What is the use of the sphygmomanometer?
A sphygmomanometer is the gauge used to measure blood pressure. The sphygmomanometer reads both systolic and diastolic pressure. A doctor takes these measurements by putting on the cuff and pumping it up, which cuts off the blood flow.

Why does the moon control the tides?
The tides are due to the gravitational pull of the Moon and the Sun on the Earth. Because the gravitational force decreases as the distance squared, the part of the Earth that is closer to the Moon or the Sun is pulled a little extra and a bulge is created.

Which planet has highest temperature?
Venus, the second closest plant to the Sun, has the highest average temperatures of any planet in our Solar System, regularly reaching temperatures over 460°C. Venus is so hot because of its proximity to the Sun and its thick atmosphere.

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.

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.

What kind of animals live in the desert?
There are coyotes, foxes, peccaries, tarantulas, scorpions, ring tailed cats, antelope, skunks, mule deer, boars, and in some places, lions and elephants. There is an abundance of small animals that support the deserts population of hawks, falcons, owls, roadrunners, buzzards, and eagles.

What animals eat spiders?
Because they are small, spiders have many enemies. Larger animals, such as birds, toads, lizards and monkeys, hunt them. But they are also used as food by many smaller creatures. Ticks will attach themselves to a spider and eat away at it for a long time while the spider goes about its business.

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).
