2 which fact helps you conclude that an organism has an endoskeleton? a the organism is an invertebrate. b the organism has a hard shell. c the organism is a vertebrate. d the organism excretes chitin.
Answer
Brief Explanations:
- Option A: Invertebrates usually have exoskeletons (like insects) or no hard skeleton, so this can't conclude an endoskeleton.
- Option B: A hard shell is typical of an exoskeleton (e.g., snails, crabs), not an endoskeleton.
- Option C: Vertebrates have an endoskeleton (internal skeleton made of bone or cartilage), so this fact helps conclude an endoskeleton.
- Option D: Chitin is part of exoskeletons (e.g., arthropods), so excreting chitin relates to exoskeletons, not endoskeletons.
Answer:
C. The organism is a vertebrate.
