Spinal Cord
A rat is a vertebrate, meaning it has a backbone and an internal skeleton.An animal which is not classed as a vertebrate is known as an invertebrate, rather than a "non-vertebrate".
How many are in yours?
Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.
the fact that one is an invertebrate and one a vertebrate is completely irrelevant to which eats which it is entirely down to the food chain but it is much more common for a vertebrate to eat an invertebrate than the other way around.
Coating materials are often chosen for their resistance to corrosion and wear, which helps to protect the underlying iron material. Coatings can be designed with specific properties to provide longer-lasting protection compared to iron alone, which is more vulnerable to rust and degradation. Additionally, coatings can be reapplied or repaired more easily than replacing iron components, extending their lifespan.
There are many more invertebrate than vertebrate animals.
because it's larger and more effective skeletal system

more than yours.
Your name.
fish The vertebrates have a nebulous starting point. There are some chordates that have more of a notochord than a true vertebrate column. Some taxicologists are more comfortable saying that a Coelacanth has a notochord rather than a vertebrate column when clearly the vertebrate are present in this animal. So its is a matter of your own definition. One could say 'at a stretch' that the hagfish and lamprey are the most ancient vertebrates.
Typically one skull per vertebrate, although, possible deformatites may make it possible for a vertebrate to have more than the norm.
No They have the same # of bones in the neck(7)

That would be your name.
Well its sort of confusing, see since the invertebrate group has more groups than the vertebrate than that means invertebrate would have more organisms.
Osteichthyes, the bony fish class, has over 30,000 species.
