<u>EXPLANATION: </u>
There are two poles: North and South Pole in Earth's magnetic field. When lava erupts at mid-ocean ridge, it cools and becomes a hard rock. During this process of cooling, the rock becomes magnetised.
Scientists have discovered that the magnetic field of Earth has been reversed in direction hundreds of times, which means that the polarity of North pole and South pole reverses.
Due to this reversal, a pattern of magnetic stripes is created in symmetry on both sides of the mid-ocean ridges.
B.Prokaryotic cells do not have a true nucleus or membrane-bound organelles.
Answer:
Iv and
Ii
Explanation:
I think they are the main function of human skeleton system.
