I believe the stage of interphase in which cells copy their DNA is the S phase. :)
Answer:
wall
Explanation:
It is composed of peptidoglycan. The wall gives the cell its shape and surrounds the cytoplasmic membrane, protecting it from the environment.
Well I not a computer Genius but no well yes
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.
