What is the ratio of focal length of a spherical mirror to its radius curvature?
The focal point of a convex mirror lies on the same side as the centre of curvature and is at a distance of half the radius of curvature from the optical centre.
What is Marrow replacement process?
This is bone marrow transplant. A compatible donor should be screen and crossmatch before they can perform the transplant.
Yes, it can be. You can bone a fish, which means to remove its bones in preparation for eating it.
Everything in a bone is organic. The word organic refers to something coming from something that is naturally occurring. Since bones are naturally occurring in animals, they are completely organic.
What are the two layers in bone?
The top layer is called periosteum, which is a slippery thin tissue that covers the areas where tendons (the things that connect bone to muscle) and ligaments (the things that connect bone to bone).
Under that, there is a layer of compact bone, which is solid bone and very heavy.
Under the compact bone, there is spongy bone, which has little holes in it and looks somewhat like a sponge. This layer is not soft or squishy, even though you would expect it to be considering it's name. Spongy bone is lightweight, but serves the same purpose as compact bone, except is lighter and enables you to lift it.
In the larger bones, you would find bone marrow in the center of the bone. The red marrow manufactures blood cells, and the yellow marrow stores fat (the color of the marrow depends on it's location).
In smaller bones, instead of marrow, the bone would be filled with more spongy bone.

Why do infants require more sleep than adults?
So the energy they have can be spent more efficiently by allowing their body to grow. Adult bodies are already grown nearly to the maximum, which means they wont need as much time sleeping for their body to develop.
Anne Dambricourt Malasse (Paleontologist).
The small bone is called the 'sphenoid' - a bone about 10 cm wide, shaped like a butterfly, located at eye level just underneath the brain and being the nucleus around which first our skull, then our entire skeleton take shape over the course of our development.
The sphenoid is also the first bone to form within the embryo.
