A disadvantage of coal to liquid production of synthetic fuels is THAT IT REQUIRES MORE COAL MINING.
The coal to liquid production of synthetic fuels involves the conversion of solid coal to liquid fuel.This can be done either directly or indirectly through chemical processes. The process has many advantages, including: improvement in national and economic security, less dependence on foreign oil, provision of some environmental benefits, such as cleaner oil. But one disadvantage of this process is that it requires extensive coal mining.

None of these.
Explanation: The plants like cycads and ginkgos have swimming sperms. they need water to complete their life cycle.
There are many adaptations seen in the plants like liveworts, ferns and mosses in which they require water to complete its life cycle. This adaptation is not only restricted upto cyptograms. This can also be seen in the plants like ginkgos and cycads. Their sperms are very strange.
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.
