PLEASE HURRY IT IS TIMED. A student is investigating the role of cellular transport in maintaining homeostasis. The student covers one end of a tube containing a 10% sugar solution with a semipermeable membrane. The student places the tube into a beaker that contains a 5% sugar solution. The student observes water from the beaker entering the tube. Which best describes the type of cellular transport that the student is investigating?
A
The student is investigating the active transport of diffusion.

B
The student is investigating the active transport of osmosis.

C
The student is investigating the passive transport of diffusion.

D
The student is investigating the passive transport of osmosis.

The answer that best described the type of cellular transport that the student is investigating would be passive transport of osmosis: The correct option would be D.

To recall: osmosis is simply the movement of water molecules from the region of high water potential to the region of low water potential through a semi-permeable membrane.

From this definition:

The student observed the movement of water molecules from the beaker (high water potential) into the test tube (low water potential).  Hence, active transport and diffusion are ruled out with osmosis being the only correct option.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
