Answer:
The human eye can detect up to 700 nanometers but the range adjacent to the visible spectrum is called the near infrared and the longer wavelength part is called far infrared. The region just below the visible in wavelength is called the near ultraviolet. Hence the visible part of electromagnetic spectrum lies in between ultraviolet and infrared.
Ans.
Genetic engineering involves manipulation of genetic material organisms to develop organisms with desirable characteristics. Natural selection involves selection of traits that make organisms better adapted to their surrounding environment, without human interference.
Both of the mechanisms involve transmission of genetic information form one generation to another as manipulated genetic material of parent organism is transmitted to next generation.
Both genetic engineering and natural selection select the traits that are most organisms with most beneficial to their environment.
Genetic engineering is faster than the process of natural selection. Natural selection is natural process and it works over generations, while genetic engineering involves desired modification of traits.
Both genetic engineering and natural selection work on all organisms, including humans.
Natural selection involves selection of individuals with beneficial traits for survival, while other individuals with less useful characteristics are wiped out. Therefore, natural selection does not work on entire population.
Thus, the options 1), 3), and 4) are correct.
C. It produces ultraviolet radiation It protects us from the uv rays to an extent
