Retrotransposons are class of transposons that contain long terminal repeats and code for an enzyme that synthesize DNA using an RNA template. It is found in all eukaryotes but absent in prokaryotes. About 42% of human genome is made up of retrotransposons. They are particularly abundant in plants, in maize 49-70% genome is made up of retrotransposons.

Answer:
Explanation:
Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.
