Question

multiple choice
what helps bighorn sheep absorb the impact when ramming into each other?
this question is worth 2 point(s)
flexible cartilage in their horns.
soft fur around their heads.
a honeycomb pattern in their horn bones.
extra muscles in their necks.

Explanation:

Bighorn sheep have a honeycomb - like structure in their horn bones. This structure acts as a shock - absorber. When they ram into each other, the air pockets and the complex geometry of the honeycomb pattern can dissipate the impact force. Flexible cartilage in horns (A) is not the main impact - absorbing feature. Soft fur (B) provides minimal impact absorption compared to the bone structure. Extra neck muscles (D) are more for movement and support rather than direct impact absorption during head - on collisions.

Answer:

C. A honeycomb pattern in their horn bones.
