Hello!! Your answer would be C - Medulla oblongata. The medullary respiratory center includes two groups of neurons that extend throughout the length of the medulla oblongata. They are called the ventral respiratory group and the dorsal respiratory group. The ventral respiratory group is responsible for regulating inspiration and expiration. The dorsal respiratory group stimulates the inspiratory muscles, like the diaphragm (near bottom of ribs). It also helps process sensory information related to the respiratory system. Neurons in the brainstem are a part of the pontine respiratory group which limits inspiration and help the rhythm of breathing. I hope I helped give you a better understanding. Have a great evening!!

Answer:
<em>C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.</em>
Why:
<em>When a species </em><em>adapts</em><em> itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.</em>
<em>(Hope this was a good explanation.)</em>
