Explicación

## Step 1The question is asking about the respiratory system of cetaceans, which include species such as dolphins, whales, and porpoises. These marine mammals have a unique adaptation that allows them to breathe air while underwater.## Step 2Cetaceans do not have nostrils near their nose, as in humans. Instead, they have a blowhole, which is a specialized opening on the top of their head.## Step 3The blowhole is used for breathing. When a cetacean needs to breathe, it surfaces and opens its blowhole to take in air. The air then travels down the respiratory tract and into the lungs.## Step 4The blowhole is not used for smelling or other sensory functions. It is solely for breathing.## Step 5The options "a nose" and "gills" are incorrect. Cetaceans do not have nostrils near their nose, and they are not fish, so they do not have gills.
