How could uv light affect an organism's trait
WebUltraviolet light is radiation in wavelengths from 200 to 300 nm (nanometers) found in natural sunlight, sun lamps and tanning beds. DNA sucks in UV light like a sponge because the most intense portion of DNA’s absorption spectrum (wavelengths of 250 to 260 nm) complements the peak energy emission of UV light (240 to 280 nm). Because of the ... WebOverexposure to UV-B reduces size, productivity, and quality in many of the crop plant species that have been studied (among them, many varieties of rice, soybeans, winter wheat, cotton, and corn). Similarly, overexposure to UV-B impairs the productivity of phytoplankton in aquatic ecosystems. UV-B increases plants’ susceptibility to disease.
