Insecta refers to insects belonging to the Insecta class in the Hemiptera. Entomologists consider them true bugs. They have hair, gills and four legs. You may already know their looks, but did your know that they have other distinguishing characteristics?
Insects can be classified as invertebrates
Invertebrates refer to bugs as having both living and dead parts. Insects have segmented body parts and exoskeletons made from chitin. The main parts of their bodies are divided into the abdomen, head, and thorax. These body parts are used to extract nutrients. They use catabolic processes to digest their food. This breaks down complex macromolecules of sugar into simple sugars.
They have four legs
It is quite interesting to observe that some insects only have four legs and others have six. For example: butterflies have six legs, while locusts just have four. For jumping, insects use the front pairs of their legs.
They have gills
Most people are aware of the fact that some insects have "gills". They allow insects to breathe. They allow insects to see their environment. Most insects have many visual units. However, some species have complex eyes with hundreds of visual unit. For example, caterpillars have 12 sets eyes and 30,000 ommatidia.
They have hair
You need to know that bugs have hair. The most diverse animal group, insects, is the one that's worth studying. Insects play an important role in our environment and economy, and they're interesting to both humans and non-entomologists alike. These are some fun facts about insects: what do they eat? How do they jump?
They produce methane
Methane is known to be a greenhouse chemical. It is released in the atmosphere by bugs such as termites. About 5 percent of global methane emissions comes from these creatures, which produce methane through their guts. While methane can naturally occur in the air, methane from human activities is responsible for approximately 320 million tons each year. Fossil fuel industries (including the production of natural gas) are the largest sources of methane.
They have ommatidia
Insects can have compound eyes with seven to eleven different visual units. They are used for a wide variety of purposes. Some insects have more or less ommatidia. The wingless sandfish has less than 100 while the dragonfly boasts more than 30,000. The interesting thing about male insects is that they have more ommatidia then females. This makes them easily identifiable.
They have amazing body parts
One of the most diverse and varied groups of organisms on the planet is the insect family. Not only do they contribute to the economies of many countries, but they are also fascinating to humans and non-entomologists. Did you know that grasshoppers have ears on their belly? A grasshopper's hind legs also have special organs that allow it to jump. The grasshopper can leap the length of a basketball court. The grasshoppers are not only amazing in their bodies, but they also sound like the first creatures to make sounds.

Did you know that there are approximately 1.6 billion metric tons of trash produced every day in the world?
The United Nations states that an average person produces more than 2.5 pounds of waste per day. That's over 25 billion pounds of garbage each year!
Many of this trash ends in landfill dumps, or incinerators. But what happens if those dumpsters are full? It goes to the United States, where most of it is exported. It is then dumped in other countries, where it pollutes their ecosystems.But now, thanks to the work of one man, we know exactly where all this trash goes. Mike Sexton is his real name. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He reports back to us about the next steps.
Sexton claims he is very satisfied with his job. CNN spoke with Sexton that they have a lot fun. "We often see large rigs passing through our town and we will follow them. "Sexton began to follow truck drivers around 20 years ago.
"It's all I felt," he stated.
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton remembered, "The man was looking for somewhere to put the load." "He drove down the street and saw this building. He backed up and entered the building. "There were two large roll-off containers full of stuff. The man removed everything from the truck and started to load it again. "Then he took out everything and began to fill up the truck. There were many old tires, furniture, rags and mattresses. "It was just an absolute mess. But it was cleaned out before he came. There was no trash."
What is the explanation? The answer is that this location was once part of a recycling facility. People who knew about it would drive to this location to recycle their garbage. Sexton explained, "They would bring their household goods and take them here," and they would then empty the containers.
You might see this happen hundreds of times a day. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. The owner eventually abandons the vehicle.
However, trash is not the only problem on our planet.
Plastic pieces make up most of these particles. Others end up in rivers, oceans or the stomachss of fish.
Experts warn that if there is no change, the world could soon be facing a food shortage. Experts warn, "If you keep going like you're going," we could soon face a global food shortage. But most people don't seem to be worried, even though scientists are unanimous in warning us that the world is heading towards disaster.
These are five interesting facts about livers
The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It also helps regulate blood pressure and keeps our body temperature stable.
How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms could indicate liver problems.
You may notice symptoms such as dark urine, yellowing skin and fatigue. These aren’t the only warning signs. If you feel any of these warning signs, consult your doctor immediately.
The liver is an essential organ. It is an important organ that plays a vital role in detoxification.
-
The average adult liver weighs 1,400g.
-
A baby's liver is about half the size of an adult's at birth. It becomes about four times more large by the age of three than an infant's liver.
-
The liver is located just below the rib cage on the left side of the abdomen.
-
The liver is divided into 16 major lobes. However, there are many smaller lobules that are within these lobes.
-
There are approximately 10,000,000 red blood cells in the liver.
How does your brain control the functions within your body?
The brain sends messages to other organs and muscles to ensure they work together. Everything that happens within your body is controlled by the brain. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain is made of billions, or neurons, of nerve cells. Neurons communicate with each other by sending electrical signals called action potentials on axons. Every neuron has a cell wall around its nucleus. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. The neuron is lit by an electric charge created by the movement of ions.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. As a result, second neuron fires as well.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. An impulse travels along a synapse that connects the two neurons. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
They are vital for the communication between nerve cells. They coordinate brain activity among different parts.

Hollywood scandals that shocked all of the world
Nothing is more shocking that seeing someone be famous for their wrong reasons. There's nothing more shocking than watching someone fall from grace.
The best thing about watching how an industry reacts when it makes mistakes is the best part. We've all heard stories of celebrities who used drugs and alcohol excessively. Some even died young because of it.
The worst thing is when these stars are made public about their problems and shunned. This is where we ended up last week.
After a long and successful career, Heath Ledger finally succumbed to his demons. After a short battle with death, Heath Ledger succumbed to prescription pills.
His friends and family struggled to accept the loss of his son, while the media blasted him openly.
Heath was once one of the most gifted actors currently working. Two Academy Awards nominations were given to Heath for his role in Brokeback Mountain.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
Hollywood loved Heath. However, he quickly grew too large. He began to drink heavily and took drugs. He ended up in rehab and became clean.
Now that he was sober, it was time to make amends. So he made a documentary called "Room 237," which chronicled the making of The Shining. It was originally scheduled to release this year, but it won’t be available in theaters until next.
Every time Heath tried to get back into Hollywood, something happened. Heath was in fact arrested twice on drug charges.
We're not saying Heath should have been allowed back into show business. But it would have been nice to get some help before things spiralled out of control.
We hope Heath's story warns others who might think they can still have it all.
