Answer:
Polycistronic mRNAs
Explanation:
Normally In Eukaryotic cells the messenger RNAs (mRNA) only contain the information to produce a protein, these mRNAs are known as monocistronic.
In Prokaryotes, the transcription system is usually polycistronic, this means that a mRNA have the information to encode two or more genes.
As an interesting example of the co-evolution of Eukaryotes, the mitochondrial genome has polycistronic genes.

The moon is directly in between the Sun and Earth.
The answer is; A
This model hypothesizes how life started during the early conditions of the earth which were hot and filled with greenhouse gases in its atmosphere about 4 billion years ago. It is explained by the theory of spontaneous generation where organic molecules were created from inorganic molecules spurred from energy from lightning. These organic molecules filled the water bodies and chemically arranged themselves, over time, into primordial life.
Some parts of the ocean never receive sunlight.
