Answer:
proteins are only able to function properly in their specific shape, they will typically stay in that configuration unless something forces them to change. When proteins change their shape, this is called denaturation. Some external forces that affect protein shape are pH and temperature
If they live in a river, they would most likely need fins (to swim) and gills (to breathe under water)
Hope this helps!

<span>The appropriate answer is c. sonar. Oceanographers use sonar to determine the ocean depth. A sonar signal is sent from the ship. Oceanographers record the time taken for the signal to leave the ship and for it to return. Knowing the speed of sound in water, they are able to calculate the depth of the water. This method is also used to generate bathymetric images of the ocean floor. </span>
