Question

The function of contractile vacude is to pump out
excess water from the cell. In paramecium, the
actinity of corel soutile vacuole was found to
increase then transferred from one medium to
another. Hence it can be concluded that the
transfer was from :
(a) isotonic to hypertonic
(b) hypotonic to hypertonic solution
(c) hypotonic to isotonic
(d) isotonic to hypertonic​

Answer 1

Answer:

Option b

Explanation:

Osmosis happens from high conc to low low conc ... Thus Hypotonic to hypertonic (on the basis of solute)

Answer 2

Answer:

(a) isotonic to hypertonic

Explanation:

in isotonic - both concentrations are the same

in hypotonic- solvent concentration is more than solute concentration

hence from  isotonic to hypertonic the activity of contractile vacuole increases
