A model organism (often shortened to model) is a non-human species that is ...
The diagram with three nested ellipses indicates a hierarchy between the three dimensions of sustainability: both economy and society are constrained by environmental limits The wedding cake model for the sustainable development goals is similar to the nested ellipses diagram, where the environmental dimension or system is the basis for the ...

Biology is the scientific study of life. [1] [2] [3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [1] [2] [3] For instance, all organisms are made up of cells that process hereditary information encoded in genes , which can be transmitted to future generations.
List of Apple products. This timeline of Apple products is a list of all computers, phones, tablets, wearables, and other innovation made by Apple Inc. This list is ordered by the release date of the products. Macintosh Performa models were often physically identical to other models, in which case they are omitted in favor of the identical twin.
Apple scab is a common disease of plants in the rose family that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus , Cotoneaster , and Pyrus , it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated ...
