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:
food stuff and building materials
Explanation:
why is because the produce food stuff more than buidling materials
Answer: Phagocytosis
Explanation: this is one of the various ways in which the immune system fights against bacteria and other pathogenic organisms. It does this by extending its plasma membrane outwards forming a structure like a pseudopodia which it utilises to engulf the invading organism.
<span>Species with a high capacity for population growth like bacteria, for example,
</span><span>tend to be small because they don't wast time and their energy into growth, but rather in reproduction. They start reproducing sonly after they are born.
On the other hand, bigger species like us humans, have time to grow larger, mature in a complex organism and spend less energy and time in reproducing a lot.</span>
