Solution
A urine sample of a patient, tested with Benedict/Fehling solution, gave an orange colored precipitate,
indicating the presence of
A
glucose
B
sucrose
C
lactose
D
maltose
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Though the Benedict's and Fehling's tests are tests for sugars but the Fehling's test can only detect monosaccharides. So, though the sample gets result with the Benedict's test, the test only yields result with the Fehling's solution if it is a monosaccharide e.g glucose, fructose and galactose.

Solution
The deficiency of manganese in plants results in?
A
death of shoot
B
leaves turning yellow
C
stunted growth
D
poor root development
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
Manganese deficiency can be easy to spot in plants because, much like Magnesium deficiency (agriculture), the leaves start to turn yellow and undergo interveinal chlorosis. The difference between these two is that the younger leaves near the top of the plant show symptoms first because manganese is not mobile while in magnesium deficiency show symptoms in older leaves near the bottom of the plant.
