Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
The correct answers for this question are these:
<span>What could happen if the DNA replication process encounters an error while coding?
- An acquired mutation would occur.
- No noticeable errors would occur to the organism because not all DNA codes for proteins.
- DNA would convert into RNA.
- A mutated trait could be exhibited</span>

In ponds where it lives, the northern leopard frog is probably a significant indicator of the water's quality. This species is an essential component of the food chain, and tadpoles, which are the main eaters of algae in ponds, can have a big impact.
<h3>What distinguishes tree frogs from other frog species?</h3>
These frogs are most easily recognized by their feet, which have claw-shaped toe bones as their last bone. They can also climb trees thanks to toe pads with small suction cups and extraskeletal structures on their toes. They are available in a number of hues, the most popular being green, gray, or brown.
