Bone is a rigid, hard, porous solid organic material
Spongy bone can appear yellow because it has some fat in it, and it is possible to see small holes in spongy bone. Also, spongy bone is not long (like the wrist). Compact bone is usually long (like a femur) and white.

What is referred to as 'brittle bones' is called osteoporosis. The change in the structure of bone that causes them to become brittle is a loss of bone density from a depletion of calcium. Think of Swiss cheese: it has holes in it. That is what osteoporosis looks like inside the bone. Instead of it being dense and filled with calcium, it has lots of holes in it, and so becomes weaker and more likely to break, or fracture.
The spongy bone which is the soft inner layer that has little holes and looks like a spongy hence the term spongy bone then the outer layer that everyone sees is the compact bone but the spongy bone is the most important because it cushions the bones when it gets squished and then it wont break
Mottled bone in humans refers to a condition where the bones have a patchy or blotchy appearance when viewed on imaging studies like X-rays. This can be an indication of various underlying conditions such as osteoporosis, osteomalacia, or other metabolic bone diseases. It is important to consult a healthcare professional for proper evaluation and management.

It depends on the bone disease. Some don't impact your life a lot, like osteoporosis, and some kinds of bone cancer you actually can recover from.
Yes many of your bones have holes to allow blood vessel & nerve intervention as well as the interior of many of your bones are very spongy and therefore have holes that do not actually penetrate the surface of the bone, and are like little air pockets (only without the air) Many of the holes that allow veins and such to transverse them are termed "foramen" For instance your spinal cord enters your skull through a large hole at the base of the occipital bone. This hole is called the mental foramen. Plenty of tiny holes are found all over your bones and then there are obvious ones like the eye sockets (which allow the optic nerve(s) to pass to the brain) These holes make up the orbitals.
As the names suggest, compact bone is solid-looking, and forms the outer layers of all bone (and the shafts in long bones). Spongy bone looks like sponge, with small holes, and is found on the inside of bones and the expanded heads of long bones. As the names suggest, spongy bone is softer than the solid, compact bone. With the naked eye, you can see that the compact bone is smooth and located around the outside of a cross-section of bone. Spongy bone, on the other hand, is located on the inside and is very porous, like a sponge.
From the Earth, a full moon looks yellow like cheese and the craters look like the holes in Swiss Cheese.

Ther are many thinks that could be seen a specks on a bone. If what you are seeing looks like holes they are foramina, small passages for blood vessels to pass through.
