Answer: they use physical and behavorial characteristics that animals have such as their bone structure and eating habits. taxonomy classifies all the living things on earth into 3 domains 7 kingdoms etc and these classifications condense the specific characteristics that a organism or group of organisms have and places them into groups ( kingdoms, phyla, domains etc..) that only organisms with those characteristics have. taxonomy links establishes relationships between all living things on earth.
Answer: All micro-organisms are no food poisoning micro-organisms,but all food poisoning micro-organisms are a category of micro-organisms. Food poisoning micro-organisms are harmful for a person but all micro-organisms are not harmful for example lacto-bacallius is a micro-organisms which is present in curd(yogurt) causes no food-poisoning whereas The microorganism salmonella bacteria, causes an infectious illness and can be passed on to another person and causes food poisoning.
Answer: electromagnetic radiation allows me to listen to the radio; heat radiation makes me warm at the beach; sound radiation carries your speech to me; ionizing radiation allows the sterilization of hospital supplies.
Answer: UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.
Answer: Cancers are caused by uncontrolled growth of tissue. Most commonly caused by environmental chemicals. Or fine fibres such as Asbestos or very fine glass. Ionizing radiation can cause cancers IF the damage it does then goes on to produce an unwanted growth of tissue.
Answer: Transgenic organisms are good because they are engineered to have the characteristics of another organism for its benefit. This increases resistance to harm and other factors in such organisms. As for harmful reasons, I cannot think of any.
Answer: any substances that hampers survival of a living organism is anti-bio. it is only due to some accidents in history that we discovered some metabolic by products of certain microorganisms caused the death or inhibition of others, hence the term antibiotics..... you can check my articles in internal medicine in this site lowellmd202.blogspot.com
Answer: There is no average dose as exposure varies from place to place, but anyone working with radiation should consult their Local Rules for guidance, and wear a dosimeter.The IAEA recommended that the annual dose for workers be under 20mSv. (20 milli-sieverts, where 1 sievert (J/kg) is the radiation required to impart 1 joule of energy in 1 kg of matter.) UK and EU (According to Walter and Millers Textbook of Radiotherapy, and Sheffield Hallam University UK): The UK and the EU have very strict guidelines for staff that work with ionising radiation. These are the dose limits that have been set up to help protect staff from unheathy amounts of radiation.Whole Body Dose Limits Per Year:Radiation Workers ages 18 yrs and older = 50 mSv.Trainees aged 18 yrs and older = 1 mSvGeneral public (frequent exposure) = 1 mSvGeneral public (infrequent exposure) = 5 mSv
