Studies of nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all material excreted and eliminated from the body (in urine and feces). Comparing the food to the waste can help determine the specific compounds and elements absorbed and metabolized in the body. The effects of nutrients may only be discernible over an extended period, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of animal nutrition is still slowly evolving.

At which rate is the science behind nutrition continuing to evolve?
Answer: slowly

The official introduction of the metric system in September 1799 was unpopular in large sections of French society. Napoleon's rule greatly aided adoption of the new standard not only across France but also across the French sphere of influence. Napoleon ultimately took a retrograde step in 1812 when he passed legislation to introduce the mesures usuelles (traditional units of measurement) for retail tradea system of measure that resembled the pre-revolutionary units but were based on the kilogram and the metre; for example the livre metrique (metric pound) was 500 g instead of 489.5 gthe value of the livre du roi (the king's pound). Other units of measure were rounded in a similar manner. This however laid the foundations for the definitive introduction of the metric system across Europe in the middle of the 19th century.

How many grams were in the livre du roi?
Answer: 489.5

Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimonincluding Tyrannomon, the first one ever createdwere based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.

Who was the designer responsible for the westernization of Digimon character design?
Answer:
Kenji Watanabe
