- Give at least 10 exoskeletons found in animals, source, its description and state their embryonic origin. (Explain in 1-3 sentences) (Use the table)Sharks are cartilaginous fish. That is, the bulk of their skeleton is composed of cartilage instead of calcified bone. Their jaw however, is calcified, and is often the only preserved part of their body. Examine the shark jaw in the photo, and deduce the overall symmetry of the organism based on the jaw. Bilateral Pentameral Asymmetrical Radialgive 2 examples of animals with exoskeleton and endoskeleton where the hydrostatic skeleton is lost explain scientifically do not just google please
- why do you think hydrostatic skeleton is eventually lost in animals with exoskeleton and endoskeleton? give 2 examples and scientific explanation please do not just copy from google and this site, i need other answersBased on your observations of representative invertebrates (earthworms - hydrostatic skeleton and arthropods - exoskeleton), explain the nature of their skeletons in two to three summary statements.Give the exoskeletal structures of the following vertebrates
- why do some vertebrates possess cartilaginous endoskeleton while others possess bony endoskeleton? give 2 examples with scientific explanation please do not copy from google and here because i need other answers, i will upvoteUsing the table, give at least 10 exoskeletons found in animals, source, its description and state their embryonic origin. (Explain in 1-3 sentences)why do you think hydrostatic skeleton is eventually lost in animals with exoskeleton and endoskeleton? give 2 examples with scientific explanation
- Sharks are cartilaginous fish. That is, the bulk of their skeleton is composed of cartilage instead of calcified bone. Their jaw however, is calcified, and is often the only preserved part of their body. Examine the shark jaw in the photo, and deduce the overall symmetry of the organism based on the jaw.Most land animals with exoskeletons are smaller than the volume of a mouse, and most vertebrates are larger than a mouse (marine invertebrates can be somewhat bigger). What keeps an insect with an exoskeleton from being as big as a horse?Crayfish, unlike earthworms, do not have a hydrostatic skeleton. Instead, crayfish have a rigid exoskeleton. Give 2 advantages to the having the exoskeleton and 2 disadvantages.
