Why does sound of an approaching train is heard latter in air than the sound through rails?
O som gerado por uma locomotiva propaga-se tanto pelo ar quanto pelos trilhos. Como os trilhos estão no estado sólido, as ondas sonoras possuem maior velocidade e podem ser percebidas antes das ondas que se propagam pelo ar.

How are drains set out using travellers boning rod and sight rails?
Boning Rods and site rails are traditionally made from timber, but there are reusable plastic ones on the market (called Cross-Bones). They are positioned on construction sites by the site engineer.The site rails are positioned usually at the manhole point and the boning rod is used as a mobile indicator of the amount of excavation required to reach the pipe soffit. The rails are set at a uniform height above the manhole invert (say 3m) and the boning rod is made to the same depth. The pipe layer then uses the rails to eye in the boning rod to guide the machine driver so he doesn't excavate too deep or too shallow along the length of the pipe run.

What are the building blocks of DNA and RNA?
NucleotidesNucleotides are the monomers, building blocks, of nucleic acids (DNA and RNA). Each nucleotide includes three components: a phosphate, a sugar, and a nitrogenous base. The phosphate is bonded to the sugar through phosphodiester bonds and makes up the backbone of the molecule. The nitrogenous bases form the "rungs" of the ladder and are connected through hydrogen bonds. The phosphate is the same in DNA and RNA, but the sugar can be a ribose (for RNA) or a deoxyribose (for DNA). The latter is a ribose without "de-" one oxygen "-oxy-". There are four available nitrogenous bases in a DNA's nucleotides: adenine, thymine, guanine, and cytosine. RNA nucleotides feature the same bases with the exception of uracil, which replaces thymine. See related links and questions below.
