<span>The question says,'decomposition of plants and animal matter present in the soil is largely due to soil micro organism. The statement is true. The soil microbes function by decomposing the organic matter in the soil to the forms usable to plants. The humus produce by these microbes is largely responsible for soil fertility. </span>
A phylogeny of the same taxa based only on morphological traits:
Some highly conserved genetic sequences can result in unrelated species appearing closely related in a molecular phylogeny, and not reflect the same pattern as the morphologic phylogeny.
Gene sequence changes may not result in morphological changes.
Gene sequences always provide more data than morphological traits.
Morphological analyses always provide more data because each morphological trait is the result of the expression of many genes.
The molecular data may be based on the analysis of introns, which aren't expressed and don't contribute to the evolutionary history of a group of taxa.
Why is molecular data more accurate?
Phylogenetic trees reconstructed from molecular sequences are often considered more reliable than those reconstructed from morphological characters, in part because convergent evolution, which confounds phylogenetic reconstruction, is believed to be rarer for molecular sequences than for morphologies

Answer:
Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Explanation:
Answer:
monoallelic gene expression
Explanation:
<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>
A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.
When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.
