Provide 5 specific examples of chemical or physical mutagens or carcinogens, along with the type of mutation they cause. NCERT Solutions for Class 12 Physics in PDF form free download. Light of same wavelength is incident on three photo-sensitive surfaces A, B and C. The following observations are recorded. Lesser-known biological mutagens are transposons. This is the list of some of the important physics formulas that are used by all class students mostly to solve physics problems. (b) What will be its resistance when its length becomes 2 Lo? Reactive oxygen species, benzene, gum elastic and rubber products, sodium azide, aromatic amines, alkaloids, deaminating agents, and PAH (Polycyclic aromatic hydrocarbons) are other mutagens that make different mutations. The mutagens are genotoxic- harmful to our DNA in some ways; some directly affect the DNA some indirectly.

If the frequency of light incident on the cathode of a photo-cell is increased, how will the following be affected ? A wide variety of agents are categorized as carcinogens. To minimize the percentage error in the determination of unknown resistance of a conductor in meter bridge experiment, the balance point is adjusted near _______ of the wire. Physical carcinogens include ultraviolet rays from sunlight and ionizing radiation from X-rays and from radioactive materials in industry and in the general environment. X-rays/heat, innumerable, and toxoplasma are several non-specific mutagens. March 1, 2020 March 1, 2020 by rajathe.
