since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4

Nutka1998 [239]

We have that for the Question "since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that

Why the Kirby bauer test require that the agar have a ph of 7.4 is because while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

From the question we are told

since ph can affect the activity of the antibiotics why would the Kirby bauer 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 bauer test require that the agar have a ph of 7.4 is because

while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t

Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² + 2pq+ q² = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = $\sqrt{0.35}$ = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.
