Answer:
An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.
Explanation:
In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.
For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.

Answer:
Here are the options to complete the question
A. Fenestrated capillaries
B. continuous capillaries
C. sinusoids
D. anastomoses
A. Fenestrated capillaries is our Sure ANSWER
Explanation:
Fenestrated capillaries (is located wherever active capillary absorption or filtration occurs)
The renal glomerulus - a network of capillaries - can be identified as fenestrated capillaries aiding the diffusion of small molecules and small amount of protein into the blood stream.
