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.

Answer:
Like the human body, the bicycle relys on other things to keep moving. For example, in order for the bicycle to keep moving, the rider needs to have legs and be able to push the pedals foreward. In order to breath, the body needs to have lungs and those lungs depend on the heart to pump blood throughout the body. The lungs rely on the heart and your brething relys on your lungs. Hope this helped, brainliest always appreciated.
Explanation:
You answer to this question will be: A) Camouflage, Mimicry, and Stingers*
Answer:
The correct answer will be option C- A structure upon which proteins are assembled.
Explanation:
A ribosome is a complex molecule machine formed of proteins and rRNA molecules which acts as a site for the synthesis of the proteins.
These ribosomes are present in the cell as a free entity suspended in the cytosol or attached to the endoplasmic reticulum.
Each ribosome is made up of a large and small component which translates the information coded in the mRNA in the form of codons to amino acids which join to form proteins.
Thus, option- C is the correct answer.
