- 8. -lack of equality or equivalence between parts or aspects of something; lack of symmetry
- 9. -a hard covering that supports and protects the bodies of some types of animals.

- 12. zone -The benthic zone is the lowest level of a water body, including the ocean floor, lake bottoms, or riverbeds, and the sediments within it

- 1. -Cartilage is a tough, flexible connective tissue that plays a crucial role in the musculoskeletal system
- 4. Symmetry -symmetry around a central axis, as in a starfish or a tulip flower.
- 5. A vertebrate is an animal with a backbone or spinal column
- 6. whose body temperature is largely determined by their external environment, rather than internal metabolic processes.
- 7. -the process where an animal sheds its outer layer (like skin, feathers, hair, or exoskeleton) and replaces it with a new one, often for growth or to adapt to changing conditions.
- 11. bladder- is a gas-filled organ in bony fish that helps them regulate buoyancy, allowing them to stay at a desired depth in the water without expending energy on swimming.
- 13. (of a reaction or process) accompanied by or requiring the absorption of heat.
- 15. Eggs-Amniotic eggs are a type of egg that are laid by reptiles, birds, and some mammals (monotremes)
- 17. -a hard, internal skeletal system, typically made of bone or cartilage, that provides support, protection, and allows for movement in animals.
