How does the structure of abone make it strong yet lightweight?

the component materials and their arrangement

Explanation:

Bone are important for movement in animals.bones is made up of 15% water,30% collagen fibres and 55% mineral salts..bone cells are widely separated. The Collagen makes bones soft and flexible. Mineral salts makes it fragile and strong.

The osteogenic cells builds the bones and the osteoclasts breaks down older bone tissue, in order to keep the body strong.

Spongy bones contains tiny spicules that helps in strength.

It also reduces the weight of the bones .

The cells of Compact bones are arranged in the direction of stress to keep the bone strong.

They are constantly changing throughout life

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
