Question

multiple-choice question how are mamals able to withstand the pressure of the ocean? they are able to hold their breath which prevent compression their lungs are compressible

Explanation:

For marine mammals (note: "mamals" is a typo, should be "mammals") withstanding ocean pressure, the correct reason is related to their physiological adaptations. Marine mammals like whales and seals have compressible lungs (and other adaptations like flexible rib cages) that allow them to handle pressure. The first option is incorrect because holding breath doesn't "prevent compression" in the way described; rather, their lungs can compress as pressure increases, and they have other mechanisms too, but among the two options, "their lungs are compressible" is the more accurate physiological explanation.

Answer:

The correct option is: their lungs are compressible
