  2. Oligophagy - Wikipedia

    en.wikipedia.org/wiki/Oligophagy

    Oligophagy refers to the eating of only a few specific foods, and to monophagy when restricted to a single food source. [1] The term is usually associated with insect dietary behaviour. [ 2 ] Organisms may exhibit narrow or specific oligophagy where the diet is restricted to a very few foods or broad oligophagy where the organism feeds on a ...

    This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.

  4. Transmembrane protein - Wikipedia

    en.wikipedia.org/wiki/Transmembrane_protein

    For example, the "unfolded" bacteriorhodopsin in SDS micelles has four transmembrane α-helices folded, while the rest of the protein is situated at the micelle-water interface and can adopt different types of non-native amphiphilic structures. Free energy differences between such detergent-denatured and native states are similar to stabilities ...

    Below are some documented examples of oligotrophic environments in Antarctica: Lake Vostok, a freshwater lake which has been isolated from the world beneath 4 km (2.5 mi) of Antarctic ice is frequently held to be a primary example of an oligotrophic environment. [7] Analysis of ice samples showed ecologically separated microenvironments.

    The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.

  7. Cell potency - Wikipedia

    en.wikipedia.org/wiki/Cell_potency

    Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...

  8. Optimality model - Wikipedia

    en.wikipedia.org/wiki/Optimality_model

    In biology, optimality models are a tool used to evaluate the costs and benefits of different organismal features, traits, and characteristics, including behavior, in the natural world. This evaluation allows researchers to make predictions about an organism's optimal behavior or other aspects of its phenotype .
