Recently, scientists noted that stained chromosomes from rapidly dividing cells, such as human cancer cells, contain numerous da

As you can see from the question above, the stained chromosomes of rapidly dividing cells contain numerous dark and dotted structures; on the other hand, older human cell chromosomes that have stopped dividing have very few, if any, similar structures. to points. From this we can imagine that these dark dotted structures may have some influence on the rate of cell mitosis. Of course some research must be done to prove this, but if we are to generalize what these structures can cause, we can say that they may increase the rate of mitosis in human cells

The mantle Explanation: The convection zone of the sun is its outermost layer where heat transfer by convection happens which is similar to the Earth’s mantle.
