Answer:
The correct answer is option C. "arg+leu– or arg–leu+".
Explanation:
This bacteria is not able to growth on minimal medium or minimal medium supplemented with leucine. This means that the bacteria needs external supplementation of amino acids to growth, either arginine or leucine. Therefore, this bacteria can have the genotypes of arg+leu– or arg–leu+, meaning that the bacteria is able to synthesize either of two amino acids, but not both, because if that was the case the bacteria would be able to growth on minimal medium.
Answer:
Internal Cycling
Explanation:
Internal cycling starts when the nutrients transform into ecosystems. The plants through their roots take the necessary ingredients and built them in the tissues. When tissues grow, the nutrients go back to the ground in the form of dead organic matter.
Microbes transform the organic nutrients into minerals, which are again available to the plants.
The right option is Intolerance
Drug Intolerance is a situation
in which drugs cause adverse effects such as drowsiness or stomach upset and
the body is unable to tolerate or bear these effects. An individual with drug
intolerance may be able to continue with the drugs if the dose is reduced
because drug intolerance sometimes disappears as drug therapy continues.
