Answer: To identify the causative microbe and the effective antimicrobial agent for it
Explanation:
As the name implies, Culture test in microbiology helps to DISCOVER/IDENTIFY the KIND of micro organisms involved in an infection; while Sensitivity tests TELLS the how best to COUNTER the resulting disease effects
Answer: A- Disruptive selection
Explanation: Disruptive selection increases genetic variation as the population begins to be more different when selection existing in nature chooses multiple phenotypes reaching the highest degree which each have particular benefits. However, they tend to make single-celled life form that has interposed characteristics to produce smaller offspring while allowing the organisms that have the highest degree of characteristics to produce more offspring.
Answer:
the answer is A
Explanation:
Taste stimuli produce depolarizing and hyperpolarizing potentials in individual taste cells.
The vacuole is the cell part that hold extra raw material
Answer:
D. The frequency of the Ellis-van Creveld allele is 0.0447 in the isolated population and 0.0026 in the general population, which suggests that genetic drift has occurred in the isolated population.
Explanation:
If we assume that one gene is involved in Ellis-van Creveld syndrome and we name that gene with A, then the genotype of the syndrome would be aa.
In population 1, the frequency of the syndrome is 1/150000=0.0000066(it is the frequency of the aa gentotype)
In population 2, the frequency of the syndrome is 1/500=0.002
According to Hardy-Weinberg equilibrium
p2+2pq+q2=1 (p2 is the frequency of the dominant homozygous, 2pq is the frequency of heterozygous and q2 is the frequency of the recessive homozygous).
q or the frequency of the Ellis-van Creveld allele in Population 1 is
=0.0026
q or the frequency of the Ellis-van Creveld allele in Population 2 is
= 0.0447
