Answer: actively pump water back into their cells to counter its loss due to osmosis.
Explanation:
The salt lake is the hypertonic solution that means it exhibit the high concentration of salt as compared to what is present in the cells of the organisms. Thus the cells of animals or plants in the hypertonic solution shrinks as they will loose water. The water moves from the higher concentration to the lower concentration.
The brine shrimp cells will shrink in the hypertonic solution of the salt water. Thus the shrimp will actively take or pump water inside the cell to counter balance the loss of water caused due to osmosis.
Answer:
vaccination

Vaccination also called immunization is the administration of antigenic material called a vaccine to produce active artificial immunity against a disease.
