Question

drag each item above to its appropriate location in the image. note that every item may not have a match, while some items may have more than one match.
feathers: fluffy down, radial barbs, interlocking; entire structure for waterproofing (marked structural)
males make \milk\ to feed young
sharp, hooked beak for catching fish, krill, and squid
muscles that store oxygen, allowing for prolonged dives of a few minutes or more
layer of blubber for some insulation
huddle in groups to survive cold and high wind

Explanation:

• Behavioral: These are actions or behaviors of the penguin.
• "Males make 'milk' to feed young" is a behavioral adaptation (action of males).
• "Huddle in groups to survive cold and high wind" is a behavioral adaptation (group - huddling behavior).
• Structural: These are physical structures of the penguin.
• "Sharp, hooked beak for catching fish, krill, and squid" is a structural adaptation (beak structure).
• "Layer of blubber for some insulation" is a structural adaptation (blubber layer is a physical structure).
• "Feathers: fluffy down, radial barbs, aftershafts; outer layer for waterproofing" is a structural adaptation (feather structure).
• "Muscles that store oxygen, allowing for prolonged dives of a few minutes or more" is a structural adaptation (muscle structure related to oxygen storage).
• Biochemical: There are no items in the given list that clearly represent biochemical adaptations (related to chemical processes within the body like enzyme production, hormone regulation specific to biochemical pathways; the given items are either structural or behavioral).

Answer:

• Behavioral:
• Males make "milk" to feed young
• Huddle in groups to survive cold and high wind
• Structural:
• Sharp, hooked beak for catching fish, krill, and squid
• Layer of blubber for some insulation
• Feathers: fluffy down, radial barbs, aftershafts; outer layer for waterproofing
• Muscles that store oxygen, allowing for prolonged dives of a few minutes or more
• Biochemical: None (no items match)
