When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

fracţionare ghidată/dirijată de activitate/activitatea biologică
Am găsit o explicaţie care cred că se potriveşte metodei respective
Once a potentially interesting extract is identified, the scientists employ a process called "bioassay-guided fractionation" to lead them to the active compound.This starts with the extraction of an entire marine organism. The next step is a fractionation process, which results in a number of different fractions from the original extract. Each fraction then undergoes a bioassay to determine if it has any effect on whatever biological material (cells, tissues, etc.) is being tested. If it does, it is then fractionated further and bioassayed again. The fractionation and bioassay process goes on until a pure active compound is discovered.

aici cred că este vorba mai mult de activitatea biologică a extractelor, nu chimică, desigur intervine în procesele biochimice, dar nu este pur chimică
