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.
Quartz
Explanation:
Quartz is a framework silicate made up of interlocking SiO₂. It is the most resistant mineral to weathering.
This is based on the Bowen's reaction series of minerals.
From the series;
- In a given melt, quartz is the last mineral to crystallize out of solution.
- Olivine is usually the first
- Quartz being the last does not readily react with other substances.
- This makes it resistant to agent of weathering.
