Explanation:
The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
Answer:
B. Ocean salinity changes with depth at a steady rate throughout the entire water column.
Explanation:
The data in the graph shows that Ocean salinity changes with the depth at a steady rate throughout the entire water column because when the water table rises it brings salts with them at the top so there is high concentration of salts in the upper layers as compared to other layers and going deep in the soil the concentration of salts becomes very low due to upper movement of salts.
Answer:
It prevents salt from flowing in.
Explanation:
so the tubeworm's cell membrane prevents minerals from flowing in and salt is a mineral so it won't allow salt to flow in.
