These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure.You can compress it, or squeeze it into a smaller volume. When you push on the plunger you can feel the air pushing back. When you stop pushing, the air inside the syringe will return to its original size.

Which stage of mitosis is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids?
Answer: Anaphase.
Explanation:
The stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
Mitosis is a type of cell division by which a parental cell divides in order to produce two genetically identical daughter cells.Mitosis has four phases prophase, metaphase, anaphase, and telophase.During prophase, chromatin condenses into chromosomes, the nuclear envelope disintegrates and spindle microtubules grow and extend from each pole of the cell.During metaphase, homologous chromosomes line up at the equator plate of the cell, the mitotic spindle is fully developed and it attaches to the kinetochores that appear at the centromeres.During anaphase, chromosomes are separated by the elongation of the mitotic spindle and pulled to opposite poles of the cell.In conclusion, the stage of mitosis that is characterized by microtubules pulling replicating chromosomes apart and separating them into sister chromatids is ANAPHASE.
