Industry:Natural environment
The rupture of a cell nucleus, releasing disintegrated chromatin.
Industry:Natural environment
A coral disease characterized by circular lesions with coral tisue degradation on the Caribbean elkhorn coral, Acropora palmata. The pathogen is a bacterium, Serratia marcescen.
Industry:Natural environment
A haploid cell contains a nucleus with a single complete set of chromosomes. The haploid condition is often abbreviated as n. Most fungi, protists, and algae are haploid, as are some insects, bryophytes, and the gametes of all organisms.
Industry:Natural environment

Industry:Natural environment
A sexually immature juvenile stage of an animal's life cycle. However, there are a few exceptions, where the larval form never metamorphoses into the adult stage and is sexually mature (neoteny).
Industry:Natural environment
A technique used to grow corals on artificial reefs using electricity to accrete minerals thereby cementing coral colonies to the substrate. Applying a low voltage to a metallic structure causes calcium carbonate (caco3) to build on the metal, upon which coral larvae can attach, settle and feed. This greatly speeds the coral reef growth process. The voltage is low enough that it can easily be generated by floating solar panels or from wave action .
Industry:Natural environment
An area having its original purity, not contaminated or corrupted by human intervention; the original or pure condition or state of something; unspoiled.
