Answer: high
Explanation:
When the supply of labor for a particular occupation is high, this means that there are plenty people who are ready to work and there's surplus labor. When the need for workers arise by employers, due to the high labor supply, there'll be lower wages that'll be offered to them.
On the other hand, when the number of workers that we have in an occupation is limited and the demand for such workers is high, this will bring about a scenario whereby the wages that'll be offered to such workers will be high because there's a high demand for them and there are limited workers for that occupation.
The chemical structure of adenine only allows it to form a hydrogen bond with thymine. While the structure of guanine allows it to form a hydrogen bond with cytosine. DNA Polymerase will then proofread a strand of DNA to ensure there is no mismatching bases.
