Answer: D) cAMP
Explanation:
In the absence of glucose cell can make use of other sources of carbohydrates such as lactose. In E. Coli and other bacteria utilization of lactose depends on the availability of cAMP. Bacteria accumulate cAMP only when starved. When glucose is exhausted, cAMP is available in plenty.
cAMP is necessary for the gene expression because it binds catabolite repressor protein (CAP) to form CAP-cAMP complex. CAP is a lac repressor the binds to the operator site of the lac operon preventing RNAP From binding to the promoter.
RNA polymerase can bind to the promoter site only when CAP-cAMP formed

According to the stability-diversity hypothesis, tropical rain forests are stable communities because they have high species richness. Thus, the correct option is A.
<h3>What is Species richness?</h3>
Species richness may be defined as a count of the number of species living in a community at a particular time.
The tropical rainforest has a stable climate with moderate rainfall. So, species richness and diversity have been found in this biome.
Therefore, the correct option for this question is A.
