Malphigian tubules - specialized structures in insects and spiders that absorb water and ions then pass it to the gut.
Antennal glands - found in crustaceans like crabs and shrimps. Functions in reabsorption of substances, secretion and removal through urine.
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.
