Question 20

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.
