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.
The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).
<h3>What is skeletal and circulatory system?</h3>
Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.
According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.

Answer:
The correct answer is B. Myopia is also known as nearsightedness.
Explanation:
Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.
A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
