Answer:
the frequency of individuals with Type B blood in the population is 0.1977
Explanation:
Given:
Frequency of A allele is p = 0.24
Frequency of the individuals with blood type O is r = 0.38
Question: What is the frequency of individuals with Type B blood in the population, fB = ?
You need to apply the Hardy-Weinberg Equilibrium:
p²+q²+r²+2pq+2pr+2qr = 1
Here,
p, q and r are the frequencies of the alleles
Calculating the frequency of the allele q:

q = 1-p-r = 1-0.24-0.6164 = 0.1436
Frequency of individuals with type B blood:

Pure and accurately labeled.

Answer:
When the test culture was removed from the incubator and there was gas bubble in it.The gas bubble produced from the test tube is nitrogen. But if the addition of the zinc and other reagent in the culture and there is no response.
It suggest that the nitrates is being used by the bacteria. The bacteria inside can be aerobic and facultative anaerobic.
They can be gram negative microorganism and yes the occurrence states that the test was successful if the test was about facultative anaerobic and aerobic.
