Question

which waves can increase the risk of cancer? radio and microwaves ultraviolet and gamma gamma and visible light infrared and x-rays

Explanation:

Ultraviolet (UV) rays from the sun and gamma rays (ionizing radiation) can damage DNA in cells. When DNA is damaged, it can lead to mutations. If these mutations affect genes that regulate cell growth and division, it can potentially lead to cancer. Radio, microwaves, infrared, and visible light are non - ionizing radiation and do not have enough energy to directly damage DNA in a way that causes cancer. X - rays are also ionizing radiation but in the given options, "Ultraviolet and Gamma" is the correct pair as it combines two types of ionizing (gamma) and a known carcinogenic non - ionizing (UV, due to its high energy in the non - ionizing range) that can damage cells over time.

Answer:

Ultraviolet and Gamma
