Uvula is soft is a small, and soft conical projection of soft palate; it hangs inside throat. Nasal passage ends behind uvula.
Umbilical cord is a fetal structure which helps the mammalian baby to attach to placenta. Blood vessels remain embedded in gelatinous mass of the long cord. At pacenta, oxygen and carbon dioxode are exchanged between mother's blood and baby's blood. However, their blood will not ever come in direct contact.
There are two arteries and one vein in umbilical cord. The arteries carry deoxygenated blood from fetus to placenta while oxygenated blood come back to fetal heart by the vein.
There are no nerves in the cord: allowing that in the ‘after-birth’ the cord can be safely clamped and then removed by cutting.

Biology

Where is the umbilical cord located? Where is the uvula?

A multiple is a number that may be divided by another a certain number of times without a remainder.

For example, 15 and 30 are multiples of 5 and 15

Distillation works by separating the different boiling temperatures of liquids. To separate two or more liquids by distillation, you first heat them in a flask. The more volatile liquid (the liquid with the lower boiling point) will typically evaporate first and the vapour will pass into a condensing column (Liebig condenser) , where it can revert into a liquid (condense) on the cool glass where it trickles into a collection flask. Heating further will cause the less volatile liquids to evaporate and distill at higher temperatures. The two main kinds of distillation are simple distillation and fractional distillation, and both are used widely.
