No, after the alpha decay of polonium lead isotopes were obtained.
Tunnels for protein export in a cell are known as nuclear pores. These are large protein complexes that span the nuclear envelope and facilitate the transport of molecules like proteins and RNA between the nucleus and the cytoplasm. Nuclear pores are crucial for regulating cellular processes and maintaining cell function.
No, there are no tunnels from pyramids to the center of the Earth. Such claims are purely speculative and not supported by any scientific evidence. Pyramids were built for various purposes such as tombs or religious monuments, not for connecting to the Earth's core.
The type of rock fragment that contains holes and tunnels left by escaping gases is called a vesicular rock. These holes and tunnels are known as vesicles, and they form when gas bubbles are trapped in magma during solidification. Examples of vesicular rocks include pumice and scoria.
I don't know for sure, but since you asked for an opinion... I have two theories. 1. The tunnels and holes are there to allow for the absorption of more oxygen from the water around it. 2. The tunnels and holes are there to provide shelter for smaller organisms that form a symbiotic relationship with the sea sponge.
Blown around and compacted are what happens to dirt from mole tunnels. The mammal in question (Talpidae family) compresses some of the dirt to form non-collapsible tunnels underground and ejects the rest out the entryway (for compaction in place or movement by people, rain, wildlife, and wind.
they are vertical tunnels, angle tunnels, and horizontal tunnels. THE END
yes there are tunnels
Some of the best hamster cages with tunnels available in the market include the Habitrail OVO Dwarf Hamster Habitat, the Ferplast Hamster Cage with Tubes, and the Kaytee CritterTrail Z Habitat. These cages provide ample space for hamsters to explore and play, with tunnels that add an extra element of fun and enrichment to their environment.
when they finish making the tunnels
Not tunnels for auto traffic. There are two auto tunnels on the westbank of the Mississippi River.
Depends on what you mean by tunnels. There are the short tunnels that allow you to move from playground to street and vice-versa.
