Many of the known plant defense compounds primarily defend against consumption by insects, though other animals, including humans, that consume such plants may also experience negative effects, ranging from mild discomfort to death. Many of these poisonous compounds also have important medicinal benefits. [3]
Blue pigments are natural or synthetic materials, usually made from minerals and insoluble with water, used to make the blue colors in painting and other arts. The raw material of the earliest blue pigment was lapis lazuli from mines in Afghanistan, that was refined into the pigment ultramarine. Since the late 18th and 19th century, blue ...
The name of this galaxy is based on a Redshift (z) measurement of nearly 7 (actually, z = 6.604). [ 5 ] Galaxy Cosmos Redshift 7 is reported to be the brightest of distant galaxies (z > 6) and to contain some of the earliest first stars ( first generation ; Population III ) that produced the chemical elements needed for the later formation of ...
The earliest known blue dyes were made from plants – woad in Europe, indigo in Asia and Africa, while blue pigments were made from minerals, usually either lapis lazuli or azurite, and required more. [63] Blue glazes posed still another challenge since the early blue dyes and pigments were not thermally robust.

Egyptian blue, also known as calcium copper silicate (CaCuSi 4 O 10 or CaOCuO (SiO 2) 4 (calcium copper tetrasilicate)) or cuprorivaite, [1] is a pigment that was used in ancient Egypt for thousands of years. It is considered to be the first synthetic pigment. [2] It was known to the Romans by the name caeruleum.
Mutation breeding. Mutation breeding, sometimes referred to as " variation breeding ", is the process of exposing seeds to chemicals, radiation, or enzymes [ 1][ 2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
