two basic cell types amoebocytes and choanocytes b acellular layer of mesohyl c a collar of microvilli on the cells to capture food d ability of some cells to transform into sperm e two mouths 3 Segmentation has evolved independently in a Arthropoda Annelida Chordata b Mollusca Oligochaeta Platyhelminthes c Arthropoda Nematoda Annelida d Annelida Platyhelminthes Chordata e Chordata Mollusca Annelida 4 Where did gnathostome jaws come from a leftover middle ear bones b ribs that moved forward to encircle the mouth c skeletal rods that supported pharyngeal slits d teeth that became internalized and jointed e dorsal hollow nerve cord 5 One result of torsion during development in the Gastropoda snails is a the anal opening comes to lie above the head b the mantle is turned inside out c the shell becomes coiled d the coelom is reduced to a pseudocolom e loss of the radula 6 Lampreys differ from hagfishes in a lacking jaws b having a cranium c having pharyngeal clefts that develop into pharyngeal slits d having a notochord throughout life e having a notochord that is surrounded by a tube of cartilage 7 If you found an arthropod in your basement that had one pair of antennae 20 pairs of legs with one pair of legs per segment it is most likely a a millipede b a spider c a crustacean d a centipede e an apterygote insect Downloaded by Fehintola Disu toladisu12 gmail

suspension feeding using ciliated appendages e water vascular system 9 One difference between Chondrichthyes sharks and Osteichthyes bony fish is a Chondrichthyes have teeth and Osteichthyes don t b Osteichthyes have vertebrae and Chondrichthyes don t c Osteichthyes have a single bony gill cover and Chondrichthyes don t d Chondrichthyes have a swim bladder and Osteichthyes don t e Chondrichthyes are eaten for food by humans and Osteichthyes aren t 10 are the most diverse and abundant group of animals on our planet a sponges b fish c arthropods d flatworms e acoelomates 11 The Phylum Chordata is characterized by a notochord nerve cord pharyngeal cleft and post anal tail The pharyngeal cleft is an example of a n a homologous character for the chordates b evolutionary left over c co evolution d adaptive radiation e convergent evolution 12 The last common ancestor of all animals was probably a a unicellular chytrid b unicellular yeast c multicellular algae d multicellular fungus e flagellated protist 13 What is the probable sequence in which the following clades of animals originated from earliest to most recent 1 tetrapods 2 vertebrates 3 deuterostomes 4 amniotes 5 bilaterians a 5 3 2 4 1 b 5 3 2 1 4 c 5 3 4 2 1 d 3 5 4 2 1 e 3 5 2 1 4 14 The earliest known mineralized structures in vertebrates are associated with which function a reproduction b feeding c locomotion d defence e respiration Downloaded by Fehintola Disu toladisu12 gmail com lOMoARcPSD 10529908 Biology 108 Final Exam 4 increases protection of internal organs their eyespots can carry out respiratory and circulatory functions their body cavity a pseudocoelom carries out these functions 15 Planarians and tapeworms lack dedicated respiratory and circulatory systems because a they lack mesoderm as embryos and therefore lack the adult tissues derived from mesoderm b none of their cells are far removed from the gastrovascular cavity or from the external environment c d e They are anaerobic organisms 16 All of the following are advantages of a body cavity EXCEPT a provides room for heart expansion b results in a radial body symmetry c allows for an increase in complexity of the organ systems d e provides room for lung expansion 17 Many parasitic tapeworms have complex life cycles which means they a must moult in order to complete the life cycle b require two or more hosts to complete the life cycle c have a complex mechanism for evading host immune responses d rely on the definitive host for asexual reproduction e none of the above tapeworms have direct life cycles 18 Which of these statements about the evolutionary tree of animals is incorrect a All animals are heterotrophs b All animals are multicellular c Humans are more closely related to sea stars than to insects d Radial symmetry preceded bilateral symmetry in animal evolution e All animals are deuterostomes 19 Arthropods have a strong protective exoskeleton despite its many benefits there is one major disadvantage a b c d e it blocks the diffusion of oxygen into the body it is made of cellulose which is soluble in water it is jointed in places that make it weak it must be shed during molting in order for the animal to grow it can attack the immune system lampreys 20 Jaws first occurred in which extant group of fishes a b chondrichthyans c ray finned fishes d lungfishes
