Corona is a virus and is very dangerous. EXPLANATION:The ONES suffering from corona have to be ISOLATED in -2 degree. It's very dangerous for MANKIND.

because the FIRST STABLE product FORMED in the kreb's CYCLE contain THREE carbonsExplanation:

so sorry I don't KNOW the answer.but please adit your QUESTION it is difficult to UNDERSTAND what you try to ASK.

hello friend!FERTILIZERS are composed of nitrogen, phosphorus, and potassium COMPOUNDS. They also contain trace elements that improve the growth of plants. The primary COMPONENTS in fertilizers are nutrients which are vital for plant growth. Plants use nitrogen in the synthesis of proteins, nucleic acids, and hormones.I hope you have a great day ahead I hope this helps you!If you are satisfied with my answer then PLEASE give me a thanks and mark my answer as the BRAINLIEST!

It is a chemical reaction between substance and oxygen in the FORM of flame EXPLANATION:~follow me please and Mark as brainliest I'm Tannu RANA ♥

cal reaction is in equilibrium when the concentrations of reactants and PRODUCTS are constant - their ratio does not vary. Another way of DEFINING equilibrium is to SAY that a SYSTEM is in equilibrium when the forward and REVERSE reactions occur at equal rates.⚠

To calculate the ENERGY required to RAISE the temperature of a known mass of a substance, you use the equation E = m × c × θ, where E is the energy TRANSFERRED in joules, m is the mass of the substances in kg, c is the specific HEAT capacity in J/kg degrees C and θ is the temperature CHANGE in degrees CExplanation:

e non-LIVING when they are OUTSIDE the any living organism but when they are come inside any living organism they get active and start to reproduce and get spread all over the BODY

both r dangerous........How do I PROTECT myself?The best thing is regular and THOROUGH hand washing, preferably with soap and water.Coronavirus spreads when an infected person coughs small DROPLETS - packed with the virus - into the AIR. These can be breathed in, or cause an infection if you touch a surface they have landed on then your eyes, nose or mouth.So, coughing and sneezing into tissues, not touching your face with unwashed hands, and avoiding close contact with infected PEOPLE are important for limiting the spread.Face masks do not provide effective protection, according to medical experts.

Shortage of water.Shortage of food.Shortage of breath (as plants DONOT get ENOUGH water)They WILLNOT survive.

scientists are searching for DECADES the answer of this QUESTION and i GUESS it is an interesting question... if we add hundred PERCENT of cerebral capacity then we must have to go to Agra at the mental hospital thank you hope you like it please make me as brain there and and and anddon't forget to FOLLOW me❤❤

As water vapor rises higher in the atmosphere, it begins to cool back down. When it is cool enough, the water vapor CONDENSES and returns to liquid water. These water droplets EVENTUALLY gather to form clouds and PRECIPITATION. The fresh-water vapor then condenses into clouds, MANY of which drift over land.

1. Adaptation is a change in both physical and chemical COMPOSITION of an organism brought about by habitat CHANGES, while ACCLIMATION is a physical reaction made in order to adjust to said changes. 2. Adaptation is permanent, while acclimation is TEMPORARY.

The INSTRUMENT was FITTED with CONCAVE MIRROR.

Ans1 Specific features of the liquid-in-glass clinical thermometer are: A 'kink' in the glass tube which breaks the mercury as it contracts, storing the highest temperature reading. The glass tube is shaped like a lens to magnify the thin mercury thread. Shaking the thermometer resets the mercury back into the bulb.Explanation:ans2-Pizza boy(delivery man ) keep the Pizzas in a  box which is made up of hard material from outside an inside it is made of thermocol (polystrene (C8H8)n).Thermocol is a poor conductor of heat so, it niether conducts heat energy to the surroundings nor it absorbs heat energy so the pizza kept in the box made up of thermocol will remain hot for a longer time. The box can be made up of any other material also from inside which is a poor conductor of heat.ans3-In winter black clothes will make him more comfort because black colour will observe heat faster than white clothes. During winter it will be cold everywhere if we wear black it will be useful to keep our body warm.b) In summer white clothes will make him comfort because during summer it is very hot in our surrounding white colour will observe the heat slowly than black colour.ans4-frying pan is ade up of metal because aluminum or stainless steel heats faster and better. Handle is made of plastic or wood because they won't absorb heatans5-Air and silica glass are both extremely poor conductors of heat, and thus GREAT insulators. That's why you can touch them after coming out of a super-hot oven. On the Space Shuttle, they protected the aluminum hull from the heat of reentry.ans7-In addition to Dennis' answer, air is a poor conductor because its molecules are not in continuous contact with one another unlike a solid. Heat by conduction passes more quickly in a solid because the molecules' vibrations immediately affect their neighbours.ans8-Heat can flow from one place to another, like all kinds of energy. ... Heat can flow in a vacuum by process called radiation, where heat transfers through electromagnetic waves. Heat flows in solids by conduction, where two objects in contact with each other transfer heat between them.ans9-Digital thermometers provide faster resultsMercury thermometers are designed utilizing the idea that mercury expands with heat. ... Mercury is used because it remains liquid throughout various temperatures as opposed to water, which freezes in colder temperatures. ans10-HEATER is placed near the floor because hot air RISES up and the room will be heatness will spread even. The density of air depends upon the temperature. ... So it is placed near the ceiling because the cool ( high density ) air tends to SETTLE downwards.ans11-Thermal infrared cameras can see people in complete darkness because warm objects (actually, anything hotter than absolute zero) emit blackbody radiation. Infra-red is the shortest wavelength component of that radiation, and so gives the best resolution.ans12-This property is used in SOLAR cooker where sunlight beats on the device and due to its black color more heat is absorbed. Solar cooker are painted black to maximize the absorption of heat from the sun. Explanation: Solar cooker is a device that uses the solar energy to cook the food present inside it.ans13-The plastic used to make uniform of fireman is Melamine because,Melamine is a fire retardant plastic, which resist the spread of fire. It is used in the uniform of fireman for the protection of human body form heat hazards.It is also use in airplanes, buses etc. to prevent the spread of fireans14-IThermocol box is made up of polystyrene ,a kind of synthetic plastic which is a bad conductor of heat. Hence prevents the flow of heat from surrounding air entering into box. As it acts as insulator for transmission of heat, Ice kept in thermocol does not melt fast and retains coolness for longer time.Answer:15 Radiation is the fastest mode of transfer of heat, because radiation travels at the speed of light, which is very quick. The slowest mode of transfer of heat is conduction because it takes place from particle to particle.Aug 20, 2013

1. COAL And Oil are the natural gases2. Coal and oil release natural gas when they are burned3. Sun generates its ENERGY by the PROCESS of NUCLEAR fusionExplanation:

a) Ozone layer is GETTING DEPLETED because of excess Clouroflourocarbon, carbon monoxide and human activities.b) The TWO forms of oxygen found in atmosphere are elemental oxygen and ozone.Please...... MARK me as brainliest.
