You believe a bacterium is attaching to animal cells by binding to the carbohydrate portion of a specific glycoprotein. to test this hypothesis you pre-incubate the bacteria with various molecules and then test for inhibition of attachment to the animal cells. which result supports the hypothesis that the bacteria recognize the carbohydrate component of the animal glycoprotein? see section 5.3 (page 114) . pretreatment with the protein component alone prevents bacteria attachment to the animal cells. pretreatment with the entire glycoprotein prevents bacteria attachment to the animal cells. pretreatment with the entire glycoprotein allows bacteria attachment to the animal cells. pretreatment with the carbohydrate component alone prevents bacteria attachment to the animal cells.

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

2. how does the miller-urey experiment fall short of demonstrating that life can arise from inorganic molecules? explain. a. it doesn't show a leap between a collection of amino acids and a single-celled organism. b. it recreates the conditions that existed at the earth's beginning, but no molecules form as a result. c. it doesn't provide evidence of the formation of amino acids. d. it doesn't show how multicellular organisms developed from unicellular organisms
