  SAT2考試是SAT subject test的通常說法,SAT2考試有別于SAT1,它是一種專項考試,考察學(xué)生某一科目的能力。下面澳際小編搜集整理了SAT2生物考試專業(yè)詞匯中以字母F打頭的詞匯,希望能夠幫助大家更好地備考SAT2生物考試。

  F1 generation

  The first generation of offspring from a cross between two varieties or individuals. In Mendel’s experiments, all the F1 offspring were heterozygous hybrids with a dominant phenotype.

  F2 generation

  The second generation of offspring in a breeding experiment; the offspring from a mating between two F1 hybrids. In Mendel’s monohybrid experiments, the ratio of dominant to recessive phenotypes in the F2 generation was 3:1.

  facilitated diffusion(促進擴散)

  Diffusion of molecules that cannot pass through the cell membrane independently, but rather through permeable protein channels embedded in the membrane. Facilitated diffusion does not require outside energy.

  FADH2 (蛋白結(jié)合性載體)

  A molecule that stores energy for harvest by the electron transport chain.

  food chain(食物鏈)

  A linear relationship of predators and prey.

  food web(食物網(wǎng))

  Many connected food chains that exhibit the relationships of all predators to all prey constitute a food web.

  fossil record(化石記錄)

  The grouping of fossilized remains according to relative and absolute age.

  Fallopian tube(輸卵管)

  Duct that connects the ovaries with the uterus; the passage through which the ovulated egg travels from the ovaries to the uterus.

  Fermentation(發(fā)酵)

  The second stage of anaerobic respiration, which produces the NAD+ necessary for glycolysis. There are two types of fermentation: alcoholic fermentation and lactic acid fermentation. Yeast engage in alcoholic fermentation, while muscle cells lacking oxygen produce lactic acid.

  Fetus(胎兒)

  The name given to an embryo after it has developed organs.

  Flagellum(鞭毛)

  A whiplike structure projecting from the surface of some cells and single-celled organisms; coordinated waving of the flagellum allows the organism to swim. Prokaryotic flagella are made of a single helical chain of flagellin proteins; eukaryotic flagella are made of multiple chains of microtubule proteins.

  fluid-mosaic model(流動鑲嵌模型)

  Theory describing the cell membrane as a dynamic structure with proteins floating, yet partially embedded, in a sea of phospholipids.
