Among the non-mammalian vertebrates, the cloaca is an anatomical structure that function as a shared pathway for the digestive, excretory, and reproductive systems. Cloaca in vertebrates, common chamber and outlet into which the intestinal, urinary, and genital tracts open. It is present in amphibians, reptiles, birds, elasmobranch fishes, and monotremes. Cloaca is not present in placental mammals or in most bony fish.
It depends on what the question is, buddy
If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that " the repressor could not bind to DNA".
<u>Option:</u> A
<u>Explanation:</u>
A DNA-binding proteins prevent gene expression coding for proteins engaged in bacterial lactose metabolism is understood as the lac repressor.
Such genes are repressed if lactose is not accessible to the cell, meaning that when lactose is available, the bacterium only spends energy in the development of machinery required for the absorption and processing of lactose.
When lactose is accessible, it is transformed into allolactose, which prevents the DNA binding ability of the lac repressor and thus increases the gene expression.
In an ecosystem, energy from the sun is transferred by way of consumption
