Decomposers can break down any dead organic matter. Since any of the organic matter consume can come from any level, there isn't a specific place for decomposers. It is hard to place them because as you travel up the food pyramid energy is lost. Decomposers would have their own level because of this.
The cAMP receptor protein (CRP) is said to be responsible for positive regulation of the lac operon because (D) CRP bound to the CRP-binding site stimulates the transcription of the lac operon.
CRP is a regulatory protein. It binds to the cAMP and causes a conformational change. This allows the CRP to bind to a specific site at the promoter region of the DNA. This then activates the transcription process.
Lac operon is a group of genes that allow the uptake of glucose in bacteria. There are four components of lac operon: regulator gene, promoter gene, operator gene and structural genes. The machinery of operon is turned on the lactose itself.

<span>A
mineral has to be naturally occurring, inorganic, solid, have a crystal
structure, and have a definite chemical composition. Coal is not a
mineral because it is carbon-based and came from fossilized plants. That
proves that it is organic and has no definite chemical composition,
defying two rules you would need to follow to be a mineral. Glass is a
non-crystalline solid. This means that the atoms are not arranged in a
regular and repeating pattern. A mineral by definition possess a
crystalline form, it has its elements arranged in a regular and
repeating pattern.</span>
Plowing with machines, irrigating with drip systems, and these are all modern agricultural methods.
