Question

Like mammals, dolphins breathe air, but they are born underwater. Which is an innate behavior that a dolphin uses to breathe for the first time? A. an ability to communicate with clicks and whistles B. an impulse to swim to the surface C. special eyes that see underwater D. a blowhole on top of its head

Answer 1

The answer is B.  This is because baby dolphins, when born, can't really comprehend a lot of things yet, so they, and the more adult dolphins there, try to get to the surface of the ocean to take a breath.  :D  I hope I helped!
