After swimming in the ocean for several hours, the swimmers noticed that their fingers appeared to be very wrinkled or shriveled up. this is an indication that seawater is relative to the fluid in cells. a) isotonicb) hypotonicc) hypertonicd) none of these

c) hypertonic

Explanation:

Hypertonic solution -

It is the solution , having more concentration of the solute than any other solution , is termed to as a hypertonic solution .

And , similarly ,

The solution with lesser concentration than any other solution , is known as hypotonic solution .

Hypertonic solution have higher osmotic pressure than another solution , or , in simple words , the solution to be hypertonic in nature , will have more number of solute particles outside the membrane than that is present inside it .

The most common example of a hypertonic solution , is the salt water solution ,

Hence , from the question , the water in the swimming pool is salty in nature and hence is a hypertonic solution .

As , the fingers got exposed to this hypertonic solution , and it get shrinked , as the water from the fingers goes to the swimming water , and hence get shrunken and wrinkled .
