By which of the following mechanisms do the water molecules most likely move into the large intestine?
а
by passive transport from an area of low osmolarity to an area of high osmolarity
b
)
by passive transport from an area of high osmolarity to an area of low osmolarity
c
by active transport from an area of low osmolarity to an area of high osmolarity
d
by active transport from an area of high osmolarity to an area of low osmolarity

Mechanisms do the water molecules most likely move into the large intestine by passive transport from an area of high osmolarity to an area of low osmolarity.

Option B

Explanation:

Osmotic concentration is otherwise called as osmolarity. Normally osmosis happens from an area of higher concentration to lower concentration. During the process of digestion the required nutrients are absorbed by the body.

Then the water is absorbed in the large intestine by passive transport where no energy is required. Hence water molecules move into the large intestine by active transport from an area of high osmotic concentration to an area of lower osmotic concentration.  

the form of energy changes and the total energy increases0l

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
