Answer:
(B) HEK cells exposed to the most hypotonic conditions will display the greatest degree of AQP5 membrane localization, allowing water to flow into the cells.
Explanation:
The function of AQP5 (an aquaporin) is to allow the water to move into or out of the cell down the concentration gradient. When placed in hypotonic solutions, the internal environment of HEK cells will be hypertonic. Water always moves from hypotonic (higher water concentration) to hypertonic (lower water concentration) solution.
Hence, the HEK cells exposed to the hypotonic conditions will localize AQP5 in their membranes to allow the water to move from out hypotonic conditions to the inner hypertonic environment.
Explanation:
Evolution involves changing the hereditary characteristics of a population through generations. These traits are the expression of genes that are passed on to offspring during reproduction.
Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.
