另外，营养生物标记可提供较多的客观膳食评估，并有助于鉴别出患长期BP升高和偶然性高血压的最高风险个体患者。
Further, nutritional biomarkers may provide a more objective dietary assessment and help identify individuals at greatest risk for long-term BP increases and incident hypertension.
在完全黑暗的条件下，根本无法进行光合作用，但绝大多数光养生物都通过依赖混合营养体的营养循环生存了下来。
No photosynthesis could take place under the complete darkness, but the phototrophs mostly managed to survive based on nutrients cycled by the active mixotrophs.
琼斯和他的同事们还想研究混合营养体与光养生物或依赖阳光生长的生物共同生长时的表现。
However, Jones and her colleagues also wanted to see how mixotrophs fared when living together with phototrophs, or light-dependent organisms.
这可能是因为光养生物为了在弱光条件下进行光合作用而消耗了太多的能量，也可能是由于饥饿的混合营养体将光养生物都当成了食物。
The phototrophs may have used too much energy trying to do photosynthesis in the weak light, or perhaps the hungry mixotrophs simply fed on their fellow organisms.
因此他们检测了混合营养体与光养生物分别及共同培养于不同光照条件下的生长情况。
