Yes, It is rough and contains many small holes. Igneous rock is formed by cooling of magma/or lava.

There are many trillions upon trillions upon trillions of black holes. Many of them are massive like the one in the center of hour galaxy. However, because they are nearly impossible to see, many go unnoticed. There are also uncountable amounts of microscopic black holes floating all around you. They are so small they are undetectable, but there still there. So to answer your question, yes there are billions of black holes, except there are probably even more than billions out there and we don't even notice them.
Nope Uranium is a very widespread element in nature. All materials of construction, all foods, all waters and soils, etc. contain small amounts of uranium. Uranium concentration in bananas is so small that it is not of practical importance. Even human body contain a small quantity of uranium.
If it's an outlet that's round with many holes it is probably the drain in the sink.
1,744,656 small holes

there are many holes in loaves because of the action of yeast. Very small and regular holes usually indicate that the bread underwent after the action of the yeast, another mixing. If the bread is untouched before being baked, the holes are more irregular and larger.
No, pigs do not have holes in their feet. However, much like many other creatures, pigs do have toes! There is a small separation between toes!
Continous capillaries contain tight junctions and are less "leaky " than fenestrated capillaries. They only allow the movement of water and small ions, whereas fenestrated capillaries contain many fenestrae or pores and allow many molecules with the exception of medium and large proteins to pass
Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).
Sometime after sundown they come out. Generally they are small and many times you can see the holes where they come out.
It is believed that there are black holes in the centers of many galaxies. I believe a super-massive black hole
