Strawberry aldehyde (C12H1403) is a chemical that helps give strawberries their
smell. Many people enjoy this smell, so strawberry aldehyde is often added to
perfumes and soaps. Factories can make this fragrant chemical by combining
acetophenone (C3H80) with ethyl chloroacetate (C4H2C1O2). This combination forms
strawberry aldehyde and hydrochloric acid (HCI). Making fragrant chemicals like
strawberry aldehyde in a factory is often less expensive than extracting the same
chemicals from plants.

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution
