Answer:
They can be produced at low cost
Explanation:
In comparison to several other manufacturing materials, some synthetic polymers such as plastics are more durable cost effective, flexible, faster to produce and reliable With regards to the cost comparison, the resins used for plastic are cheaper to obtain than mining for materials such as metals. In all quantities, it is cheaper to produce and manufacture plastics than to produce metals. Due to the light weight and corrosion resistance of plastics, it is cheaper to store and transport plastics to several locations with different environment without the plastic requiring much effort for transportation or being affected by corrosion.

Answer:
Transcription is the second step in central dogma of molecular biology. First step is replication, second is transcription, and third is translation.
In the transcription phase, DNA, which is already replicated, is transcribed to mRNA which is required to make proteins in the translation phase. The root words say it is a combination of "across" and "write". This means that DNA is going to be written in a new language "mRNA". So, this term has been used in biological process because it is the re-writing across the whole DNA to make a completely new strand of mRNA.

Anatomical terminology. Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
<em>If</em><em> </em><em>a</em><em> </em><em>cell's</em><em> </em><em>mitochon</em><em>dria</em><em> </em><em>was</em><em> </em><em>to</em><em> </em><em>stop</em><em> </em><em>working</em><em>,</em><em> </em><em>energy</em><em> </em><em>would </em><em>not</em><em> </em><em>be</em><em> </em><em>produced</em><em>.</em>
<em>This</em><em> </em><em>is</em><em> </em><em>so</em><em> </em><em>because</em><em> </em><em>The</em><em> </em><em>Mitochondria</em><em> </em><em>as</em><em> </em><em>part</em><em> </em><em>of </em><em>the</em><em> </em><em>cell</em><em> </em><em>is</em><em> </em><em>the </em><em>power</em><em> </em><em>house</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>cell</em><em>,</em><em> </em><em>it</em><em> </em><em>produces</em><em> </em><em>or</em><em> </em><em>gives</em><em> </em><em>energy</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>cell</em><em> </em><em>so</em><em> </em><em>if</em><em> </em><em>were</em><em> </em><em>to</em><em> </em><em>stop</em><em> </em><em>working</em><em>,</em><em> </em><em>energy </em><em>will</em><em> </em><em>not</em><em> </em><em>be </em><em>produced</em><em>.</em>
