Answer:
4) molecule, cell, organ system, population, ecosystem, biosphere
Explanation:
Various biomolecules such as carbohydrates, proteins, lipids, etc. together make the cells. Cells are the structural and functional units of life. A group of cells destined to perform specific functions makes tissues and various specific tissues together make an organ.
An organized group of tissues and organs that work cooperatively to perform a specialized set of functions is called an organ system. For example, the digestive system includes organs involved in the breakdown of nutrients.
A group of organisms of the same species that live in a defined geographic area at the same time make a population. Ecosystem refers to an interacting system including a biotic community and its nonliving, physical environment. The biosphere includes all of the parts of Earth where life forms exist and include the atmosphere, the hydrosphere and the lithosphere.
Mitosis would be skin cells, bone cells, and organ cells. Meiosis is sex cells, so sperm and egg cells.
The answer that goes in the blank is Division.
Answer:
Pioneer species is the general name for the first organisms to move into a disturbed environment or to grow after a volcanic eruption covers an area with lava.

Answer:
Osteochondral Progenitor cells
Explanation:
Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.
The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.
Thus, Osteochondral Progenitor cells is correct.
