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.

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 colors make you feel hungry?
It's one of the reasons why most fast food colors are orange and red and why the color yellow makes babies cry. We know through many scientific tests that red causes us to feel hungry and we know that yellow makes babies think they are in the sunlight so thy cry to tell their moms that they don't like it.

What causes your heart to beat?
The electrical system of your heart is the power source that makes this possible. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.

Why are snakes on the medical symbol?
The ribbons were later replaced by serpents, as one story tells that Hermes used the stick to separate two fighting snakes , who then coiled around his staff and remained there in balanced harmony. Another, earlier depiction of the medical symbol is the staff of Asclepius, thought it has no wings and only one snake.

What connects the Pacific Ocean and the Atlantic Ocean?
The Panama Canal is not the only water line connecting the Atlantic and Pacific Oceans. There's a place in Wyoming—deep in the Teton Wilderness Area of the Bridger-Teton National Forest—in which a creek splits in two. Like the canal, this creek connects the two oceans dividing North America in two parts.

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 long does a caterpillar stay in a cocoon?
The process from egg to butterfly is weather dependent and also depends on the regional climate. It can take about four weeks in the peak of the summer in warmer climates. The egg takes 5 to 10 days, the larva/caterpillar and pupa/chrysalis each take about 10 to 14 days.

What causes the aurora?
When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights

What animal is called the ship of the desert?
Camels are the only animals that can carry heavy loads from place to place in the desert because they can go for long periods without eating or drinking water. A camel's hump doesn't carry water, as some believe. Instead the hump is filled with fat, which is a built-in food supply.

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.

Is there an aurora borealis at the South Pole?
This results in an oval ring around each magnetic pole where auroras occur. The north pole aurora is called the aurora borealis and the aurora at the south pole is called the aurora australis. Depending on the level of recent solar activity, there may or may not be visible auroral activity all the way around the ring.
