Context and question: One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.
What does the bacteria give the worm?
Answer: nutrition
Context and question: At the time of this entry, we were not able to identify any specific nutrition literacy studies in the U.S. at a national level. However, the findings of the 2003 National Assessment of Adult Literacy (NAAL) provide a basis upon which to frame the nutrition literacy problem in the U.S. NAAL introduced the first ever measure of "the degree to which individuals have the capacity to obtain, process and understand basic health information and services needed to make appropriate health decisions" an objective of Healthy People 2010 and of which nutrition literacy might be considered an important subset. On a scale of below basic, basic, intermediate and proficient, NAAL found 13 percent of adult Americans have proficient health literacy, 44% have intermediate literacy, 29 percent have basic literacy and 14 percent have below basic health literacy. The study found that health literacy increases with education and people living below the level of poverty have lower health literacy than those above it.
In which country were there no specific nutritional literacy studies on a national level that could be found?
Answer: U.S.
Context and question: Mary is also depicted as being present among the women at the crucifixion during the crucifixion standing near "the disciple whom Jesus loved" along with Mary of Clopas and Mary Magdalene,[Jn 19:25-26] to which list Matthew 27:56 adds "the mother of the sons of Zebedee", presumably the Salome mentioned in Mark 15:40. This representation is called a Stabat Mater. While not recorded in the Gospel accounts, Mary cradling the dead body of her son is a common motif in art, called a "pieta" or "pity".
What does pieta mean?
Answer:
pity
