A disease in which the organism produces antibodies against its own tissues.
Industry:Natural environment
A toxic substance which interferes with the electrical activities of nerves and inhibits, damages or destroys the tissues of the nervous system, especially neurons (nerve cells) .
Industry:Natural environment
An echinoderm characterized by radial symmetry, and usually with five arms (rays) radiating from a central body. Minute pincer-like structures on the arms, called pedicellaria, ensure that the surface of the arms stay free from algae. There are a few sea stars that have 6 or 7 arms, and some with even more. Injuries will also cause more arms to grow. The majority of sea stars are carnivorous and feed on sponges, bryozoans, ascidians and mollusks. Other are detritus feeders or scavengers. Some sea stars, for example the crown-of-thorns that feeds on coral polyps, are specialized feeders; also called "starfish" .
Industry:Natural environment
Offspring from the same parental group going through their life cycle together.
Industry:Natural environment
An electronic device that uses organic molecules to form a semiconductor; a microchip that uses tiny strands of DNA to latch onto and quickly recognize thousands of genes at a time; collection of miniaturized test sites (microarrays) arranged on a solid substrate that permits many tests to be performed at the same time in order to achieve higher throughput and speed. A biochip can perform thousands of biological reactions, such as decoding genes, in a few seconds. Biochips can also be used to rapidly detect chemical agents used in biological warfare so that defensive measures can be taken.
Industry:Natural environment
The smallest component of an element, made up of neutrons, protons, and electrons.
Industry:Natural environment
Energy that comes from a source and travels through some material or through space. Light, heat and sound are types of radiation.
Industry:Natural environment
Reproduction that does not involve the union of sex cells (gametes) to produce a zygote. Examples in corals are budding and fragmentation.
