Answer:
Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.
Counting the yearly layers can date them. The oxygen in the water molecules also holds a key to past climate. Scientists are able to use the oxygen atoms in the glacial ice as a proxy for air temperature above the glacier.
Answer:the elongated cylindrical shaft of a long bone is called its. diaphysis. the expanded end of a long bone is called the. epiphysis.
Explanation:
Fungi are responsible for breaking down organic matter and releasing carbon, oxygen, nitrogen, and phosphorus into the soil and the atmosphere
Eukaryotic cells contain
membrane-bound organelles such as nucleus while it is absent in prokaryotic cells.
The membrane-bound organelles present in eukaryotic cells is an organized and
specialized structure which include the nucleus, ribosomes, endoplasmic
reticulum, Golgi apparatus, vacuoles, lysosomes, mitochondria, and, in plants,
chloroplasts. All of these organelles perform different functions within the eukaryotic cells.
