Chapter 33.4, Problem 3CC
MAKE CONNECTIONS Ø Historically, annelids and arthropods were viewed as cosely related because both have body segmentation. Yet DNA sequence data indicate that annelids belong to one dade (Lophotrochozoa) and arthrppods another (Ecdysozoa). Could traditional and molecular hypotheses be tested by studying the Hox genes that control body segmentation (see Concept 21.6)? Explain.

- Discuss the idea that every evolutionary adaptation has both advantages and disadvantages, using each of the following as an example: (a) cephalization,(b) the arthropod exoskeleton, and (c) segmentation with specialization.arrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardpart i Animal phylogenies based on molecular and morphological characters can be different in regards to the placement of the phylum Platyhelminthes. What is the best explanation for this?choose 1 a. The Platyhelminthes clade separated from other clades before coeloms evolved and consequently Platyhelminthes have never had a coelom. b. Some Platyhelminthes have a coelom, but others do not and it is difficult to conclude anything about its evolution within the clade. c. Platyhelminthes originated from ancestors with a coelom and have retained it to the present time. d. Modern Platyhelminthes do not have a coelom but did originate from an ancestor that had one. e. Platyhelminthes evolved from an ancestor without a coelom but developed one during the course of their evolution. part ii If current molecular phylogenies of land plants are correct and to be believed they suggest that.

- Lab 10: Kingdom Animalia Introduction Animals all share some characteristics: 1) Multicellular 2) Heterotrophic 3) Their cells have no cell wall 4) At some time in their life they are motile. There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…arrow_forwardPlease solvearrow_forward. WHAT IF?

- Make a phylogenetic tree about: Animalia● Vertebrates● Invertebrates● Porifera● Coelenterata (Cnidaria)● Platyhelminthes● Nematoda● Annelida● Arthropoda● Mollusca● Echinodermata● Hemichordata● Chordata (Label all the synapomorphies and include descriptions and side notes)arrow_forward15. On the tree below, mark the place or places that three tissue layers have evolved in animals. Tissue Lineage Layers Porifera N/A Cnidaria 2. Platyhelminthes 3. Rotifera 3. Annelida 3. Mollusca Nematoda 3 Arthropoda Echinodermata 3. Chordata Is the possession of three tissue layers homologous or convergent among animals?arrow_forwardDifferentiate analogous structures from homologous types. Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a. For each cell, write either AS for analogous structures, or HS for homologous types. Note (not all structures encountered need to be here).arrow_forward

In paleontology, what does transitional form mean?arrow_forwardMAKE CONNECTIONS Many new animal body plansemerged during and after the Cambrian explosion. Incontrast, cnidarians today retain the same diploblastic,radial body plan found in cnidarians 560 million yearsago. Are cnidarians therefore less successful or less “highlyevolved” than other animal groups? Explain.(See Concepts 25.3 and 25.6.)arrow_forward14. Nematode Life Cycle Matching: Match each of the descriptions below with the correct nematode worm species (A-D). Note that some descriptions may not apply to any of the 4 species (in which case just write “none") and some descriptions may apply to multiple worms species (in which case write the letters of all applicable species). (A) Dirofilaria (heartworms) (B) Dracunculus (Guinea worm) (C) Ascaris (D) Hookworms 1. Life cycle includes only a single host 2. The infective stage is a free-living larva that can enter the skin directly 3. On target to become the first parasite-caused human disease to be eradicated 4. Has an arthropod intermediate host 5. Traditional treatment involves winding the female worm around a matchstick 6. Infections can be prevented by not defecating on soill improving sanitation of soil 7. Female lays eggs around the anus of the host 8. Produce microfilaria that circulate in the blood 9. Has multiple larval stages and a snail intermediate host 10. Migrate…arrow_forward
