⁉️ How many teeth does an elephant have?
✅ Elephants usually have 26 teeth: the incisors, known as the tusks, 12 deciduous premolars, and 12 molars. Unlike most mammals, which grow baby teeth and then replace them with a single permanent set of adult teeth, elephants are polyphyodonts that have cycles of tooth rotation throughout their lives.

⁉️ Are doves and pigeons the same thing?
✅ Pigeons and doves constitute the bird family Columbidae, which includes about 310 species.
Pigeons and doves are stout-bodied birds with short necks, and short slender bills (and in some species, these bills feature fleshy ceres). They primarily feed on seeds, fruits, and plants. This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones.
In general, the terms "dove" and "pigeon" are used somewhat interchangeably. Pigeon is a French word that derives from the Latin pipio, for a "peeping" chick, while dove is a Germanic word that refers to the bird's diving flight.

⁉️ How much does the temperature change with altitude?
✅ Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 6.4C°/km (3.5F°/1,000 ft) of altitude above ground level. The measurable lapse rate is affected by the moisture content of the air (humidity).

⁉️ What does CT stand for in medical terms?
✅ CT, or CAT as they're pronounced, stands for "computerized axial tomography." In a CT scan, the patient lies on a table that slides into a scanning machine. Inside, an x-ray beam rotates around the body while detectors measure how much of the x-rays pass through the tissues and organs, indicating density.

⁉️ Is Greenland larger than Australia?
✅ The Mercator projection portrays Greenland as larger than Australia; in actuality, Australia is more than three and a half times larger than Greenland. As on all map projections, shapes or sizes are distortions of the true layout of the Earth's surface. The Mercator projection exaggerates areas far from the equator.

⁉️ How do snakes hear if they dont have ears?
✅ When people and most animals hear, sound waves strike the eardrum and go to the inner ear, which is sensitive to the sound waves or vibrations. Snakes do not have eardrums, but their skins, muscles, and bones carry the sound waves to the inner ears.

⁉️ Why is the wedding ring worn on the ring finger?
✅ According to a tradition believed to have been derived from the Romans, the wedding ring is worn on the left hand ring finger because there was thought to be a vein in the finger, referred to as the 'Vena Amoris' or the 'Vein of Love' said to be directly connected to the heart.

⁉️ What are the only two mammals that lay eggs?
✅ Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.

⁉️ How fast is terminal velocity of a bullet?
✅ Hatcher calculated that his .30-caliber rifle bullets reached terminal velocity—the speed at which air resistance balances the accelerating force of gravity—at 300 feet per second. You might die from a bullet moving at that speed, but it's unlikely.

⁉️ How does salt help preserve meat?
✅ Salting, especially of meat, is an ancient preservation technique. The salt draws out moisture and creates an environment inhospitable to bacteria. If salted in cold weather (so that the meat does not spoil while the salt has time to take effect), salted meat can last for years.

⁉️ What is the color of the black box in a commercial airplane?
✅ Black box or flight data recorder, mounted in the tail of an aircraft, is one of the most important gadgets that is used to reconstruct the events leading to a plane crash. The term "Black Box", however, is a misnomer as its colour is orange. This is done for easier location after a crash.

⁉️ Can graphite conduct electricity?
✅ Graphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

⁉️ Why do people throw rice at weddings?
✅ Throwing rice at a newly married couple has been a tradition for thousands of years, possibly going back as far as the ancient Assyrians and Egyptians. The idea is to give the newlyweds good luck, fertility, and abundance using this symbol of a good crop.

⁉️ Which country is known as the land of the midnight sun?
✅ Canada (Yukon, Northwest Territories, and Nunavut), Greenland, Iceland, Finland, Norway, Russia, Sweden, and the United States (Alaska). A quarter of Finland's territory lies north of the Arctic Circle and at the country's northernmost point the sun does not set at all for 60 days during summer.
