Question

which of the following allows fish to survive high pressure? fish have gills and not lungs liquid water compresses less under pressure than gas fish bodies are mostly composed of water fish have air pockets in their bodies

Explanation:

• Analyze each option:
• "Fish have gills and not lungs" relates to respiration, not pressure survival.
• "Liquid water compresses less under pressure than gas" is about water's properties, not fish's adaptation.
• "Fish bodies are mostly composed of water": Since water is incompressible, having a body mostly of water helps fish withstand high pressure as their internal pressure can balance external pressure.
• "Fish have air pockets in their bodies": Air pockets would compress under high pressure, harming the fish, so this is incorrect.

Answer:

The correct options are:

• Fish bodies are mostly composed of water
