Answer: <u>Sinks towards the outer core
</u>
Explanation: The material which is less dense, means it is lighter in weight. Such substances tend to move more towards the crust of the Earth, whereas the heavier substances like iron, is more towards the core or centre of the Earth. This is because heavier substances tend to sink deeper. That’s why the light elements are found in the crust section of the Earth.

5000 ml = 5 liters
Answer:
1→4→5→3→2
∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.
