cutaneous or spongy bone
Our bones would be very weak and we would break them easily

Aquatic plants need light too and water hyacinths are aquatic plants. They have air spaces inside them which help them to float freely in the water.
Many bones have spaces for blood vessels to run in their main structure as well as a cavity inside them called a marrow cavity. Part of the formation of the marrow cavity is made of spongy bone which is very light weight.This makes them more light weight but still strong.
All bones are light, marrow bones are soft and compact bones are hard.
Bones are light because they are hollow in the middle.
Chicken bones are light, thin and filled with sponge like material and hollow spaces. Human/adult bones are heavy,thicker and full of marrow with no hollow spaces.

Their strength to weight ratio comes from their being a thick tube (cortical bone) with a "scaffold" of cross-connecting spines ( medullary bone) extending throughout the length of the bone. These scaffolds act a little like Rebar metal rods reinforcing concrete.
they have hollow bones because they need to be light
because it is to dark
yes it does..
Aquatic plants need light too and water hyacinths are aquatic plants. They have air spaces inside them which help them to float freely in the water.
Bones are light because they are hollow inside and filled primarily with marrow, a spongy substance which produces new red blood cells in large bones.
