- . Structure and function is a central theme to the study of biology. Each major group of organisms has evolved its own body part “tool kit" – a collection of structures that have evolved in ways that make specific functions possible. From capturing food to digesting it, and from reproducing to breathing, organisms use structures that have evolved into different forms as species have adapted to life in different environments. The structure of wings, for example enable birds and insects to fly. The structures of legs enable horses to gallop and kangaroos to hop. a. Think about your own teeth. What kinds of foods do you think human teeth are suited for? b. List at least three ways the structure of human teeth serves the function of eating these food materials. c. Now, finally apply the theme of structure and function to something you're very familiar with - your hands. List out all the ways you can think of that the structure of your hands serve the function of your hands.arrow_forwardWhich choice best describes a reasonable mechanism for animal structures becoming better suited over evolutionary time to specific functions? Animals that eat the most food become the most abundant. Animals that restrict their food intake will become less abundant. Animals with mutations that give rise to effective structures will become more abundant. Animals with parents that continually improve their offspring's structures will become more abundant. Animals with inventions that curtail reproduction will become more abundant.arrow_forwardList the major of four characteristics common to all organisms.arrow_forward
