If the inducer [allolactose] is present in the negative control then it will bind to the repressor decreasing its ability to bind to the operator due to which the transcription begins again and the operon is turned on.
Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.
An inducer is a molecule that has the ability to induce or activate the operon. ex- in the case of the lac operon, allolactose acts as an inducer.
A repressor is a molecule that will repress or restricts the transcription of the genes of the operon, as a result, the operon will be switched off.
When the lac operon is under negative control, with no CAP [catabolite repressor protein] binding activity, the repressor remains active and thus binds to the operator region of the operon, as a result, no transcription takes place and the operon will be switched off.
But if the inducer will be present even in the negative control then the transcription takes place and the operon will be on.

Where on find eggs of a Bot Fly sticking to the hairs of your horse's ankles. The subfamily that these eggs likely belong to are: Gasterophilinae.
<h3>
What is Gasterophilinae?</h3>
The Gasterophilinae are a subfamily of the Oestridae that comprises huge, parasitic flies; this group was previously classified as a family, but all subsequent classifications locate them squarely within the Oestridae. Many members of this subfamily spend part of their larval lives in herbivore digestive systems.
Gasterophilus intestinalis, often known as the horse bot fly, is a species of insect in the Oestridae family that may be found all over the world. The adults, which resemble bumblebees, are most active throughout the summer.
Female botflies deposit eggs on blood-sucking arthropods like mosquitoes and ticks to reproduce. When afflicted arthropods attack a person or another mammal, larvae from the eggs are released. A botfly larva burrows into subcutaneous tissue after entering the host's skin through a bite wound or a hair follicle.
