Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites
They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day, ultimately reaching 30 to 80 metres (100 to 260 ft). [ 7 ] Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate).
Lutefisk ( Norwegian, pronounced [ˈlʉ̂ːtfɛsk] in Northern and parts of Central Norway, [ˈlʉ̂ːtəˌfɪsk] in Southern Norway; Swedish: lutfisk [ˈlʉ̂ːtfɪsk]; Finnish: lipeäkala [ˈlipeæˌkɑlɑ]; literally " lye fish") is dried whitefish, usually cod, but sometimes ling or burbot, cured in lye.

An aeroponic greenhouse is a controlled environment structure made of glass or plastic, equipped with the necessary tools to cultivate plants in an air/mist environment. Aeroponic conditions pertain to the specific environmental parameters required to sustain plant growth in an air culture, tailored to the needs of a particular plant species.
Evolutionary history of plants. A late Silurian sporangium, artificially colored. Green: A spore tetrad. Blue: A spore bearing a trilete mark – the Y -shaped scar. The spores are about 30–35 μm across. The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved ...
The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
Tillandsia is a genus of around 650 species of evergreen, perennial flowering plants in the family Bromeliaceae, native to the forests, mountains and deserts of the Neotropics, from northern Mexico and the southeastern United States to Mesoamerica and the Caribbean to central Argentina. Their leaves, more or less silvery in color, are covered ...
