DENEME SINAVI İsim Soyisim E-Posta Telefon Q. 1 The threatened extinction of the tiger in India, the perilous existence of the orangutan in Indonesia, the plight of the panda: these are wildlife emergencies with which we have become familiar. They are well-loved animals that no one wants to see disappear. But now scientists fear the real impact of declining wildlife could be closer to home, with the threat to creatures such as ladybirds posing the harshest danger to biodiversity. Climate change, declining numbers of animals, rising numbers of humans and the rapid rate of species extinction mean a growing number of scientists now declare us to be in the Anthropocene – the geological age of extinction when humans finally dominate the ecosystems. Last week a report from WWF, the Living Planet Index 2014, seemed to confirm that grim picture with statistics on the world's wildlife population which showed a dramatic reduction in numbers across countless species. The LPI showed the number of vertebrates had declined by 52% over four decades. Biodiversity loss has now reached "critical levels". Some populations of mammals, birds, reptiles, and amphibians have suffered even bigger losses, with freshwater species declining by 76% over the same period. But it's the creatures that provide the most "natural capital" or "ecosystem services" that are getting many scientists really worried. Three quarters of the world's food production is thought to depend on bees and other pollinators such as hoverflies. Never mind how cute a panda is or how stunning a tiger, it's worms that are grinding up our waste and taking it deep into the soil to turn into nutrients, bats that are catching mosquitoes and keeping malaria rates down. A study in North America has valued the loss of pest control from ongoing bat declines at more than $22bn in lost agricultural productivity. "It's the loss of the common species that will impact on people. Not so much the rarer creatures, because, by the very nature of their rarity, we're not reliant on them in such an obvious way," said Dr Nick Isaac, a macroecologist at the NERC Centre for Ecology and Hydrology in Oxfordshire. He says that recent work he and colleagues have been doing suggests that Britain's insects and other invertebrates are declining just as fast as vertebrates, with "serious consequences for humanity". "The really interesting thing about this work is that we are learning that it's not just about the numbers of species going extinct, but the actual numbers in a population; that's the beginning of a fundamental shift in our understanding," he says. The term ‘Anthropocene’ as referred to by scientists suggests, that:Deselect Answer the human species will die out soon. the human species will be the only surviving species. there are too many people on our planet. some animals are on the verge of extinction. the species rather than human will die out completely. Q. 2 According to the scientists, which of the following would be most disastrous for human existence?Deselect Answer Extinction of tigers Extinction of bees Extinction of pandas Extinction of orangutans Extinction of mosquitoes Q. 3 According to the LPI, over 40 years we have lost the majority of which species?Deselect Answer River and lake species Ocean species Vertebrae Mammals Birds Q. 4 Why are scientists more worried about the extinction of ladybirds rather than tigers?Deselect Answer Because their population is smaller than tigers. Because they catch insects. Because it will impact more on humans. Because they are dying more rapidly. Because they have closer physical relation with human.

Q. 6 SEIZURES IN ADULTSA seizure - also called a convulsion or fit - consists of involuntary contractions of many of the muscles in the body. The condition is due to disturbance in the electrical activity of the brain. Seizures usually result in loss or impairment of consciousness. The most common cause is epilepsy. Other causes include head injury, some brain damaging diseases, shortage of oxygen or glucose in the brain and the intake of certain poisons, including alcohol.Epileptic seizures result from recurrent, major disturbances of brain activity. These seizures can be sudden and dramatic. Just before a seizure, a casualty may have a brief warning period with, for example, a strange feeling or a special smell or taste. No matter what the cause of the seizure, care must always include maintaining an open, clear airway and a monitoring of the casualty’s vital signs: level of response, breathing and pulse. You will also need to protect the casualty from further harm during a seizure and arrange appropriate aftercare once they have recovered.1. Make space around the casualty; ask by passers to move away. Remove potentially dangerous items, such as hot drinks and sharp objects. Note the time the seizure started.2. Protect the casualty’s head from objects nearby; place soft padding such as rolledtowels underneath or around his neck, if possible. Loosen tight clothes around their neck, if necessary.3. When the convulsive movements have ceased, open the casualty’s airway and check breathing, place them in the recovery position.4. Monitor and record vital signs- level of response, breathing and pulse- until they recovers. Note the duration of the seizure. Where would you most likely find the above text?Deselect Answer In a newspaper In a journal In a first aid manual In a novel In a medical dictionary Q. 7 What is the best word to replace ‘involuntary’?Deselect Answer spontaneous instinctive automatic deliberately reflex Q. 8 What is the important action one needs to take when attending someone with a seizure?Deselect Answer Check if the casualty is conscious.
