| Which of the following is NOT an important way that Vorderman extended Eijkman's earlier studies? He tested humans. He investigated the same main factor, only with more individuals. He compared diets of polished rice and unpolished rice under relatively similar conditions. He showed that many possible factors related to bacterial transmission were not correlated with the occurence of beriberi. Which of the following interpretations about the cause of beriberi does NOT fit with Vorderman's findings? The rice mills were unsanitary and introduced bacteria into the rice as it was polished. A diet of primarily polished rice lacked an important nutrient found in the cuticle of the rice. Beriberi was contagioius. A bacterium in the starchy part of the rice produced a neurotoxin. |
