Imagine you want to learn more about Mike Smith’s osteosarcoma. How could you use microarray technology to determine which genes have been affected in his tumor cells? What does it tell us if two genes show the same levels of expression in cancer cells and normal cells? What does it tell us if there are some genes that are highly expressed in normal cells but not expressed in cancer cells? What can a DNA microarray teach us about oncogenes and tumor suppressor genes? Use the information you learned from the DNA microarray to write an argument to convince smokers to stop smoking. Be sure to reference any differences you saw in gene expression in smokers and nonsmokers studied in the experiment.

Explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
