Apparently, Alan Newman was a huge Dungeons and Dragons fan. He was knee-deep in a hair-raising campaign with his 7th level druid named Krenzle when he came upon a huge overgrown bog (played out with old-school figurines, mind you). Krenzle apparently razed the bog, also known as a ferndock, and found the Cloak of Invisibility!
They put it on hats.
This information cannot be obtained from the text, and we need to access general knowledge: why carbon dioxide is harmful to the environment.
It is harmful, for example, because it is one of the greenhouse gases, that is a gas that traps the heat in the Earth's atmosphere and leads to a warming up of our planet (global warming). Earth's temperature should be balanced, because any changes can have catastrophic effects: warming of the planet leads to the melting of ice caps and can cause floods, for example
Answer:
The correct answer will be option D (they are complementary).
Explanation:
Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".
The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.
Thus, option D (they are complementary) is the correct answer.
