during dna replication the chromosomes contract and the identical halves are called
Answer:
Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.

An ecosystem that can experience a disturbance without being fundamentally damaged is said to have: Inertia.
An ecosystem can be defined as a biological community or space that comprises all living organisms (biotic factors) and the physical environment (abiotic factors) with which they interact.
Basically, an ecosystem is responsible for the provision of the following essential services that are very vital and important for the sustenance of life in all living organisms;
Plant pollination.Water purification.Nutrient cycling.Additionally, an ecosystem is said to have an inertia if it experiences a disturbance or factor of changes without it being damaged significantly or fundamentally.
For example, the development of shrub forests during the Medieval Warm Period is an inertia of the ecosystem.

stem cells in developing bone that give rise to osteoblasts are called:
Stem cells in developing bone that give rise to osteoblasts are called Osteoprogenitor cells.
What are Osteoprogenitor cells?Osteoprogenitor cells are stem cells found in the developing bone that have the ability to differentiate into osteoblasts, which are the cells responsible for the formation and mineralization of bone tissue.
These cells are crucial for the development and growth of the skeleton and the maintenance of healthy bones throughout life. They also play a role in bone repair and regeneration following injury or disease. By giving rise to osteoblasts, osteoprogenitor cells help to ensure the proper development and maintenance of the skeletal system.
