We have that for the Question "since ph can affect the activity of the <u>antibiotics</u> why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that
- Why the Kirby <u>bauer </u>test require that the agar have a ph of 7.4 is because while <em>agents </em>may be in excessive activity, given a scenario that the <em>pH </em>is to exceed 7.4 the results might inverse.
From the question we are told
since ph can <em>affect </em>the activity of the antibiotics why would the Kirby <u>bauer </u>test require that the agar have a ph of 7.4
Generally
Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared
Therefore
Why the Kirby <u>bauer </u>test require that the agar have a ph of 7.4 is because
while <em>agents </em>may be in excessive activity, given a scenario that the <em>pH </em>is to exceed 7.4 the results might inverse.

Chromosome is to cactus as gene is to a needle.
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.

The correct answer is option B) their DNA sequences.
The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
