1.D infrared Light
2.D 730
3.C FM because the frequency is higher
4.B No, because the body repairs damaged cells
5.A They predict the severity of the exposure for treatment
A. Yes, because it is always present
B. No, because it is natural
C. No, because the body repairs damaged cells
D. Yes because the body can't repair damaged cells

3.C FM because the frequency is higher
4.B No, because the body repairs damaged cells
5.A They predict the severity of the exposure for treatment
7. D X-rays
8. B wavelength
9. C ultraviolet radiation
10. A ionizing radiation
The correct answer to the question is C. No, because the body repairs damaged cells.
Natural radiation, in moderate amounts, is not considered dangerous to humans because our bodies have evolved to repair any damage that may occur. The human body has sophisticated mechanisms to repair damaged cells and DNA. Commonly referred to as DNA repair mechanisms, these processes help our cells recover from the effects of radiation exposure by fixing or eliminating any damaged genetic material.
Therefore, exposure to natural radiation on Earth is generally not harmful as long as it is within safe and regulated limits. It is important to note that excessive exposure to any form of radiation, whether natural or man-made, can have adverse health effects. However, for the average person, the levels of natural radiation we encounter on Earth are not typically an immediate cause for concern.
