The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule). (https://en.wikipedia.org/wiki/Radicle)
A substance undergoing spontaneous decay or disintegration of atomic nuclei and giving off radiant energy in the form of particles or waves, often associated with an explosion of a nuclear weapon or an accidental release from a nuclear power plant, holding facility or transporting container. (https://www.eionet.europa.eu/gemet/en/concept/6915)
The phenomenon whereby atoms undergo spontaneous random disintegration, usually accompanied by the emission of radiation. (Radioactive waste management glossary : 2003 ed. — Vienna : InternationalAtomic Energy Agency, 2003 https://www-pub.iaea.org/MTCD/publications/PDF/Pub1155_web.pdf)
Quick-frozen foodstuffs or deep-frozen food products are those subjected to the ‘quick-freezing’ process, in which the temperature zone of maximum crystallisation is spanned as rapidly as possible and the product is then held (after thermal stabilisation) at a temperature of – 18 °C or lower. (Adapted from https://eur-lex.europa.eu/EN/legal-content/summary/quick-frozen-food.html and XC 8-1976 Code of Practice for the Processing and Handling of Quick Frozen Foods)
Thaumatococcus daniellii is a plant species from Africa, known for being the natural source of thaumatin, an intensely sweet protein which is of interest in the development of sweeteners. (https://en.wikipedia.org/wiki/Thaumatococcus_daniellii)
Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system.

Observed following a perturbation to an equilibrium point, hysteresis is when the return trajectory to the original equilibrium point or state is different than the outgoing trajectory. In ecological terms, this often means that the "work" that must be done to return to an original state after a disturbance is much more than the "work" done by the original perturbation itself. Hysteresis is a characteristic of alternative stable states and can be used to identify their presence because it means that more than one state can be observed under identical environmental conditions — at least over some range of conditions. (Beisner, B. E. (2012) Alternative Stable States. Nature Education Knowledge 3(10):33. https://www.nature.com/scitable/knowledge/library/alternative-stable-states-78274277/)
Note
Hysteresis can be found in ecology, economics, physics, chemistry, engineering, and biology.
An extensive, flat or gently sloping region, usually found at depths greater than 4000m. (https://www.gebco.net/data_and_products/undersea_feature_names/documents/b6_ef_e4.1.0_2013_rev2017.pdf)

Branch of pisciculture specialized in the propagation and the rearing of catfish. (Adapted from Huet, M. (1986) Textbook of fish culture. Breeding and cultivation of fish. Farnham, Surrey, England, Fishing News Books Ltd. 438 p. 2nd ed.)
Raffinose is a trisaccharide composed of alpha-D-galactopyranose, alpha-D-glucopyranose and beta-D-fructofuranose joined in sequence by 1->6 and 1<->2 glycosidic linkages, respectively. It has a role as a plant metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a raffinose family oligosaccharide and a trisaccharide.
