Depends, if the biotic factor is a chipmunk or something of that case, its natural habitat is a rock, which is biotic. but...if the animal is something like a deer they don't need abiotic factors. its your chose to chose but I'm leaning more twords false because not ALL biotic factors cant go without an abiotic factor
The alluvial soils are somewhat enriched in Mn, Zn, Co, and Cu, which is related to the biological accumulation of these elements entering the trophic chains..
<span>The mutation did not affect amino
acid sequence or the molecular weight (no evidence of amino acid substitution
or protein truncation). Therefore, the mutation is not likely within the coding
region of the gene. Most likely the
mutation is in the regulatory region of the gene such as the promoter region.
Such mutation would interfere with transcription initiation and hence decreases
the amount of mRNA and protein produced. </span>
