[ 1] The pattern is most commonly created with a warp-faced satin weave and the ground with a weft-faced or sateen weave. [ 2] Fabrics used to create damasks include silk ...
An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms. Autotrophs produce complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, [ 1] generally using energy from light or ...
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype, [ 1][ 2][ 3] and can be found by looking at the chromosomes through a microscope.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or ...
Humans are among the longest living land mammals. [ 97] Jeanne Calment, a French woman, lived to the age of 122 years, 164 days, making her the oldest fully documented human who has ever lived. She died on August 4, 1997. [ 98] Jiroemon Kimura (†116 years, 54 days), a Japanese man, died on 12 June 2013.
Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide) to organic compounds. These organic compounds are then used to store energy and as structures for other biomolecules. Carbon is primarily fixed through photosynthesis, but some organisms use ...
The study of the history of clothing and textiles traces the development, use, and availability of clothing and textiles over human history. Clothing and textiles reflect the materials and technologies available in different civilizations at different times. The variety and distribution of clothing and textiles within a society reveal social ...
African wax prints, Dutch wax prints[ 1][ 2] or Ankara, [ 3] are a type of common material for clothing in West Africa and Central Africa. They were introduced to West and Central Africans by Dutch merchants during the 19th century, who took inspiration from native Indonesian designs. [ 4] They began to adapt their designs and colours to suit ...
