Answer:
The aboveground biomass of the boreal forests is high because these very slow-growing tree species are long-lived and accumulate standing biomass over a good amount of time. Species diversity is smaller than that seen in temperate forests and most tropical rain forests.

Answer:
a. Bacteria cannot carry out splicing.
Explanation:
Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.
Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.

In women that are pregnant, the effects of substances are far more adverse than they would be in a normal person, especially if the woman is taking more than one. For this reason, it is important for pregnant women to take as much care as possible of their bodies and refrain completely from smoking and drinking alcohol, as both of these activities are detrimental towards the fetus's health. Pregnant women should even avoid second hand smoke from cigarettes.
