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.

Reproductive isolation. Species refer to the group of organisms which share common morphological features and can interbreed and produce a viable offspring. Thus, the organisms of one species are reproductively isolated from the organisms of other species
Answer:
3.initiate repair of damaged tissues.
Explanation:
Inflammation is a process or response that occurs when the immune cells produce substances in order to protect the body from injuries infection by foreign microbes like viruses and bacteria. The main functions of inflammation or inflammatory response are to remove the cause of injuries in cell, get rid of damaged tissues and necrotic cells that might have been damaged during injury and initiate the repair of damaged tissues.
During inflammatory response certain symptoms like redness, heat/warmth, swelling and pain are most likely to be experienced.
3 examples of proteins in living organisms:
1. Collagen - maintains firmness and structure to body cells and tissues, keeping them together.
2. Keratin - creates the protective barrier for living organisms like skin, nails, and hair.
3. Globular and trans-membrane - supports the regulation of the flow of small ions and molecules such as sodium and glucose.
Mendel proposed the law of segregation and the law of independent assortment toexplain the inheritance behind his pea plant traits. A hundred years later, Boveri and Sutton developed the chromosome theory of inheritance, which stated thatchromosomes were responsible for the heredity Mendel observed.
