In the radiation foundation chain, biology focuses on how absorbed energy can alter what?

Biology in this context looks at how the energy deposited by ionizing radiation affects living matter. The central idea is that absorbed energy can cause chemical changes in critical molecules—DNA, proteins, membranes—and disrupt cellular function. That disruption can lead to cell injury or death, tissue damage, and eventual effects on organs. So the focus is on how energy deposition translates into changes at the cellular, tissue, and organ levels. The other options describe purely physical or optical properties: how fast electrons move in a vacuum, how tissue appears color-wise under light, or how energy is absorbed by bone. These do not address the biological response to absorbed energy, which is why the correct emphasis is on alterations to cells, tissues, and organs.
