Answer:b. an mRNA transcript to which multiple ribosomes are attached
Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.
Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.

Natrual variations i think
Answer:
Here, is the question with the explanations to pick from to complete the question
Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explanation why animal species richness is also high in tropical rainforests?
Animals are unable to adapt to climate variability in higher latitudes.
Animals have had the same amount of time to evolve in rainforest areas as trees.
Animal diversification rates are higher than those of trees.
Animals have diversified into the vast number of niches provided by tree diversity
The last option is the most reasonable one
Our answer is:
Animals have diversified into the vast number of niches provided by tree
Explanation:
The reason is that a lot of species are highly specialized to occupy a particular niche. Where that favourable niche exists, the population of that species increases as its offspring colonize new areas.
