rsity GENERALLY refers to the variety and variability of life on Earth. According to the United Nations Environment Programme (UNEP), biodiversity typically measures variation at the genetic, species, and ecosystem level.[1] Terrestrial biodiversity tends to be greater near the equator,[2] which seems to be the result of the warm climate and high primary productivity.[3] Biodiversity is not distributed evenly on Earth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[4] Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity.[5] Biodiversity generally tends to cluster in hotspots,[6] and has been increasing through time,[7][8] but will be likely to slow in the future.[9]Rapid environmental changes typically cause mass extinctions.[10][11][12] More than 99.9 percent of all species that ever lived on Earth, amounting to over five billion species,[13] are estimated to be extinct.[14][15] Estimates on the number of Earth's current species range from 10 million to 14 million,[16] of which about 1.2 million have been documented and over 86 percent have not yet been described.[17] More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described.[18] The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes.[19] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).[20] In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth.[21]The age of the Earth is about 4.54 billion years.[22][23][24] The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago,[25][26][27] during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia.[28][29][30] Other early PHYSICAL evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland.[31] More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia.[32][33] According to one of the researchers, "If life arose relatively quickly on Earth .. then it could be common in the universe."[32]Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion—a period during which the majority of multicellular phyla first appeared.[34] The next 400 million years included REPEATED, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life.[35] The Permian–Triassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years.[36] The most recent, the Cretaceous–Paleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.[37]

re two basic approaches towards conservation of bio diversity:In situ conservationEx situ conservationI. In situ conservation:a)Biosphere reserves: Out of 425 biosphere reserves in the world, 14 are in INDIA. Hot spots are the areas / regions of HIGH endemism and very high levels of species richness. There are 34 hot spots in the world, of which three are in India; namely Western Ghats and Sri Lanka, Indo-Burma and Himalaya.b) National parks and wildlife sanctuaries: India has 90 nationals parks and 448 wildlife sanctuaries.Sacred groves: These are forest patches which were venerated and given total protection. It includes a number of rare, endangered and endemic species. Ex. Western Ghats, Khasi and Jaintia Hills in MeghalayaII. Ex situ conservation: India has 35 botanical gardens and 275 zoological parks. By USING Cryopreservation (-196o C) technique, sperms, eggs, animal cells, tissues and embryos can be stored for long period. Plants are propagated by using tissue culture methods called micropropagation.

effect on using plastic In our daily life Plastic are made by combining many harmful non bio degraded things. By keeping eat able things can lead to stomach cancer, DIARRHEA and many other harmful effect on both our body and environment . People should avoid the use of plastic but according to a report of 2014 still 64 percent of people in India use plastic in their everyday life. It is not eco friendly and can lead to LAND pollution on HIGH bases. Some people burn them in fire which lead to air pollution as when we burn plastic it release many harmful GAMES such as sulfur dioxide and Sulphur trioxide Hope this WOULD help you please mark it as brainest ans

are the natural things of our mother nature..it's helps us in so many ways..first of all it gives us fruits to eat .timber, if there will no trees or FORESTS there will be no rain,it gives shelter to the wild animals in the forests It FORMS a HIDING PLACE for the animals to HIDE from their predators..it gives us paper,wood and many more things..and the most useful thing is that it gives us oxygen..

to understand that the farmer applies fertilizer so that the plant would take it up and use it for growth. The fact that some of the fertilizer is polluting water means that it is not being taken up by the plant. In addition to being an environmental problem, it ALSO a waste of money for the farmer. The solution is to get the plant to use the fertilizer that is applied.The key is to ensure that we have a good growing conditions so that the crop can take up and make use of the applied nutrients. It means that we must have a productive crop variety suited to that area, planting must be properly done, pests, weeds and diseases must be controlled, in fact, all operations must be done properly. One important aspect of proper conditions is balanced nutrition. There must be an adequate supply of all of the other nutrients if the crop is to make use of the applied nitrogen and phosphorus.With nitrogen, it is critical to APPLY no more than is needed; any excess is certain to contribute to some FORM of pollution. Soil testing has not been sufficiently reliable to predict nitrogen needs, THEREFORE the crop requirements determined by local testing are also used.Timing of application of nitrogen is also important. Because it does not remain in the soil for very long, it is usually better to apply small, regular doses. It is best to time the APPLICATIONS to coincide with the periods when the crop needs it the most. This is where fertilizers have a big advantage over manure. It is not possible to control the release of nitrogen from manure. It may occur at a time when the crop does not need nitrogen allowing it to be easily leached out of the soil.There are a few chemicals which can modify the rate at which nitrogen reacts in the soil and reduce the chance of pollution. Urease inhibitors work by slowing down the rate at which urea is converted into ammonium nitrogen. Nitrification inhibitors reduce the rate at which ammonium nitrogen is converted into nitrates. The idea is to try to produce nitrate in the soil at the same rate at which the crop is using it so that there will be no excess that can be leached.Slow release fertilizers use physical coatings on the fertilizer granules to control the release of nutrients. Again, the idea is to match the release of nutrients with the rate of uptake by the crop.Erosion control measures can dramatically reduce phosphorus pollution. Again, balanced nutrition is a key element in that it promotes the rapid growth of plants whose leaves and residue protect the soil from direct rainfall. Reduced tillage and physical conservation measures have done a lot to protect surface water from the effects of phosphates transported with eroded soil.

bai, the Rani of JHANSI (19 November 1828 – 17/18 June 1858) was an Indian queen and warrior. She was one of the leaders of the Indian REBELLION of 1857 and became for Indian nationalists a symbol of resistance to the rule of the British East India Company in India. Manikarnika was born into a Maratha family at Varanasi. Manikarnika was one of the great freedom fighter in India. She was married to Raja Gangadhar RAO, the Maharaja of Jhansi in 1842 and became the Rani of Jhansi. After her marriage Manikarnika became Lakshmibai, so named in honour of the goddess Lakshmi. In 1851, Rani Lakshmibai had a son, Damodar Rao. He died at the age of about four months. On the day before the raja’s death in November 1853, he adopted a son. After the death of her husband the head of the British GOVERNMENT of India, Lord Dalhousie, refused to allow her adopted son to become raja and Jhansi was then ruled by the British. She was fighting against British for Jhansi. She always use or carry her weapons with her. According to tradition with Damodar Rao on her back she jumped on her horse Badal from the fort. They survived but the horse died. In the battle of Kotah ki Serai in which the British forces commanded by Sir HUGH Rose conquered Gwalior, fought on 17 and 18 June 1858, she died

O₂ is a greenhouse gas hence it can trap the HEAT of sun's ray.since the level of CO₂ in the past were low so the climate was cooler in the past. Now since the CO₂ levels are very high so it TRAPS more heat thus raising the TEMPERATURE of ATMOSPHERE more and more. This causes the melting of ICE cores thus increasing the sea levels.

of Pollution:Greenhouse gases, LIKE fossil fuels released by vehicles and factories, and methane, released by livestock, contribute to air pollution and add to climate change by RAISING the earth's temperature. In a vicious circle, climate change then makes a certain type of air pollution worse. A reaction between combusting fossil fuel emissions and sunlight creates smog, a yellowish or blackish fog also known as "ground level ozone." Climate change also creates more allergenic air pollutants, such as mold caused by damp conditions and pollen caused by a longer pollen season and increased pollen production.Air pollution can have a serious heath impact on humans. If you are exposed to very high levels of air pollutants, you may experience irritation of the eyes, nose and throat, wheezing, coughing and breathing problems and have a GREATER risk of heart attacks. Air pollution can also exacerbate existing lung and heart conditions, like ASTHMA. Smog can irritate the eyes and throat and also damage the lungs. Children, senior citizens and people who work or exercise outside are at a greater risk. Those most at risk are people with asthma or allergies because pollutants can make their symptoms worse and trigger asthma attacks.Across the world, climate change leads to more drought, heat waves, rising sea levels, storms, warming oceans and rising sea levels, which affect animal species by destroying their natural habitats.

es reasons for why we should conserve and manage the resources:*FIRST and foremost reason would be the "the resources present now very limited "and once these are lost is hard to get it back*We need to manage to otherwise our next generation won't be able to survive without these resources.*Over-exploitation of the resources would put a HUGE full STOP in the field of research and educational system.*Improper management can lead to DRASTIC increase in pollution which will further lead to different kinds of diseases.*Managing these can lead equal benefits to all the organisms on this planet.*If the resources aren't managed properly then there's no doubt that the planet earth would come to an soon.

nufacturing PROCESS :- 1. Firstly wool is removed from the sheep through a process called shearing.2. Then it is washed to remove the dust, dirt and GREASE through a process called scouring.3. The wool is separated based on the overall quality through a process called grading and is also separated based on which part of the body it is from through a process called sorting.4. The wool is then dyed into DIFFERENT colors.5. At last, it is spun into yarn and then it is either woven or knitted.Silk manufacturing process :-1. The eggs of silkworm moth are incubated until they hatch into a larvae.2. The larvae are fed on mulberry leaves for about SIX weeks.3. The silkworms spin the cocoon in about eight days.4. The cocoons are boiled to kill the insects inside them. The FILAMENTS are obtained from the cocoons by a process called reeling.5. The silk fibres are then spun into silk thread known as raw silk and it is used for weaving clothes as well as it can be dyed into different colors.Read more on Brainly.in - brainly.in/question/160592#readmore

oductive cloning, researchers remove a mature SOMATIC cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.Cloning is the process of producing genetically identical individuals of an ORGANISM either naturally or artificially. In nature, many organisms produce clones through asexual reproduction. Cloning in biotechnology REFERS to the process of creating clones of organisms or copies of cells or DNA fragments (molecular cloning). Beyond BIOLOGY, the term refers to the production of multiple copies of digital media or software. The term clone, invented by J. B. S. Haldane, is DERIVED from the Ancient Greek word κλών klōn, "twig", referring to the process whereby a new plant can be created from a twig. In botany, the term lusus was traditionally used.[1] In horticulture, the spelling clon was used until the twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o".[2][3] Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.

s of crackers are burned throughout our country each year to celebrate the Diwali festival. Burning crackers is like a ritual on this festival. It is a part of the celebration. The markets are flooded with different KINDS of fire crackers during the Diwali season and people begin shopping for the same days before the festival.Children are especially excited about burning crackers. However, even the adults indulge in this activity WITHOUT giving it a thought that this act is CAUSING pollution which is extremely harmful for the ENVIRONMENT. Air pollution levels in our country are on an all time high during the Diwali festival. This has given RISE to numerous health problems.People, who suffer from asthma and other lung problems, particularly have a difficult time during Diwali. Their problem augments during this time and it becomes hard for them to breathe. The burning of crackers also causes noise pollution which is especially a problem for the elderly people and little kids. It is also scary for animals that look for places to hide themselves as we burn crackers to celebrate Diwali.We must all remember that Diwali is the festival of lights not fire crackers. We should refrain from burning crackers and celebrate Diwali in a better way.
