Hello! Help me please.​

Sound travels by vibrating the particles in the medium so that they bump into each other. ... In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium.

Answer

Sound waves are traveling vibrations of particles in media such as air, water, or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
