Question 9

Which of the following options does not correctly describe an adaptation or mechanism for efficient gas exchange in bony fish?

The thin lamellae epithelium and capillaries minimize the diffusion distance.

A concurrent flow system ensures a concentration gradient of oxygen is maintained across the entire length of the lamellae.

Multiple gill filaments and lamellae provide a very large surface area for diffusion.

Coordination of the buccal cavity and operculum maintains a continuous flow of oxygenated water over the gills.
