To be honest, I should know this answer because I am an animal science major, but its been a while since we learned about this stuff. So, from the brief 30 min google search I did:
I can tell you it is almost certainly not "concentrates". Concentrates are usually made of high-energy, low-fiber cereal grains, like oats, corn, soybeans, etc.
Dry Roughage might be the answer just because according to http://modernfarmer.com/2014/12/turnips/, turnips are a diarrhetic for cows. So, they should be mixed with high-fiber feeds in order for the cow to more effectively use of the nutrients in turnips. However, the question asked specifically which feed INCLUDES root vegetables. So, I don't think that dry roughage can possibly be the answer. Dry roughage are high in fiber, low in energy, and usually around 10-15% moisture. Dry Roughages include things like hay, husks, and straw.
Green Roughages is comprised usually contain high moisture content ranging from around 50-90%. I looked it up, turnips are slightly above that range; their moisture content resting at about 91-92%. However other root vegetables did lie in range. Carrots having 88% moistuire, potatos 79%, beet roots 87%, etc. So, I think you could make a case base on the moisture content of root vegetables that they would be found in green roughage.
I do not think it would be Silage because that looks to be a mixture fodder(hay/corn) that has been anaerobically fermented in a silo into a succulent feed.
I think dry matter can't be the answer because I believe it is just a measurement of how much dry matter is contained in a particular feed such as, silages, concentrates, and roughages. For example, this feed mixture is 885 dry matter feed. In conclusion, my best guess would be the answer is GREEN ROUGHAGES just based on the moisture content. Does that make sense to you too? I hope I am correct. I am sorry that I have to guess and that I couldn't tell you a definite answer. I hope this info helped you anyway!
The sea floor is also known as the seabed or the ocean floor. It is made of mafic rocks (crystallized matter from silicate magma) deposits and minerals including basalt, gabbro, olivine, serpentine, peridotite, and ore minerals from VMS (Volcanic Massive Sulfide). Rocks do not have a smooth surface, therefore, the seabed is not smooth and level.
The Pre-Columbian era incorporates all period subdivisions in the history and prehistory of the Americas before the appearance of significant European influences on the American continent, spanning the time of the original settlement in the Upper Paleolithic period to European colonization during the Early Modern period.
While the phrase "pre-Columbian era" literally refers only to the time preceding Christopher Columbus's voyages of 1492, in practice the phrase is usually used to denote the entire history of indigenous Americas cultures until those cultures were exterminated, diminished, or extensively altered by Europeans, even if this happened decades or centuries after Columbus's first landing. For this reason the alternative terms of Precontact Americas, Pre-Colonial Americas or Prehistoric Americas are also in use. In areas of Latin America the term usually used is Pre-Hispanic.
The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter. Another unit of energy you may have come across is the Calorie.
