When comparing genomes from different species, scientists are often interested in the genome density, or the number of genes per
Setler79 [48]

The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density than humans. An example is bacteria with gene densities ranging between 100 – 500 genes/Mb.

shutvik [7]

The velocity (speed) of a sound wave (any wave in fact) is related to its frequency and wavelength by the equation . This is easy to remember since it's a distance divided by a time because frequency is the inverse of the period.

Since for sound traveling through the given solid object we have that  and , the speed of sound will be:
