process. They are/should be involved at every stage of development. Advantages : Users can participate effectively in the requirements modeling stage. More accurate statement of systems requirements, better understanding of common goals and stronger commitment to success of the new project Disadvantages : More expensive, can be cumbersome if the group is too large for the project.

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.)
