Among them, carbon is the most abundant element by percentage that makes up the human body. 8.Molecular shape is crucial in biology, morphine and heroin mimic endorphins by binding to endorphin receptors in the brain is a good example. 9.Miller-Urey-type experiments prove that organic compounds may have been synthesized abiotically in the early Earth if the atmosphere were reducing. 10.The pentose is ribose in RNA and deoxyribose in DNA. The only difference between these two sugars is that deoxyribose lacks a -OH group on the second carbon in the ring. 11.Trypanosoma kinetoplastids cause sleeping sickness in humans which is spread by the African tsetse fly, and also cause Chagas' disease transmitted by bloodsucking bugs. 12.Evidences now support the view that bacteria and archaea represent two very distinct branches of prokaryotic life. 13.The concept of enantiomers is important in the pharmaceutical industry because the two enantioers of a drug may not be equally effective. 14.Phylogenetic trees and taxonomic groupings are testable but not falsifiable hypotheses that fit the best available data. 15.Cellular slim mold is a diploid organism and has become a model organism for addressing the evolution of multicellularity. 16.Most proteins become denatured if they are transferred to an organic solvent since the polypeptide chain refolds so that its hydrophobic regions face outward toward the solvent. 17.Ciliate's macronucleus typically contains dozens of copies of its genome, and the genes are packaged in smaller units, each bearing many duplicates of just a few genes. 18.Based on molecular systematics, the clade of protists Alveolata includes dinoflagellates, apicomplexans, and ciliates. 19.Methanogens that are classified in domain Bacteria use CO2 to oxidize H2, releasing methane as a waste product. 20.The proposed ancestors of mitochondria in eukaryotic cell were aerobic autotrophic prokaryotes. 二、填充題(48分)：以正確英文術語作答者，每格3分；以正確中文術語作答者，每格1分 1._____ are protein molecules that assist the proper _____ of other proteins. 2.Eukaryotic cells arose from _____ and _____ between prokaryotes. 3.The nutrition mode of _____ are _____, which are the first prokaryotes that generated O2 and thus changed the young Earth. 4.Apicomplexans in the genus _____ cause malaria and have a two-host life cycle, their sexual reproductions are proceeded in the _____ hosts. 5.Among levels of biological organization, _____ consist of all the living things in a particular area, along with all the nonliving components of the environment. And individual living things are called _____. 6.The attraction of a particular kind of atom for the electrons of a covalent bond is called its _____. The _____ of water molecule results in hydrogen bonding. 7.Structures of the following functional groups are: amino(ionized) _____; phosphate _____. 8.Phospholipids are arranged in a _____ structure at the surface of a cell, their hydrophilic heads are on the outside of this structure in contact with the _____ solutions inside and outside the cell. 三、問答題(15分)：請各舉一例分別說明細菌如何對人類造成有益和有害的影響。 請問有誰有這份考古題的解答???? 這個題目大家看看吧 大家期中考一起加油~~ --
