When there is insufficient research to determine the rda for a nutrient, the ______, based on estimates of intakes that appear t
o maintain a defined nutritional state in a specific life stage, is the nutrient standard. daily value (dv) adequate intake (ai) estimated average requirement (ear) tolerable upper intake level (ul)?
It is a recommended intake value that given based on experimentally determined approximation or the estimates of the nutrients intake by a group of healthy people.
It becomes an important guide in the absence of enough scientific evidence in order to establish an estimated average requirement. Adequate intake of a nutrient is determined after a lot of observation and research.
Hence, the correct answer would be Adequate intake.
When the RDA research is inadequate or by any means the RDA cannot be determined for any nutrient, then the adequate intake value is preferred.
Adequate intake value is defined as the average level of nutrient (belonging to a particular group) that must be taken depending upon observed values or approximations deduced through experiments for apparently healthy people.
Chargaff's rules state that "DNA from any cell of any organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine".
