In adults, stem cells remain undifferentiated until they are needed to repair or replace other cells. Stem cells can produce cells that are identical to themselves.
Answer:
Water molecules are polar, so they outline hydrogen bonds. This gives water great properties, such as a for the most part high bubbling or boiling point, tall specific warm, cohesion, grasp, and thickness. Hydrogen has an electronegativity of 2.0, though oxygen has an electronegativity of 3.5. The refinement in electronegativities is 1.5, which infers that water can be a polar covalent molecule. In water, an electron from each of the hydrogen particles is drawn towards the oxygen particle. Protons, as unequivocally charged hydrogen particles, move outstandingly rapidly in water from one water molecule to the taking after, which is why the conductivity of water is modestly tall.
Answer:
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells
