Article: Although not yet tested as a therapy in humans, a growing body of evidence indicates that zinc may preferentially kill prostate cancer cells. Because zinc naturally homes to the prostate and because the prostate is accessible with relatively non-invasive procedures, its potential as a chemotherapeutic agent in this type of cancer has shown promise. However, other studies have demonstrated that chronic use of zinc supplements in excess of the recommended dosage may actually increase the chance of developing prostate cancer, also likely due to the natural buildup of this heavy metal in the prostate.

Question: Where does zinc naturally buildup in the body?
Ans: prostate.


Here is a question about this article: The Qing dynasty was founded not by Han Chinese, who constitute the majority of the Chinese population, but by a sedentary farming people known as the Jurchen, a Tungusic people who lived around the region now comprising the Chinese provinces of Jilin and Heilongjiang. The Manchus are sometimes mistaken for a nomadic people, which they were not. What was to become the Manchu state was founded by Nurhaci, the chieftain of a minor Jurchen tribe – the Aisin Gioro – in Jianzhou in the early 17th century. Originally a vassal of the Ming emperors, Nurhachi embarked on an intertribal feud in 1582 that escalated into a campaign to unify the nearby tribes. By 1616, he had sufficiently consolidated Jianzhou so as to be able to proclaim himself Khan of the Great Jin in reference to the previous Jurchen dynasty.
What is the answer to this question: What type of lifestyle did the Jurchen live?
****
So... sedentary farming


The problem: Answer a question about this article:
Drug discovery is the process by which potential drugs are discovered or designed. In the past most drugs have been discovered either by isolating the active ingredient from traditional remedies or by serendipitous discovery. Modern biotechnology often focuses on understanding the metabolic pathways related to a disease state or pathogen, and manipulating these pathways using molecular biology or biochemistry. A great deal of early-stage drug discovery has traditionally been carried out by universities and research institutions.
What is involved in drug discovery?
****
The answer: isolating the active ingredient from traditional remedies or by serendipitous discovery
