Which student’s answer describes and explains an internal adaptation that allows for a specific function?
Explanation:
As internal adaptation refers to anatomical adaptation so correct option is B - Student 2: Birds have hollow bones, enabling them to fly.
The bones of birds have hole openings inside. Therefore, chicken bones are much less dense than human bones. These hole areas purpose the chicken to have lighter mass, permitting a less difficult raise for flight. Birds additionally have air sacs which can be extensions of their lungs. Hollow bones also are referred to as pneumatized bones, which means they may be full of areas for air. It is the notion that this shape allows for oxygen consumption throughout the flight. Air sacs are connected to the hole regions in a chicken's bones.What is the use of feathers?Birds have feathers that assist them to fly. The lengthy flight feathers at the wings and tail assist birds' stability and steering. In addition, birds have a device of air sacs of their frame that hook up with the lungs. The air sacs permit birds to extract plenty greater oxygen from every breath of air than different animals can.
Thu it is clear that birds have hollow bones, enabling them to fly is an internal adaptation.

Answer:
D. as you move down the structure, there are fewer organisms in each group.
Explanation:
When we move down from kingdom to species, the number of organisms decreases because more closely related organisms are placed down the group. There are fewer kingdoms that have a large number of organisms in it and has less similarities among them and when we move down, the number of organism decreases in number and at the end there are few organisms are present in it which is more closely related to each other.
