If all of the decomposers were suddenly removed, then nutrients would not be able to cycle back into the soil so that nutrient uptake by producers could be achieved, or at least not as fast or at as great a level, as it would probably soon enough become inorganic and unusable. Nutrients would be rapidly lost in the ecosystem and would not be able to be put back into the system.
Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.

Explanation:
The correct answer is solute. I'm pretty sure
Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
