⁉️ How fast does the human heart beat per minute?
✅ For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the person's physical condition. For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm. Athletes and those in excellent physical condition can have resting heat rate of 40 bpm.

⁉️ Is the North Star the brightest star in the sky?
✅ Polaris ( Ursae Minoris, Alpha Ursae Minoris, commonly North Star, Northern Star or Pole Star, also Lodestar, sometimes Guiding star) is the brightest star in the constellation Ursa Minor. It is very close to the north celestial pole, making it the current northern pole star.

⁉️ Which sea on the Earth has no beaches?
✅ The Sargasso Sea, The Sea Without A Shore. The Sargasso Sea is located in the middle of the Atlantic Ocean, just a little north of the equator. The water in the Sargasso Sea is one of the clearest in the ocean, with underwater visibility of up to and incredible 200 feet.

⁉️ What is the percentage of nitrogen gas in the air?
✅ It is primarily composed of nitrogen (78%) and oxygen (21%) with only small concentrations of other trace gases. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth's weather takes place.

⁉️ How many bones are in the human hand?
✅ The human hand has 27 bones, not including the sesamoid bone, the number of which varies between people. 14 of which are the phalanges (proximal, intermediate and distal) of the fingers. The metacarpals are the bones that connects the fingers and the wrist.

⁉️ What organ produces adrenaline?
✅ Epinephrine and norepinephrine are two separate but related hormones secreted by the medulla of the adrenal glands. They are also produced at the ends of sympathetic nerve fibres, where they serve as chemical mediators for conveying the nerve impulses to effector organs.

⁉️ What mineral is the hardest?
✅ As it says in Mohs scale, the diamond is always at the most top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and for last and the hardest, diamond.

⁉️ When does the brain stop growing?
✅ We used to think that the brain was fully developed by very early teenagerhood and we now realise that the brain doesn't stop developing until mid-20s or even early 30s. There's a lot more information and evidence to suggest that actually brain development in various forms goes on throughout the life span.

⁉️ 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 animal represents Scotland?
✅ The unicorn is the national animal of Scotland. The Royal Coat of Arms of Scotland, used prior to 1603 by the Kings of Scotland was supported by two unicorns and the current royal coat of arms of the United Kingdom is supported by a unicorn for Scotland along with a lion for England.

⁉️ Are clouds made up of liquid or gas?
✅ Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water. Water existing as a gas is called water vapor.

⁉️ When do ears and nose stop growing?
✅ Bones, stop growing after puberty and muscle and fat cells also stop dividing. But cartilage - that's the plastic-like stuff in ears and noses - cartilage continues to grow until the day you die. Not only does cartilage grow, but the earlobes elongate from gravity. And that makes ears look even larger.

⁉️ What is the instrument used to measure earthquakes?
✅ Seismometers are instruments that measure motions of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.

⁉️ Which river rises in the Black Forest and flows into the Black Sea?
✅ The river rises in the Black Forest Mountains of Germany and flows eastward into the Black Sea. The Danube River is an important international waterway, flowing through or forming a part of the borders of ten countries and through major cities such as Vienna, Bratislava, Budapest, and Belgrade.

⁉️ 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.
