Answer:
The frozen ground does not allow roots for large trees to grow
Explanation: characteristic of *severe cold climate regions* *especially treeless artic regions* and high mountain tops. Plant life must adapt itself to a *short growing season(e.g,shrubs and low lying plants adapt themselves to short growing season)* of about 60 days and to a soil that remain frozen for most of the year. Most tundra regions are covered with bogs, marshes, ponds and a spongy mat of decayed vegetation, although high tundras may be covered with only lichens and grasses. Vegetation of dwarf woody plants, grasses, sedges and lichens may be quite profuse in tundra despite the thin soil and short growing season.
Therefore, large trees cannot allow roots for large trees to grow in frozen ground but short shrubs and low lying plants can,to an extent .

Explanation:
Mutation creates entirely new alleles in a population random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
DNA stands for deoxyribonucleic acid. RNA stands for ribonucleic acid. Both RNA and DNA contain Adenine, Cytosine, and Guanine. However, DNA's nitrogenous base is Thymine while RNA's nitrogenous base is Uracil.
