Answer:
mRNAs are made from genes
Explanation:
Messenger RNA (mRNA) is formed with the process of transcription.  
During the process of transcription, double stranded DNA which contain genes are converted into mRNA with the help of enzyme RNA polymerase, so, mRNA are made from genes.
The single stranded mRNA which corresponds to the genetic sequence of a gene allows the ribosome to produce protein (Translation).
Hence, the relation between mRNA ns genes is that mRNA ar emade from genes.

Answer:
Denitrification process occurs when the soil bacteria use nitrate for the respiration of oxygen in the air. These nitrates are converted to nitrogen gases.  
<u>Explanation:
</u>
<em>The denitrification process mostly occurs in warm nature rapidly, wet soils with sufficient of nitrate. Denitrification process only occurs when the nitrate is present.</em> <em>The denitrification is in sewage treatment and it is beneficial process, the problem considered in agriculture farmers to increase their crop yields because they are applying nitrogen fertilizers to the land. </em>
<em>Denitrification process increases from cropland and it is responsible for increases the amount of nitrous oxide in the atmosphere.  The denitrification process plays an important to recycling of nitrogen for healthy soil, microbial and for plant growth, and animal’s health.</em> The impacts of global warming are due to the process of denitrification through loss of nitrous oxide.

Answer:
Explanation:
Knowledge it expected that an individual have the ability to recall some specific terms,facts,methods, processes, pattern, structure, or setting of a thing without necessarily understanding the concept.
Comprehension is the understanding an individual knows or get from what is being communicated and the ability to make use of the idea that is been communicated without seeing the full expression if it. 
Comprehension is the explanation and understanding of knowledge i.e what is known and can be recalled.
