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:

Explanation:
Cholesterol is a lipid organic molecule which is the modified steroid form. The cholesterol is secreted by the animal cells as it a constituent of the animal cell membrane.
The cholesterol easily dissolves in the blood and is hydrophobic in nature so cholesterol is transported into the blood plasma in the form of lipoprotein complex.
There are four types of lipoproteins formed on the basis of their cholesterol density which are: VLDL, LDL, IDL and HDL.
HDL or high-density lipoprotein transports the cholesterol to the hepatic cells of Liver where the Liver enzymes convert the cholesterol to the bile acid and thus bile juice is excreted with bile.
Thus, True is the correct answer.
Human cells that contain one set ofchromosomes are called gametes, or sex cells; these are eggs and sperm, and are designated 1n, or haploid.Matched pairs of chromosomes in a diploid organism are called homologous (“same knowledge”)chromosomes
