Independent variable: ultra violet radiation in gametic mutation, the organism which contains the mutation may not be affected, but it may or will be passed to its offspring, where the mutation might be, or can be expressed 3 understanding uv radiation essay understanding uv. Read this essay on uv light effect and repair lab report come browse our large digital warehouse of free sample essays uv radiation is typically placed into one of three categories uv-a radiation is the longest wavelength and has the least damaging effect into an organism this lab is to transform the bacteria ecoli with the gfp. Ultraviolet radiation is basically a form of radiant energy that comes from the sun the various forms of energy, or radiation are classified according to wavelength, measured in nanometers (one nanometer is a millionth of a millimeter)(ozone depletion page 2) the shorter the wavelength, the more energetic the radiation.

One example of this is the mutagenic radiation which is a physical mutagen that includes non- ionizing radiation such as microwaves, light, radio waves and uv and ionizing radiation such as x-rays, gamma rays, beta and alpha particles and neutrons (campbell and reece, 2008. Ozone is acting as a protective radiation shield or natural sun for all living organisms on the earth it strongly absorbs ultraviolet radiations from the sun in the region 220-330 nm and thereby protects the life on earth from severe radiation damage, such as dna mutation and skin cancer. This free medicine essay on prevention of uv radiation-induced skin is perfect for medicine students to use as an example.

A close look at the evolution of life shows that initially the atmosphere was devoid of oxygen but photosynthesis activities of blue green algae another anaerobic unicellular organism helped in building up oxygen level in atmosphere, which in turn helped in the formation of ozone layer in stratosphere and the deadly ultraviolet radiation of the sun was detained in the upper atmosphere. Effects on the human body the effects of ultraviolet radiation on the human body can vary depending on the amount of exposure according to the nasa earth observatory, uv-a rays have beneficial effects on human skin by triggering essential vitamin d secretions for the body. Ultraviolet b radiation, harmful to living organisms, represents a small portion of the spectrum, from 290 to 320 nanometer wavelengths (illustration by robert simmon) dna readily absorbs uv-b radiation, which commonly changes the shape of the molecule in one of several ways. Professor robin williams and gigi williams of melbourne, australia - pioneers of invisible radiation photography downes, a, blunt, tp 1877 researches on the effect of light upon bacteria and other organisms.

Effects of radiation on living organisms 1 background the term radiation is elastic unfortunately it has come to mean “something terrible1” in ordinary conversation literally radiation means “anything. Ultraviolet radiation: ultraviolet radiation cover wavelength ranging from approximately 4x10^4m to 6x10^-10m the sun is an important source of ultraviolet radiation light, which is the main cause of sunburn. Abstract ultraviolet light can damage dna molecules if a cell's dna repair mechanisms can't keep up with the damage, mutations are the result. Protection against exposure to ultraviolet radiation preface this intersun report provides information to people on how to protect themselves from the potentially harmful effects of exposure to ultraviolet (uv) radiation following a detailed review of the scientific literature conducted.

Science folio essay sample air pollution is the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, death to humans, damage other living organisms such as food crops, or damage the natural environment. Uv is the most photochemically active type of radiation and is absorbed by many molecules in the skin and in the eye exposure to light is measured as the energy of the radiation that is received per unit area. Essay on the process of adaptive radiation and link it to evolution - charles darwin, the father of evolution theories, stated that the intelligence or the strength of specie does not guarantee its survival and the continuation of its genetic line.

Generally, the uv radiation studies found that the further away from the equator a population is found, the lighter the skin, due to the lower levels of radiation [1-3] the studies examining genes found multiple genes that are involved in the differences in skin color. The effects of radiation radiation is the emission of electromagnetic energy that is given off in the form of high speed particles that cause ionization during ionization radiation hits and knocks electrons from an atom creating charged ions. Ultra-violet radiation has a suppressive effect and, at the same time, an activating effect therefore, a modulating effect is the out come from uv radiation for example, uv light is used in aiding successful organ transplantation. Both nitrogen and oxygen are almost transparent to the incoming radiation from the sun and also to the outgoing radiation from the earth and the atmosphere, but it does absorb short wave ultraviolet and x -ray radiation at high level in the atmosphere.

  • Solar uv radiation penetrates to ecological significant depths in aquatic systems and can affect both marine and freshwater systems from major biomass producers (phytoplankton) to consumers ( eg , zooplankton, fish, etc ) higher in the food web.
  • All plants and animals use energy from sunlight ultraviolet exposure, or uv radiation, is electromagnetic light radiation with wavelengths shorter than visible light, so humans cannot register it in the color spectrum.
  • Useful for disinfection and sterilisation – uv has positive applications in the fields of disinfection and sterilisation uv can effectively ‘kill’ (deactivate or destroy) microorganisms such as viruses and bacteria, for example, when hanging cloth nappies, underwear and tea-towels outside on the clothesline.

These spores are extraordinarily resistant to environmental stresses such as heat, ultraviolet radiation, gamma radiation, chemical disinfectants, and desiccation and can remain dormant for extremely long periods of time. Essay uv radiation induces a mutation if uv radiation induced a mutation in the dna of serratia marcescens and prevented the production of the red pigment called prodigiosin hypothesis: maybe the disappearance of red color in serratia marcescens is caused by the uv light which induces mutations in its dna and is known as a common mutagen. Uv radiation is capable of destroying most microbes that are present in air and on surfaces it has a short wavelength (between 220-280nm) and functions optimally at approximately 265nm the use of uv radiation causes the formation of thymine dimers. Read this article to learn about the effects of radiation on plants and animals effects of radiation on plants: according to the health physics society radiations have a positive effect on plant growth at lower radiation levels and harmful effects at high levels.
