The correct answer is - C. Hydrosphere; geosphere.
The hydrosphere is the sphere which contains all the waters on the planet Earth. The geosphere is the sphere that contains the solid rocky part of the Earth. When the water goes through the porous sediments and enters deeper into the ground, that means the we have an interaction of water and rocks. In other words, since the water is part of the hydrosphere, and the rocks are part of the geosphere, we have an interaction between the hydrosphere and the geosphere.
A polyribosome (or polysome) is a complex of one mRNA molecule and two or more ribosomes that form a polypeptide chain during active translation. Since multiple ribosomes can translate mRNA simultaneously, many polypeptides can be produced simultaneously from a single mRNA.
<h3>Role of all molecular constituents present in a functional polyribosome ;</h3>
1. mRNA: contains the codon
2. tRNA : contains the anticodon for the mRNA
3. Ribosome (large & small subunits): facilitates interaction between mRNA and tRNA
4. Amino acids:
5. Initation Factors: proteins important in the interaction/binding of the small subunit, mRNA, TRNAmet, and the Shine Dalgarno sequence
7. Elongation Factors: bring charged tRNA's to the A site of the ribosome
8. GTP: provides energy
Ribosome recruitment in eukaryotes occurs when the eukaryotic initiation factor e1F4F and poly(A) binding protein (PABP) recognize 5′-capped mRNAs and recruit the 43S ribosome complex to this site. increase. In addition, the Kozak consensus sequence ACCAUGG is also required for translation initiation. Therefore, at first glance, it seems unlikely that overlapping sequences will be translated.

Opportunity cost
Opportunity cost is the benefit, profit or value that could have been received or obtained but instead given up in favor of another alternative or course of action. Every situation has several alternatives and every resource has several alternative uses as well. Thus, every decision comes with it an opportunity cost. <span>
