Answer:
Negatively repressible.
Explanation:
A control which occurs through repressor is known as negative control which may be inducible or repressible.
When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.
But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.
- Bacteria can reporduce both Outside the host as well as inside the host and they are made of cells.
- Virus can only reproduce inside the host and outside they are almost dead.They are not made of cells
So
viruses are not considered as living
Enzymes are meant to break down food in the mouth making it easier to consume and the food and gather the nutrients inside
Montreal Protocol is the correct answer I think
