The
zebrafish lineage is the studied gene who evolved most rapidly as shown in its
branch where it manifest to have the longest lineages.<span> The changing branch lengths indicates
that the gene has evolved at different rates in each lineages and the branch length
is proportional to amount of the genetic variation in each linear.</span>

The correct answer is 3:1
1 - The most common emission and byproducts that are generated by burning coal are carbon dioxide, nitrogen oxides and dioxides and CCPs in genearl (coal combustion products).
2 - Mercury is a heavy liquid metal with some toxical properties. When ingested (most commonly trough water) can be fatal [for further info search Mercury Poisoning]. Something I should also point out is that most of the contaminated water sources are residual waters.
Hope it helped,
Happy homework/ study/ exam!
