Answer

advanced ex situ conservation of biodiversity.

Explanation

Solution

Cryopreservation is an advanced method of ex situ conservation. It involves preservation at -196 o C in liquid nitrogen. It can maintain tissue culture, embryos, animal cells/tissues, spermatozoa indefinitely. The cryopreserved material is revived through special technique, when required. dry weight of tobacco, with biosynthesis taking place in the roots and accumulation occurring in the leaves. Strychnine is an alkaloid plant toxin extracted chiefly from Nux vomica', formerly used as a stimulant. These are not metabolic disorder products but are metabolic wastes.
