into nitrate which is the most usable form of nitrogen in the soil. Nitrate is absorbed by the roots of the plants, from plants nitrogen reaches to animals when they eat plants.
Here the question is stating about the hot deserts.
Hot deserts are characterized by extremely hot and arid climate.
Average annual range of rainfall is as low as 25 cm.
Deserts lack vegetation except at some patches.
Plants that survive in hot deserts have several adaptation to check the loss of water through transpiration.
These adaptation include, succulent stems, cuticularized epidermis, Reduction of leaves into spines or thorns, stems modified into phylloclades and deep roots to absorb water.
Codon refers to nucleotide triplets of mRNA that serve to specify the amino acid sequence of proteins. There are total 64 genetic code that specify 20 standard amino acids found in proteins. All codon together make genetic code. For example: AUG is codon that specify amino acid "methionine". AUG codon also serve as initiation codon during initiation of protein synthesis.
