Problem: Genomes are more than the sum of an organism's genes and have traits that may be measured and studied without reference to the details of any particular genes and their products. Researchers compare traits such as chromosome number (karyotype), genome size, gene order, codon usage bias, and GC-content to determine what mechanisms could have produced the great variety of genomes that exist today (for recent overviews, see Brown 2002; Saccone and Pesole 2003; Benfey and Protopapas 2004; Gibson and Muse 2004; Reese 2004; Gregory 2005).
What does GC-content have that can be measured?

Answer: unanswerable


Problem: The macronutrients are carbohydrates, fats, protein, and water. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories (often called "Calories" and written with a capital C to distinguish them from little 'c' calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram, though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons.
What other significant aspect do macronutrients provide other than energy?

Answer: structural material


Problem: The University of the Republic is the country's largest and most important university, with a student body of 81,774, according to the census of 2007. It was founded on 18 July 1849 in Montevideo, where most of its buildings and facilities are still located. Its current Rector is Dr. Rodrigo Arocena. The university houses 14 faculties (departments) and various institutes and schools. Many eminent Uruguayans have graduated from this university, including Carlos Vaz Ferreira, José Luis Massera, Gabriel Paternain, Mario Wschebor, Roman Fresnedo Siri, Carlos Ott and Eladio Dieste
