Draw a beaker that is filled with water. Label the water with an osmolarity of 0.61M. In the water, draw a single Elodea cell (note: Elodea is an aquatic plant) with a cellular osmolarity of 0.42M. Name this drawing with the tonicity term that best describes the solution of the water in the beaker compared to the osmolarity of the Elodea cell. Then describe what will happen to the tonicity of the cell over time. Make sure to explain the direction that water will flow, small molecules will diffuse, and explain what will happen to this cell over time. Make sure you use all of the applicable tonicity terms in your description.

please explain

Some animals are osmoconformers, meaning that they maintain the tonicity/osmolarity of their body fluids equal to that of the external environment. Hydroids, a type of cnidarian, are osmoconformers. But they don't move and thus are adapted to the environment they live in. A) What would happen if you take a marine hydroid and transfer it into a freshwater aquarium? B) What would happen if you take a freshwater hydroid and transfer it into a saltwater aquarium? C) Sharks are extraordinary osmoconformers. Bull sharks store urea in their tissues and use it to match the tonicity of their tissues to that of the surrounding environment. Some sharks can move from saltwater to freshwater, hypothesize what changes will sharks do in order to adjust when moving from saltwater to freshwater and vice versa. Explain your answer in terms of tonicity and specify the direction of water movement and urea concentration.

An animal like salmon that can survive large fluctuations in external osmolarity is called (?????).
