Which gas is known as laughing gas?
Laughing gas is nitrous oxide, N2O (more properly called dinitrogen oxide). It is a colorless gas with a sweet odor and taste. Inhalation leads to disorientation, euphoria, numbness, loss of motor coordination, dizziness, and ultimately a loss of consciousness.

Which bird has the largest eyes?
The eye of a bird is larger compared to the size of the animal than for any other group of animals, although much of it is concealed in its skull. The Ostrich has the largest eye of any land vertebrate, with an axial length of 50 mm (2 in), twice that of the human eye.

What oath does a doctor take?
Hippocratic Oath: Modern Version. I swear to fulfill, to the best of my ability and judgment, this covenant: I will respect the hard-won scientific gains of those physicians in whose steps I walk, and gladly share such knowledge as is mine with those who are to follow.

What is the hormone that wakes you up?
To prepare for the stress of waking, your body releases a cocktail of stress hormones, like cortisol. Gradually, your sleep becomes lighter and lighter. And that's why you wake up before your alarm. Your body hates your alarm clock.

What were the first forms of life on Earth?
For the next 1.3 billion years (3.8 to 2.5 billion years ago), the Archean Period, first life began to appear and the world's landmasses began to form. Earth's initial life forms were bacteria, which could survive in the highly toxic atmosphere that existed during this time.

What breeds of dogs can see in color?
Neitz confirmed that dogs actually do see color, but many fewer colors than normal humans do. Instead of seeing the rainbow as violet, blue, blue-green, green, yellow, orange and red, dogs would see it as dark blue, light blue, gray, light yellow, darker yellow (sort of brown), and very dark gray.

What time period are we in?
In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age and shorter than a period. We are currently living in the Holocene Epoch of the Quaternary Period. Rock layers deposited during an epoch are called a series.

What is an upside down rainbow called?
An upside-down rainbow is an unusual phenomenon caused by sunlight shining through a thin, visible screen of tiny ice crystals high in the sky. Interestingly enough, it has nothing to do with rain. Some people refer to this as a 'smile rainbow'.

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.

How high is the top of the atmosphere?
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).

Why is it called the Continental Divide?
The Continental Divide, also called the Great Divide, is a natural boundary line separating waters that flow into the Atlantic Ocean or Gulf of Mexico from those that flow into the Pacific Ocean. It runs north-south from Alaska to northwestern South America.

Do fish sleep at night?
Yes, I would say that fish do sleep. Some fish actually lie on the bottom at night. Some of them even produce a gooey covering as a protection against other fish who might be looking for an easy meal. In the dark many fish have a lower rate of metabolism (their body machinery slows down), and that is much like sleep.

How many active volcanoes are there in the world?
There are about 1500 potentially active volcanoes worldwide, aside from the continuous belt of volcanoes on the ocean floor. About 500 of these have erupted in historical time. Many of these are located along the Pacific Rim in what is known as the 'Ring of Fire.'

Is a mushroom a vegetable?
A mushroom is neither a fruit nor a vegetable; technically mushrooms aren't even plants. They are a special type of fungus—a notion that puts some people off. If you don't mind the fungus part, though, mushrooms are a great addition to a healthy diet—not to mention totally delicious.

What part of the body never stops 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.

Why are your lips red?
Your lips' red or pink pigment comes from underlying blood vessels -- red-colored, blood-filled capillaries are close to the thin skin on your lips. The transition of the reddish-pink outline of your lips to the rest of the skin is called the vermillion border, and it's found only in humans

What percentage of your weight is muscle?
Exercise is very important in maintaining a healthy body and the muscle mass % is a useful indicator to control it. The normal muscle mass percentage on the body weight lies between 38% and 54% for men and between 28% and 39% for women depending on age and physical activity level.

Why do cats eyes glow at night?
Cats, dogs, and many nocturnal creatures appear to have glowing eyes because the back of their eyeballs include a special reflective layer called the tapetum lucidum. This helps animals (cats in this case) see better in low light by working like a mirror on the retina to reflect the light back through the eyes,
