Do cats see color or just black and white?
Although it is commonly believed that dogs and cats see only in black and white, recent evidence suggests that animals may have some degree of useful color vision. The perception of color is determined by the presence of cone photoreceptors within the retina.

How many time zones are there?
Given a 24-hour day and 360 degrees of longitude around the Earth, it is obvious that the world's standard time zones have to be 15 degrees wide, on average. Some sources claim there are 24 standard time zones, while others say there are 25 time zones.

Is the earth farther away from the sun in the winter?
Earth is closest to the sun every year in early January, when it's winter for the Northern Hemisphere. We're farthest away from the sun in early July, during our Northern Hemisphere summer. Earth is about 5 million kilometers – or 3 million miles – closer to the sun in early January than it will be in early July.

Do dogs have baby teeth like humans?
Like humans, dogs have two sets of teeth in their lives. The 28 baby teeth erupt through the gums between the third and sixth weeks of age. Puppies do not have to grind much food, so they do not have molars. Puppy teeth begin to shed and be replaced by permanent adult teeth at about four months of age.

Which color of light is higher in energy?
The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light.

How do you measure horsepower?
Horsepower (hp) is unit of measurement of power, the rate at which work is done. The most common conversion factor, especially for electrical power, is 1 hp = 746 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses.

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.

Which animal has the biggest brain in the world?
The average adult human brain weighs about 3 pounds – the same weight as the average brain of a dolphin (which is also a very intelligent animal). But there are animals with larger brains that are not considered to be as intelligent as a dolphin. For instance, a sperm whale has a brain that weighs about 17 pounds.

How many pairs of chromosomes are in a human body?
Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome.

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.

How high can a tsunami get?
Most tsunamis cause the sea to rise no more than 10 feet (3 meters). The Indian Ocean tsunami caused waves as high as 30 feet (9 meters) in some places, according to news reports. In other places witnesses described a rapid surging of the ocean. Flooding can extend inland by a thousand feet (300 meters) or more.

Do all bears hibernate in the winter?
It is a common misconception that bears hibernate during the winter. While bears tend to slow down during the winter, they are not true hibernators. Black bears, Grizzly bears and Brown bears do go into a deep sleep during the winter months, known as torpor. Hibernation is when animals “sleep” through the winter.

Do cashew nuts come from a fruit?
The top end of the cashew apple is attached to the stem that comes off the tree. The bottom end of the cashew apple attaches to the cashew nut, which is encased in a shell. In botanical terms, the cashew apple is an accessory fruit that grows on the cashew seed (which is the nut).

Which finger nail grows the fastest?
On average, fingernails grow about one tenth of an inch in a month. The fastest growing nail is the one on your middle finger. The slowest growing nail is your thumb nail. Freshly cut nails grow faster than nails that aren't cut regularly.

What does the mega mouth shark eat?
Known prey of the Megamouth Shark consists entirely of planktonic animals, including euphausiid shrimps, copepods, and the Pancake Jellyfish (Atolla vanhoeffeni). Yet most plankton is found near the surface, so it is something of a mystery how Megamouth manages to find enough to eat.
Know more about:
1- Plankton
2- Euphausiid Shrimp or Krill
3- Copepod
4- Atolla or Pancake Jellyfish

Why does Japan get so many earthquakes?
Why Japan has so Many Earthquakes. Japan is located along the Pacific “ring of fire”, on the edges of several continental and oceanic tectonic plates. This is an area of high seismic and volcanic activity from New Zealand, up through Japan, across to Alaska, and down the west coasts of North and South America.

1- Pacific Ring of Fire
2- Earthquake
3- Tectonic Plate
4- Oceanic Plate
5- Continental Plate

What percentage of the earth's water is drinkable?
Two percent of the water on earth is glacier ice at the North and South Poles. This ice is fresh water and could be melted; however, it is too far away from where people live to be usable. Less than 1% of all the water on earth is fresh water that we can actually use.

What is a black hole?
A black hole is an area in space where matter (what everything is made of) has collapsed in on itself.
A black hole has a strong gravitational pull that sucks in everything nearby – even light. Nothing can escape it.
Many galaxies have black holes in them. A black hole is large enough to pull objects near it, but not those far away.
Even supermassive black holes will not continue to grow forever. Just as the black hole was born, it will one day die. A black hole will slowly evaporate, releasing the energy it took back into space.
