Answer:
mRNA that encodes multiple different polypeptide products
Explanation:
Polycistronic mRNA is a single molecule of mRNA that contains many genes, each one with its own start codon AUG, and therefore can be translated into many different polypeptides.
The polypeptide products usually have a related function, they can be either different subunits of a particular protein, or participate in a metabolic process.
Polycistronic mRNA is typically found in prokaryotes.
The best description of predictable development of plant structure in an area over time is primary succession. The correct option is a.
<h3>What is succession?</h3>
Changes in the physical environment and the population of the species cause succession. There are two types of succession: primary and secondary succession.

Huh????????????????????????
The answer is; Physical weathering by water would carve out the face of the cliff.
The bottom of the cliff would register the greatest weathering because of the force of the water hitting the rocks in the fall. As a cave is curved from the base of the cliff, the overhanging part of the cliff eventually collapses hence retracting the cliff a small distance upstream of the river. The diagram below demonstrates this;
