- 1 page please: Dogfish sharks (Squalus acanthias) represented “primitive” gnathostomes and cats (Felis catus) represented the “derived” state. Was this appropriate? How does the anatomy of a cat reflect humans’ shared ancestry with sharks?Based on the paper entitled "Back to Basics: Cnidarians Start to Fire" discuss species and classification of species with neural crest.How does the anatomy of a cat (Felis catus) reflect humans shared ancestry with dogfish sharks?

- Pharyngeal slits are which of the following? Question 24 options: a) Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth. b) Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. d) Tissues that produces thyroid type hormones. e) Hollow tubes that develops from ectoderm. Develops into the central nervous system.Animal Kingdom, Part I Background: There are ten major phyla that represent the invertebrate animals. Though they all share animal characteristics, each phylum has unique characteristics that allow for identification and classification of those organisms. Scientists do not always rely solely on their memory to help them classify animals, they often rely on reference materials. In this activity, you will create your own reference for the animal kingdom. Instructions: Review the information found in the lessons on invertebrates including The Animal Kingdom, Body Plans, Phylum Placazoa, Phylum Porifera to review the key characteristics that define the phyla that you study. Create a concept map or illustrated drawing for each phylum (Placazoa and Porifera) that will help you classify invertebrate animals into that group.Compare the overall body structure of the cave fish and the minnow below. cave fish minrow 1. What is the biggest, most obvious difference between the body structure of these two fish? 2. Assume the two fish came from the same original ancestor. Why might the cave fish have evolved withouteyesight? 3. What kind of sensory adaptation would you hypothesize the cave fish has to allow it to navigate in a cave, including catching and eating food?
- List four very different anti-predator adaptations used by different invertebrate deuterostomes and the names of each animal group (common names are fine). Please only do invertebrae NOT vertebrae‘s. Thank youLiving vertebrates can be divided into two majorclades. Select the appropriate pair.(A) the chordates and the tetrapods(B) the urochordates and the cephalochordates(C) the cyclostomes and the gnathostomes(D) the marsupials and the eutheriansIn 1928 Walter Garstang hypothesized that tunicates resemble the ancestral stock of the vertebrates. Explain this hypothesis and evaluate its validity with recent phylogenetic, fossil, and developmental data.
