No! Its not possible for a solution to test positive for benedict`s and test negative for barfoed `s test as both detect the presence of reducing sugars and the only difference between the two tests is that further confirmation of a mono or disaccharide is done in barfoed ` s test.
Two possible categories: positive and negative
Yes it is possible...
Glucose, fructose, maltose, sucrose, lactose, and starch are carbohydrates that would likely test positive in Molisch, Benedict's, Barfoed's, Seliwanoff's, Bial's, and fermentation tests. These carbohydrates are commonly used in biochemical testing due to their distinct reactivity with the specific reagents in each test.
A positive, O positive, A negative, or O negative; all are possible
this is not possible
There are just three possible cases: Positive integer: positive x positive = positive. Negative integer: negative x negative = positive. Zero: zero x zero = zero.
yes
Radii are always positive. No, it is not possible to draw a circle with negative radius.
Yes, it is possible for velocity to be negative. Negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
No, a negative times a negative would be a positive and a positive times a positive would also be positive, and anything multiplied by zero would still be zero
No. Two rhesus-negative parents cannot have a rhesus-positive child.
It is possible to have inconclusive test results, but not to test both positive and negative at the same time.
