The correct answer is: B) continuous transcription of the structural gene controlled by that regulator
A regulatory gene is gene that encodes for a protein, such as a repressor (or activators) that controls the transcription of another gene or group of genes.
The regulatory gene of a repressible operon encodes for the repressor that inhibits gene transcription. So, when that repressor isn’t active, transcription occurs continuously.
there would be no ecosystem
Answer:
Blood type A
Explanation:
Blood type A Rh+
Antigens (on the surface of the red blood cells):
A indicates there are A antigens.
Rh+ indicates there are Rh antigens.
Antibodies (in the blood plasma):
B antibodies.
If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Answer:
Radioactive waste, which can be very bad for humans and cause cancer.
