Classical biotechnology dates back about 100, 000 years ago.
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.

<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.
1) The first stage of mitosis is actually just the condensing of the chromosomes.
2)They start out as double, then gradually get to the same number.
3)Cell actually spend the most time in the G phase of the cell cycle.
