I wasn't aware that it was, but I would assume it is because the particles of flour are finer and pack together tighter.

Yes, although it will make the cake more dense.
A cup is a measure of volume, and ounces are measures of weight. A cup of a more dense (therefore heavier by volume) material like cheese will weigh more than a cup of a less dense material like flour.
Whole grain bagels are considered to be more nutrient dense. Plain bagels are less nutrient dense. The reason for this is because plain bagels have refined flour and sugar in them.
Yes, but be careful when using it. Many people say that it's more dense than white flour and will alter a recipe. Others say that white spelt, specifically, is actually lighter.
Grinding a grain cause the complex geometry/texture of the large original pieces to simplify, as well as breaking up internal gaps, allowing the small particles produced to fit together far more compactly than in the original structure -- and thus the flour is dense.
Generally the same amount. Might sift all purpose 1 0r 2 times to create more air since wheat flour is more dense. Mix all purpose flour as little as possible to avoid glutens which could toughen final product.

One must expect some differences in the final product when whole wheat flour is substituted for white or all-purpose flour. A fairly safe practice is to replace no more than one-third of the flour with whole wheat flour. This ensures proper rising and a delicate crumb. As the proportion of whole wheat to white increases, the baked product will be increasingly dense with less rise and a tougher, more chewy crumb.
