Petunia. Petunias come in dozens of different colors, of course, and are a staple flower for hanging baskets and window boxes. Add a few black blooms for some serious drama. Hardiness Zones: USDA ...
It includes 847 life-size models (representing 780 species and varieties of plants in 164 families) and some 3,000 detail models such as of plant parts and anatomical sections. The collection comprises approximately 4,400 individual glass models representing over 830 plant species.

In atomic physics, the Bohr model or Rutherford–Bohr model was the first successful model of the atom. Developed from 1911 to 1918 by Niels Bohr and building on Ernest Rutherford 's nuclear model , it supplanted the plum pudding model of J J Thomson only to be replaced by the quantum atomic model in the 1920s.
English: Diagram of an idealized Lithium atom, primarily useful to illustrate the nucleus of an atom. This sort of design is scientifically inaccurate in many important respects, but serves as a powerful mandala of the nuclear age. Inspired by drawing from User:Fastfission, recreated by User:AG Caesar in vector/svg format.
The model shown to the left represents a ball-and-stick model of proline. The balls have colours: black represents carbon (C); red, oxygen (O); blue, nitrogen (N); and white, hydrogen (H). Each ball is drilled with as many holes as its conventional valence (C: 4; N: 3; O: 2; H: 1) directed towards the vertices of a tetrahedron. Single bonds are ...
