Effective reading of the Results and Discussion section involves identifying its structure and extracting relevant information. Read the following statements, and identify the information contained in these three parts, and match the statement of a, b, &c with1, 2, & 3 1. Limitations and how they were addressed 2. Key findings 3. Main results a. Consumption of black tea without milk caused nausea in three volunteers. (the 2nd sentence of Results) ———————— b. We found that severely obese subjects with a high prevalence of diabetes and the metabolic syndrome lost more weight in a six-month period on a carbohydrate-restricted diet than on a fat- and calorie-restricted diet (the 1st sentence of discussion) ———————— c. This study proves a principle and does not provide clinical guidance; given the known benefits of fat restriction, future studies evaluating long-term cardiovascular outcomes are needed before a carbohydrate-restricted diet can be endorsed (the last sentence of paragraph 7, Discussion) (填空格式:例如123)
A、The definition and inclusion for essential element are not the same in plant and animal systems.
B、Because the trace elements essential for plants are those elements which cannot be substituted by others in their specific biochemical roles and that have a direct influence on the organism so that it can neither grow nor complete some metabolic cycle.
C、In general, B, Co, Cu, Fe, Mn, Mo, Si and Zn are known to be essential for plants, whilst Al, As, Br, F, I, Li, Ni, Rb, Se, Sr, Ti and V are known to be essential for some groups or species. In human and animal systems, trace elements are defined as being essential if depletion consistently results in a deficiency syndrome and repletion specifically reverses the abnormalities.
D、The trace elements fulfilling these requirements are As, Co, Cr, Cu, F, Fe, I, Mn, Mo, Ni, Se, Si, Sn, V and Zn.
A、nutrients
B、non-nutrients
C、water soluble substance
D、metabolic intermediate
