Some languages, such as Japanese, Chinese, and Korean, require more than 256 unique symbols. The use of two bytes, or 16 bits, for each symbol, however, permits the representation of up to 65,536 characters or ideographs. Such an arrangement is called a “double-byte character set” (DBCS); Unicode is the international standard for such a character set True False Bats while flying emit a set of short squeaks which are ultrasonic waves.

True False In cloning sperm is not used True False The most common defect-seen across most of the species that have been cloned so far- is a condition known as large-offspring syndrome. Those clones are born larger than normal and have trouble breathing in their first few weeks. Most of the surrogates that give birth to them experience prolonged pregnancies and sluggish, difficult labors, which may have something to do with their distended and enlarged placentas. True False Telomeres are bits of DNA that sit at the ends of chromosomes and serve as a biological clock chronicling a cell's age. In general, the shorter the telomeres, the older the cell. True False We have a whole pharmacy within us. We can create any drug inside us True False The tooth is the only part of the human body that can't repair itself.

(DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. Infection with one of these serotypes provides immunity to only that serotype for life, so persons living in a dengue-endemic area can have more than one dengue infection during their lifetime.

True (polyvinyl chloride is both the name of a binder and the name of a plastic into which it is made) False The first important plastic, celluloid, was discovered (c.1869) by the American inventor John W. Hyatt and manufactured by him in 1872; it is a mixture of cellulose nitrate, camphor, and alcohol and is thermoplastic. True False A series of eight consecutive bits is called a “byte”; the eight-bit byte permits 256 different “on-off” combinations. Each byte can thus represent one of up to 256 alphanumeric characters, and such an arrangement is called a “single-byte character set” (SBCS); the de facto standard for this representation is the extended ASCII character set. Some languages, such as Japanese, Chinese, and Korean, require more than 256 unique symbols. The use of two bytes, or 16 bits, for each symbol, however, permits the representation of up to 65,536 characters or ideographs. Such an arrangement is called a “double-byte character set” (DBCS); Unicode is the international standard for such a character set True False Bats while flying emit a set of short squeaks which are ultrasonic waves. These, after reflection from trees and buildings reach the ear of the bats and make them judge, by hearing the echo of the ultrasonic sound, the distance and direction of the obstacle in the air. True False Nails are connected with cartilages and blood vessels. While cutting, therefore, the nervous system is affected and we feel pain. True False Ozone is a molecule containing three oxygen atoms. It is blue in color and has a strong odor. Out of each 10 million air molecules, about 2 million are normal oxygen, but only 3 are ozone. The ozone layer absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of ultraviolet light called….. Which has been linked to many harmful effects, including various types of skin cancer, cataracts, and harm to some crops, certain materials, and some forms of marine life. UVA UVB UVC When you blush, the lining of your stomach also turns red True False The color blue has a calming effect.

True False Your brain is full of nerve cells, but it has no pain receptors. Doctors can operate on your brain while you're awake and you won't feel a thing. True False An antibiotic is a drug that kills or slows the growth of bacteria. They have no effect against viruses, fungi, or parasites. Antibiotics are one class of antimicrobials, a larger group which also includes anti-viral, anti-fungal, and anti-parasitic drugs. True False Gastroenteritis means inflammation of the stomach and small and large intestines. Viral gastroenteritis is an infection caused by a variety of viruses that results in vomiting or diarrhea. It is often called the "stomach flu," although it is not caused by the influenza viruses. True False Scientists are now discovering small flaws in the genomes of clone. The more scientists have learned about the inner workings of the procedure that created Dolly, the more they are amazed that she survived at all. Dolly, in fact, was the sole survivor of 277 cloning attempts. Clones, as the scientists who make them are fond of saying, are the exception rather than the rule. True False In cloning sperm is not used True False The most common defect-seen across most of the species that have been cloned so far- is a condition known as large-offspring syndrome. Those clones are born larger than normal and have trouble breathing in their first few weeks. Most of the surrogates that give birth to them experience prolonged pregnancies and sluggish, difficult labors, which may have something to do with their distended and enlarged placentas. True False Telomeres are bits of DNA that sit at the ends of chromosomes and serve as a biological clock chronicling a cell's age. In general, the shorter the telomeres, the older the cell. True False We have a whole pharmacy within us. We can create any drug inside us True False The tooth is the only part of the human body that can't repair itself. True False When you eat meat and drink milk in the same meal, your body does not absorb any of the milk's calcium. It is best to have 2 hours between the milk and meat intake. False True Every person has a unique tongue print. True False It is estimated that only 10 percent or less of an earthquake's total energy is ultimately radiated as seismic energy, while most of the earthquake's energy is used to power the earthquake fracture growth and is eventually converted into heat. True False Owls have eyeballs that are tubular in shape, because of this, they cannot move their eyes True False There are substitutes for human blood Yes No A polecat is not a cat. It is a nocturnal European weasel. True False Snakes are not immune to their own poison True False Blood centers often run short of type O and B blood. True False A woodpecker can peck twenty times a second. True False It may take longer than two days for a chick to break out of its shell. True False A chameleon's tongue is twice the length of its body. True False Fourteen tests, 11 of which are for infectious diseases, are performed on each unit of donated blood. True False Apheresis (ay-fur-ee-sis) is a special kind of blood donation that allows a donor to give specific blood components, such as platelets. True False Donated red blood cells must be used within 42 days of collection. Donated platelets must be used within five days of collection. Plasma can be frozen and used for up to a year. True False A pint is pound of blood etc True False Anyone who is in good health is at least 17 years old, and weighs at least 110 pounds may donate blood every 56 days. True False Blood of insects is Red Yellow Blue The bloodhound is the only animal whose evidence is admissible in an American court. True False Every 30 seconds a house fire doubles in size. True False The cigarette lighter was invented before the match. True False Bullet proof vests, fire escapes and windshield wipers are all invented by women. True False It is impossible to lick your elbow. True False Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (- a closely related set of viruses that can be differiented by the immune response they produce.) (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. Infection with one of these serotypes provides immunity to only that serotype for life, so persons living in a dengue-endemic area can have more than one dengue infection during their lifetime. Pakistan first reported an epidemic of dengue fever in 1994. True False Dengue fever occurs following the bite of an infected mosquito Aedes aegypti. Dengue fever is a severe, flu-like illness that affects infants, young children and adults, but seldom causes death. True False In 1939, Paul Müller discovered that DDT was a very effective insecticide. It quickly became the most widely-used pesticide in the world. However, in the 1960s, it was discovered that DDT was preventing many fish-eating birds from reproducing which was a huge threat to biodiversity. True False Penicillin is a bactericide True False A tornado is a violently rotating column of air which is in contact with both a cumulonimbus (or, in rare cases, cumulus) cloud base and the surface of the earth. Tornadoes can come in many shapes, but are typically in the form of a visible condensation funnel, with the narrow end touching the earth. Often, a cloud of debris encircles the lower portion of the funnel. True False Tornadoes are not found on Asia Africa Antarctica America Vortex term is associated with Cyclone Tornado Tsunami None A waterspout is merely a tornado over water. True False Tornadoes normally rotate in a cyclonic direction (counterclockwise in the northern hemisphere). Large-scale storms always rotate cyclonically because of the Coriolis force. True False The only 2 animals that can see behind itself without turning it's head are the rabbit and the parrot. True False A zebra is White with black stripes. Black with white strips Both none Electricity doesn't move through a wire but through a field around the wire.

Aryabhatta was the scientist who invented the digit zero. True False Dolphins sleep in a semi-alert state by resting one side of their brain at a time. Dolphins sleep with one eye open True False Bats can also find food up to 18 ft. away and get information about the type of insect using their sense of echolocation. True False Man is the only animal who'll eat with an enemy True False A chimpanzee can learn to recognize itself in a mirror, but monkeys can't True False Birds don't sweat True False Antarctica is DRIEST continent.
