Question

Which of the following examples illustrates osmosis?
a. .Water leaves the tubules of the kidney in response to the hypertonic fluid surrounding the tubules.
b. .Digestive enzymes are excreted into the small intestine.
c. .White blood cells consume pathogens and cell debris at the site of an infection.
d. .Calcium is pumped inside a muscle cell after the muscle completes its contraction.

Answer 1

An example of osmosis is when the water leaves the tubules of the kidney in response to the hypertonic fluid surrounding the tubules. Osmosis in the kidneys is a filtration. Osmosis will filter the water molecules and solutes in the kidneys from the plasma to the tubule. The other choices given are not an example of osmosis. The correct answer to this question is A.
