<span>The answer is e. Myoglobin has a single polypeptide chain so it has 1o, 2o, 3o and 4o structure.
Myoglobin is an iron and an oxygen binding protein. It has a single polypeptide chain. Proteins with the single polypeptide chain cannot have quaternary (4o) structure. 4o structure of proteins includes an arrangement of multiple folded polypeptide chains (subunits) in a multi-subunit complex. Therefore myoglobin cannot have 4o structure as the single chain polypeptide. All other choices are correct.</span>
Answer:
A
Explanation:
Primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers.
The chromosomes in the sex cells would be half the chromosomes in the body cells; so since each body cell has 40 <span>chromosomes and half of that is 20, there's your answer. It's B. 20</span>
