Answer:
Amoxicillin and Tetracycline
Explanation:
Kirby-Bauer test is used to determine the susceptibility of a bacteria to an antibiotic. The target bacteria is grown on an agar plate. Antibiotic wafers are places on these plates. After some time, the plate is checked. Zone of inhibition (ZOI) is the area around the wafer where no bacteria survived. A reference table is checked for determining the susceptibility of the bacteria to a particular antibiotic. If the value of ZOI is smaller than the value required for susceptibility (S), it means that the bacteria is resistant to that antibiotic.
From the given data, ZOI for Amoxicillin is 25 and S value is ≥29 so the organism in question is resistant to Amoxicillin and Amoxicillin is not an appropriate choice for treatment. Similarly, ZOI for Tetracycline is 18 and S value is ≥19 hence it is not the appropriate choice for treatment.
Maybe D could be the answer
Answer:
50% will be normal and 50% will be carriers
Explanation:
Color blindness is a reduced ability to distinguish between certain colours.
The condition is often inherited. Other causes include certain eye diseases and medication. More men than women are affected.
If such a carrier woman with normal vision (heterozygous for colour blindness) marries a normal man (XY), the following progeny may be expected in the generation: among the daughters, 50% is normal and 50% are carriers for the diseases; among sons, 50% are colour blind and 50% are with normal vision.
