I think the answer would be c but I’m not sure
Answer:
Magnetic reversals
Explanation:
When the Earth's magnetic field reverses, a new stripe, with the new polarity, begins. Such magnetic patterns led to recognition of the occurrence of sea-floor spreading, and they remain some of the strongest evidence for the theory of plate tectonics.
Have a great day!! Hope this helps!!
Answer:
The membrane is made from polar phospholipids allowing water to move freely in and out of the cell
Explanation:
The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.
The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.
