1. Cryopreservation is, simply put, flash freezing a biological tissue or organism in liquid nitrogen (N2).
2. the application of sufficient Ni sprays. Urease splits urea hydrolytically into ammonia (NH3) and carbon dioxide (CO2). Urea [CO(NH2)2]
3. little-leaf of mango can be considered a zinc deficiency disease comparable/ size reduction of young leaves caused by Zn deficiency
4. Grasshoppers, roaches, and other insects have a similar system for determining the sex of an individual. Adult males lack a Y sex chromosome and have only an X chromosome.
5. Nalidixic acid (tradenames Nevigramon, Neggram, Wintomylon and WIN 18,320) is the first of the synthetic quinolone antibiotics.
6. Nystatin is a polyene antifungal drug to which many molds and yeast infections are sensitive, including Candida.
7. klendusity
8. A special kind of disease escape in which a susceptible plant avoids disease because of an intrinsic property of the plant itself that greatly reduces the chances of its being inoculated, even though there may be an abundance of inoculum in the area.

12. Down syndrome, or Down's syndrome (primarily in the United Kingdom), trisomy 21
13. Earth’s oldest fossils are the stromatolites consisting of rock built from layer upon layer of sediment and other precipitants.[3] Based on studies of now-rare (but living) stromatolites (specifically, certain blue-green bacteria), the growth of fossil stromatolitic structures was biogenetically mediated by mats of microorganisms through their entrapment of sediments.
