Answer:
C. The pond experienced an algae bloom.
Explanation:
From the graph we see that the fish population continue to decrease with time. As time passed on, the fish population keeps suffering a decline. In retrospect, the population of the algae continued to increase.
- We can ascribe this to the pond experiencing an algae bloom.
- It could be due to condition called eutrophication.
- When nutrients become very much in water and more algae is produced.
- This leads to dissolve oxygen amount reducing in the water body.
- Therefore, fishes will die off.

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.
