The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.
In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.

Answer:
Active transport
Explanation:
The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.
We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.
It cannot be endocytosis or exocytosis, as there are no vesicles.
Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.
Based on the given situation above, when there is this strong feeling that you want to choose one over the other, which is, for example choosing which colleges to attend, the part of the brain that is at work is the emotional brain.
Yes it's ture hope this helps tell me if i'm i right or wrong
