Biology, 7e (Campbell) Chapter 40: Basic Principles of Animal Form and Function Chapter Questions 1) How do animal structures well suited to specific functions come about? A) Natural selection favors the most functional structures for a particular environment. B) Mutations arise to provide required structures for survival in a particular environment. C) An animal that needs a new function will develop a new structure to provide it. D) Animals invent structural designs that enhance their functions. E) Animals continually improve their structures in order to improve their functions. 2) Which represent adaptations to the same environmental challenge? A) gastrovascular activity, two-layered body, and torpedo shape B) large volume, long tubular body, wings C) external respiratory surface, small size, two-layered body D) complex internal structures, small size, large surface area E) branched internal surfaces, small size, moist outer covering 3) Why do sharks, penguins, and aquatic mammals have the same fusiform body shape? A) Natural selection shapes similar adaptations when diverse organisms face the same environmental challenge. B) Respiration through gills is enhanced by having a fusiform shape. C) The laws of hydrodynamics constrain the shapes that are possible for aquatic animals that swim very fast. D) A and C only E) A, B, and C 4) Which of the following ideas is not consistent with our understanding of animal structure? A) The environment imposes similar problems on all animals. B) The evolution of structure in an animal is influenced by its environment. C) All but the simplest animals demonstrate the same hierarchical levels of organization. D) Different animals contain fundamentally different categories of tissues. E) Short-term adjustments to environmental changes are mediated by physiological organ systems. 5) Regardless of their size, the one thing that is common to all animals is A) an external body surface that is dry. B) a basic body plan that resembles a two-layered sac. C) the use of homeostatic mechanisms to control their internal environment. D) the use of positive and negative feedback cycles to regulate body water content. E) having cells surrounded by an aqueous medium. 6) Which of the following is a problem faced by animals as they increase in size? A) decreasing surface-to-volume ratio B) reproducing in aqueous environments C) the tendency for larger bodies to be more variable in metabolic rate D) A and B only E) A, B, and C 7) An increase in which of the following parameters is most important in the evolution of specialized exchange surfaces such as the linings of the lungs or intestines? A) surface area B) body thickness C) number of cell layers D) metabolic rate of component cells E) volume of component cells 8) What is the common functional significance of the extended number of cells making up such seemingly different human structures as the lining of the air sacs in the lungs and the wavy lining of the intestine? A) increased oxygen demand from their metabolic activity
