Which type of symmetry does each of the following animals display? Sponge, hydra, bobcat, jelly, snake,...
Which of the following statements comparing symmetry in sessile and swimming animals is most probable? - Radial symmetry occurs most frequently in animals that catch their prey by rapid swimming. - Bilaterally symmetric animals can be streamlined for swimming, but radially symmetric animals cannot. - Bilateral symmetry allowed animals to evolve nerves. - Radial symmetry is more advantageous for active swimming than is bilateral symmetry.
Question 22 (2 points) Which of the following is not a reptile? Turtle Crocodile Salamander Snake Question 23 (2 points) Which statement about the symmetry of Echinoderms is TRUE? Echinoderms are bilaterally symmetrical as adults. Echinoderms exhibit no symmetry as adults or larvae. Echinoderms are closely related to jellyfish and hydra because they are radially symmetrical as adults. Echinoderms belong in the Bilateria because their larvae show bilateral symmetry, even if adults do not.
Give answer in type format 5)Based on DNA, anatomical, embryological, and some fossil evidence, biologists believe that the following were major events in the evolution of animals: coelomate/acoelomate deuterostome/protostome radial/bilateral symmetry/asymmetry Following the main line of animal evolution leading to chordates (the phylum humans are in), place these events in correct time order and indicate which of each pair leads to chordates.

They are diploblastic, which means they have et arranged in two body layers, the outer epidermis layer that arises from an ectoderm in the embryo and the gastrodermis layer lining the gastrovascular cavity that arises from the endodermal layer in the embryo. As in...
12. How is radial symmetry an advantage to sessile or planktonic animals? 13. The embryo becomes layered during gastrulation, and these germ layers form the various tissues and organs of the body. The names of the germ layers describe where they are found in the early embryo: 14. Each germ layer forms specific tissue types. For example, where is the ectoderm, and what does it give rise to? 15. What are three functions of the body cavity? 16. What is...
Which of the following organisms would NOT display bilateral symmetry because of its feeding behavior? A. a bee that collects nectar from flowers B. a fish that follows its prey over a long distance C. a filter feeder that eats food carried by currents D. a crab that searches for debris on a beach
1. Which of the following features is found in the common ancestor of the deuterostomes? Radial symmetry Notochord Pharyngeal slits 2. Which of the deuterostome groups does not display bilateral symmetry at some time during their development? Echinoderms Hemichordates Chordates None of the above 3. Which of the following deuterostome groups include species that live on land? Hemichordates Chordates Echinoderms
11. Which of the following pairs are mismatched in arthropods? A. compound eyes-vision B. olfactory receptors-smell antennae - touch & sense environment tube feet-locomotion 12· The distinction between protostomes and deutensames is based on differences in their A. digestive tracts B. nervous systems C. circulatory systenss E. eye spots 13. Most mollusks have a A. jointed appendages B. suckers used in for feeding. C. radula D. tube feet E. teeth 14. Which of the following pairs are mismatched in mollusks,...
10.a. Describe the differences between the terms in each of the following pairs. (i) Coelomate versus acoelomate body plan (ii) Protostome versus deuterostome development (ii)Radial versus bilateral symmetry (b) Explain how each of these pair of features was important in constructing the phylogenetic tree shown below. Use specific examples from the tree in your discussion. 24-10 20 11.1 11.The two phylogenetic trees shown on the next page represent the relationship of whales to six other mammals. All of the organisms...
1. If you were to build a phylogenetic tree of living animals, which of the following derived characters would appear first? A. deuterostome development B. true tissues C. protostome development D. bilateral symmetry 2. Birds and mammals are endotherms. They maintain body temperature by producing heat through metabolism. Endothermy is energetically expensive for an organism, yet endotherms have become the dominant group of tetrapods. What is a major evolutionary advantage of endothermy? A. Endothermy allows greater independence from water. B....
