Final answer:
The only organizational level of life that can become genetically adapted to its environment is the organism. Populations, cells, and tissues do not have this capability.
Step-by-step explanation:
The only organizational level of life that can become genetically adapted to its environment is the organism.
Populations are made up of multiple organisms, so while individuals within a population can exhibit genetic adaptations, the population as a whole cannot. Cells are the basic unit of life, but they do not possess the ability to adapt genetically. Tissues are groups of cells that work together, but they are not capable of genetic adaptation either.
