They are "casting" holes left from the manufacturing process. The source of water would have to be either from the overflow entrance, a crack or pin-hole in the sink basin, or a faulty or improperly installed p.o. ( vertical drain pipe from lav to p-trap).
stomata
The sink sits on the pedestal and there is a hole or slot on the bottom edge that rests against the wall. A large screw or lag screw is put through these holes and into the wall. There should be a 2x6 or wider board in the wall for this purpose in the original construction.
There is a drain at the bottom so the basin can be emptied, and there is an opening (another drain) near the top so that if someone leaves the water running, the water will never reach the top of the basin and overflow.
the holes in the underside of the leaf is called '' stomata''hope that helped
Hawking radiation is a form of energy that is theorized to be emitted by black holes. It is named after physicist Stephen Hawking, who proposed its existence due to quantum effects near a black hole's event horizon.
xylem
They breathe through the stomata and other pigments.Plants have these tiny holes on the underside of the leaves that allows them to absorb co2 and produce O

Young children are easily curious individuals and as such, will explore the world they are in. Pedestal fans, while convenient, are dangerous due to the open holes which children may put their hands in injuring themselves. In addition the rotating portion of the fan is an easy trap for curious fingers. The wires of these fans may also fray posing an electrical danger.
door drain holes are plugged. open door and look at underside for drain holes. open them with a small screwdriver. door may need vacuuming inside to remove crap like pine needles that get inside.
Stomata are little pores (holes) on the underside of leaves through which they "breathe". It is not clear how you would "calculate" them and so what role standard deviation has in any of this.
Leaves have holes in them for two reasons. One is to take CO2 in. The other reason is to let O2 out. These holes are on the underside of the leaves, and are called stoma. When these holes open, O2 is released into the air. That's why it's said that plants produce oxygen, because it is a waste product from photosynthesis and is released through the stoma.
