  2. SAT Subject Test in Biology E/M - Wikipedia

    en.wikipedia.org/.../SAT_Subject_Test_in_Biology_E/M

    The SAT Subject Test in Biology was the name of a one-hour multiple choice test given on biology by the College Board. A student chose whether to take the test depending upon college entrance requirements for the schools in which the student is planning to apply. Until 1994, the SAT Subject Tests were known as Achievement Tests; and from 1995 ...

  3. Co-adaptation - Wikipedia

    en.wikipedia.org/wiki/Co-adaptation

    In biology, co-adaptation is the process by which two or more species, genes or phenotypic traits undergo adaptation as a pair or group. This occurs when two or more interacting characteristics undergo natural selection together in response to the same selective pressure or when selective pressures alter one characteristic and consecutively alter the interactive characteristic.

  4. Canalisation (genetics) - Wikipedia

    en.wikipedia.org/wiki/Canalisation_(genetics)

    Waddington used the concept of canalisation to explain his experiments on genetic assimilation. [3] In these experiments, he exposed Drosophila pupae to heat shock. This environmental disturbance caused some flies to develop a crossveinless phenotype.

  5. Exaptation - Wikipedia

    en.wikipedia.org/wiki/Exaptation

    Exaptation or co-option is a shift in the function of a trait during evolution. For example, a trait can evolve because it served one particular function, but subsequently it may come to serve another.

  6. Competitive exclusion principle - Wikipedia

    en.wikipedia.org/wiki/Competitive_exclusion...

    In ecology, the competitive exclusion principle, [1] sometimes referred to as Gause's law, [2] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values. When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term.

  7. Biological interaction - Wikipedia

    en.wikipedia.org/wiki/Biological_interaction

    The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.

  8. Coevolution - Wikipedia

    en.wikipedia.org/wiki/Coevolution

    In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution .

  9. Concanavalin A - Wikipedia

    en.wikipedia.org/wiki/Concanavalin_A

    Concanavalin A (ConA) is a lectin (carbohydrate-binding protein) originally extracted from the jack-bean (Canavalia ensiformis).It is a member of the legume lectin family. It binds specifically to certain structures found in various sugars, glycoproteins, and glycolipids, mainly internal and nonreducing terminal α-D-mannosyl and α-D-glucosyl groups.
