The process of water loss and intake indicated by the arrow labelled I and II are respectively
exhalation and osmosis
urination and diffusion
osmosis and diffusion
evaporation and osmosis
Correct answer is D
- Most frog species show little resistance to evaporative water loss (EWL) through their skin.
- The movement of water across membranes from areas of high concentration (lots of water) to areas of low concentration (less water) is called osmosis. The reason frogs do not have to actively drink water and instead can sit in a bowl of water and absorb water passively is due, in large part, to osmosis.
- That is, frogs do not drink like we do; they absorb water directly through their skin in an area known as the 'drinking patch' located on their belly and the underside of their thighs.
