Dry air. The lower the density, the more slowly sound travels. Dry air is the least dense of all the materials listed.
wood
Water:)
Sound will not travel through a vacuum as it needs a medium which will allow vibrations.
It travels faster thru air
That completely depends on what "slowly" means to you.Sound propagating through iron is quite slow compared to the speed of lightin vacuum, but is substantially faster than the same sound in air.
yes it does because air is easier to travel through
Sound travels slowly through gas because the particles in a gas are further away then the particles in a solid or a liquid. This makes it take longer for the sound waves to travel through the particles in gases because it takes longer for them to collide with each other; this makes it take longer for the particles to pass on the sound vibration.
Impulses travel more slowly through unmyelinated nerve fiber.
Yes it can cause sound waves can travel through solids,liquids,but slowly in gases and air

An hot air balloon i think.
outercore
it traps air inside to slow it down
Longitudinal (also know as compression) waves travel more slowly through gasses than solids.
No
Probably very slowly, mostly following migrating food sources.

to allow nutrients to come into contact with the intestinal walls
