Answer: People who have received radiation treatment are 15 times more likely to develop benign thyroid tumors relative to does who have not.
Explanation:
Relative risk of benign thyroid tumor = (52/2872)/(6/5055)
= 0.018/0.0012
= 15
Answer:
Natural Selection is an evolutionary process that caused the increment of dark-coloured Biston betularia moths in England. It happened due to increase of air pollution in the industries. The bark of the trees became darker because of the deposition of pollutants.
In order to save itself from predators, the species of Biston betularia evolved itself to a dark coloured species so that the predators gets confused between the bark of the tree and the Biston betularia.

Explanation:
The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
