Not much is currently known about dark matter, but it obviously doesn't react in the same way as normal matter does.
beams of high energy particles that travel almost at the speed of light. they are formed trough accretion.accretion is dust and gaseous matter that is falling in to the black hole. Howe it works i don`t know but it can be explained trough general relativity.check wikipedia for a more detailed answer
seismic waves travel slowly trough
the endoplasmic reticulum its the highway of the cell
Since 1518-19 when Hernan Cortes and his conquistadors had to pass trough it to reach Tenochtitlan (present-day Mexico City).
I believe trough is high tide but I'm not 100% sure A trough is the low part of a wave, the opposite of crest.
Sound waves travel through the three states of matter (gas, liquid and solid) by vibrations.
It depends. Is it a mechanical wave or a electromagnetic wave? Mechanical waves (for example sound waves) travel trough every state of matter and they can't exist without matter. They don't travel through vacuum. Electromagnetic waves travel trough space and get interrupted only by other electromagnetic waves.

no .becoz sperms travel trough urethra not through ureter where stones are present
Both electromagnetic waves and gravity waves can travel through empty space. Gravity waves travel through matter as well; some electromagnetic waves may travel through some types of matter.
All matter. However, sound waves cannot pass through vacuums, such as space.
It's not so much whether they are primary or secondary; the waves that can't travel through liquids, or gases for that matter, are transverse waves.
Egypt.
yes
A perfect vacuum
No, because there is no substance to propagate.
