Option C. Facilitated diffusion

is the correct choice.

Explanation:

In a hypertonic solution, water movement occurs through specific channels called 'aquaporins' embedded in the cell's plasma membrane. This transport method is categorized as passive, allowing ions or molecules to move through a transmembrane protein seamlessly. This transport mode is known as passive mediated transport, or more commonly as facilitated diffusion.

Describe how paleomagnetism is<br> Used to calculate the rate of sea floor spreading?
Natalka [282]
About every 50,000 years, the Earth's magnetic poles flip. As basalt emerges from the ocean floor due to seafloor spreading, the iron within it aligns according to the magnetic pole's position. Paleomagnetism is the study of this magnetic orientation in ancient rocks. So, if you examine a section of seafloor and identify three areas that show magnetic pole reversals, you can determine that approximately 150,000 years have elapsed based on the frequency of those reversals.
