I think an example would be, Humans are larger than they were 100 years ago. This is not a genetic characteristic .Phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior and products of behavior. The Genotype on the other hand is the genetic make up of an organism.
It comes from the Greeks and that’s it’s a controversial meaning that’s literally all ik lol hope it helps
Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.
