Scientists often perform experiments to check and recheck their work. They also redo these experiments to ensure correct results.
If it displays the dominant genotype, we can assume that this plant would have a heterozygous (hybrid) genotype, i.e.
With a purebred recessive plant, the geneotypes would be 50% Bb and 50% bb.
With a purebred dominant plant, the genetpyes would be 50% BB and 50% Bb.
With a <span>heterozygous (hybrid) plant, the genotypes would be 25% BB, 50% Bb and 25% bb.</span>
Answer:
The color would be Pink
Explanation:
According to the question, the bacteria is positive for the enzyme urease and it's inoculated for 24 hours.
Urease broth is a differential medium that tests the ability of an organism to produce urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red. Phenol red turns yellow in an acidic environment and fuchsia in an alkaline environment.
If the urea in the broth is degraded and ammonia is produced, an alkaline environment is created, and the media turns pink within 24 hours.
Many enterics can hydrolyze urea; but only a few can degrade urea rapidly. These are called “rapid urease-positive” organisms.
Urea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink.
