Why is the left lung smaller than the right lung?
The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the body. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex of the heart. Each lung consists of several distinct lobes.

What do you call the space between your nose and upper lip?
For humans and most primates, the philtrum survives only as a vestigial medial depression between the nose and upper lip. The human philtrum, bordered by ridges, also is known as the infranasal depression, but has no apparent function.

Why are the atomic masses listed on the periodic table not whole numbers?
The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. Being an average it would be most unlikely to be a whole number. The mass of an individual atom in atomic mass units is the mass relative to carbon-12.

Where does the black rose grow?
Called the Turkish Halfeti Rose, they only grow in exceptionally small numbers in the village of Halfeti, Turkey. They won't flourish anywhere else in the entire world because it's the river Euphrates that provides the ideal soil and growing conditions for the rose.

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).

How much does a tongue of a blue whale weigh?
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant.

What percentage of the world's population has green eyes?
Green eye color is often confused with hazel eye color, yet is entirely separate and distinct. Green eye color is the rarest color found around the world, and it is estimated that only around 2% of the world's population has green colored eyes.

What were the wisdom teeth used for?
Anthropologists believe wisdom teeth, or the third set of molars, were the evolutionary answer to our ancestor's early diet of coarse, rough food – like leaves, roots, nuts and meats – which required more chewing power and resulted in excessive wear of the teeth.

Is alcohol a vasodilator or vasoconstrictor?
At intoxicating levels, alcohol is a vasodilator (it causes blood vessels to relax and widen), but at even higher levels, it becomes a vasoconstrictor, shrinking the vessels and increasing blood pressure, exacerbating such conditions as migraine headaches and frostbite.

How high are the clouds?
Low-level clouds lie below 6,500 feet (2,000 meters). Meteorologists refer to them as stratus clouds. They're often dense, dark, and rainy (or snowy) though they can also be cottony white clumps interspersed with blue sky. The most dramatic types of clouds are cumulus and cumulonimbus, or thunderheads.

Why is a dog's nose wet?
Wet Nose, Cool Body. Moist noses are also one of the ways that canines can regulate body temperature and cool down. “Dogs don't have normal sweat glands, like people,” says Dr. King, “so they secrete sweat from the pads of their feet and their noses

Which species is most closely related to humans?
Humans, chimpanzees, gorillas, orangutans and their extinct ancestors form a family of organisms known as the Hominidae. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics.

How long is an exact year?
A solar year is the time it takes the Earth to complete its orbit around the Sun — about one year. But the actual time it takes for the Earth to travel around the Sun is in fact a little longer than that—about 365 ¼ days (365 days, 5 hours, 48 minutes, and 46 seconds, to be precise).

What makes the sky blue?
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
