Question
DI 3 0.5 Bone tissue (or osseous tissue) is composed of extracellular collage (a large protein), mineral (calcium salts and other minerals) and bone cells (i.e. osteocytes). Osteogenesis Imperfecta (OI, aka brittle bone disease) is a congenital bone disorder in which a mutation in the DNA results in a change in one monomer of collagen. Improper formation of collagen fibers leads to an irregular arrangement of osseous tissue. This results in brittle, easily broken bones. For Ol, which of the following would be at the same level of organization as collagen? Liver Red blood cell Glycogen Sodium ions DI 4 0.5 Bone tissue (or osseous tissue) is composed of extracellular collage (a large protein), mineral (calcium salts and other minerals) and bone cells (i.e. osteocytes).

Exocytosis Facilitated diffusion Osmosis Active transportExplanation / Answer
3. Red blood cells
In their own systems, they are the the most abundant type of structural and functional unit, and carry out the basic function of the system.
4. Exocytosis
The other listed methods are applicable for small molecules and ions which can easily travel across the membrane.
