<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.

One of the reasons bacteria can be so deadly is because they multiply very quickly. E. coli has a doubling time of around 15 min
Travka [436]

Answer:

The correct answer is - 25600 bacteria.

Explanation:

Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,

100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600

Thus, the correct answer is option- 25600 bacteria.
