Answer:
Because the promoter region is initiation sites for transcription to occur.
Explanation:
Transcription is the first process of gene expression in both eukaryotic and prokaryotic cells. Transcription involves the synthesis of a complementary RNA strand from a DNA template. It is carried out by an enzyme called RNA polymerase which binds to the DNA molecule and adds nucleotides based on the sequence it reads on the DNA.
On the DNA molecule, are sequences of nucleotides which the RNA polymerase recognizes and binds to in order for the transcriptional process to start. These sequences are called PROMOTER regions. They are located upstream i.e. after initiation site, of the DNA. Without these promoter region, RNA polymerase cannot bind to the DNA molecule and hence transcription cannot occur.

Answer;
-Parfocal
Parfocal is the word that describes a microscope that remains in focus when the objective lenses are changed.
Explanation;
Parfocal means that when one objective lens is in focus, then the other objectives will also be in focus.
Parfocalling compound microscope objectives is a procedure which allows one to adjust each objective lens so that it will remain in relative focus with the other objective lenses on the microscope when switching from one magnifcation to the next.
If you're referring to wing color in terms of evolution, wing color can be determined by something as small as the color of trees that particular bird is around. Those with wings that match the tree color are most likely to survive because they are more hidden from predators.
