Answer:
The correct answer is - option e.)
Explanation:
The experiment that was performed by Meselson and Stahl was created to prove that DNA replication is a semiconservative process.
When Bacteria grow on 15N media they incorporate the isotype of nitrogen and after few generations, the culture moved to 14N media where it incorporates as they replicate in semi-conservative mode and one DNA strand comes from the Parent DNA.
The right option for question one is Option (e) Run as one band, at a position expected for DNA containing a 14N:15N ratio equal to 1.
Genes are found on DNA, which make(s) up the chromosomes, found in nucleus.

Explanation:all activities of life including physical and chemical require energy to proceed
The analysis of total microbial genomes in an environment is called metagenomics and the total microbial genomes in an environment (or the total microbial community itself) is called a microbiome.
<h3><u>
Explanation:</u></h3>
The study that is associated with the genetic materials that are obtained directly form the sample in an environment refers to the term Meta genomics or ecogenomics or community genomics. It can be considered as the process through which the meta genome is produced.
The genetic material of the microbes such as fungi, bacteria, viruses and protozoa refers to microbiome. These microbes lives inside the body of humans. The weight may range upto 5 pounds for these microbiomes. Micorbiomes are the total number of micro genomes that are present in the environment.
