Answer:
Among the four provided options,
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.
Answer:
Option (A)
Explanation:
The lithosphere represents the rigid outer shell of the Earth, exhibiting brittleness that leads to the fracture of rocks upon deformation. It comprises numerous tectonic plates categorized into two types: the oceanic and continental crusts.
These plates float atop the less dense asthenosphere due to convection currents generated within the mantle. The heat from the Earth's interior causes this current. The movement of plates across the asthenosphere is known as the theory of plate tectonics. Therefore, the correct selection is option (A).
