Scientists are diligently looking for other genes that may be involved in ALS, but currently, there is no other genetic test that will identify ALS in families. Therefore, the determination that an individual has the inherited type of ALS is typically based on family history rather than a genetic test.
Jakub Krystof Rad invented the first sugar cubes in the 1840s at a sugar refining plant in Dacice, a small Moravian town in what is now the Czech Republic. These early cubes were made primarily of beet sugar, and in modern times, either beet or cane sugar is considered acceptable.
You can figure this out. Determine the molecular weight of glucose- that is the weight in grams of 6.02x10^23 molecules (one mole of glucose). Then weigh one sugar cube- that is the weight of your unknown number of molecules. Divide your sugar cube weight by the molecular weight- that gives you the percentage of a mole that your sugar cube contains.
