Insecta refers to insects belonging to the Insecta class in the Hemiptera. They are classified as true bugs by entomologists. They are characterized by four legs, four legs, and hair. You know their appearance, but did you also know that they also have other unique characteristics?
Insects are invertebrates
Invertebrates can refer to insects as they have both living (and non-living) parts. Insects have segmented bodies and exoskeletons made of chitin. The head, thorax and abdomen are the main body parts. These body segments are used by insects to extract nutrients from food. Catabolic reactions are used to digest food. They break down complex macromolecules into simple sugars, and then amino acids.
They have four legs
It is quite interesting to observe that some insects only have four legs and others have six. For instance, locusts have four legs and butterflies six. For jumping, insects use the front pairs of their legs.
They have gills
Most people are likely familiar with the fact insects can have gills. They allow insects to breathe. They also allow them to see the surrounding environment. Many insects have multiple eyes. But some species have compound eye that can contain hundreds of different visual units. For example, caterpillars have 12 sets eye and 30,000 ommatidia.
They have long hair
If you are into bugs, then you need to be aware of the fact that they have hair. Insects are one of the most varied groups of animals. Their sheer number makes them fascinating to study. The role of insects in our environment is vital, as they are important for both human and non-entomologists. Here are some interesting facts about insects, including what they eat and how they jump.
They also produce methane
Methane, a greenhouse gas is released into the atmosphere from termites and other bugs. These creatures produce methane in their guts, and these gases are responsible for about 5 percent of global emissions. Although methane naturally occurs in the atmosphere, humans produce 320 million tonnes of methane every year. The biggest source of methane is from fossil fuel industries. This includes the production natural gas.
They have ommatidia
Insects have compound eyes that are made up of seven to eleven visual units. They can be used for many 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 insane body parts
The most diverse group of organisms in the universe is insects. Not only do they contribute to the economies of many countries, but they are also fascinating to humans and non-entomologists. Did you know, for instance, that grasshoppers have ears attached to their abdomens? A grasshopper's hind legs are equipped with special organs to allow for jumping. The grasshopper can leap up to twice the length of an NBA court. And, in addition to their amazing body parts, they were the first creatures to make sound.
FAQ
What is your most secretive community?
This question might surprise you. This may make you feel uncomfortable as it challenges your perception of reality and the way we live. However, there's a reason for this place to exist. It's not what we would expect.

I wanted to know more about the mysterious disappearing towns. What causes a community to disappear? How can one place become extinct?
It turned out that there are many theories about disappearing towns. One theory states that a town vanishes when all its buildings are destroyed. Another theory says that the town just moves. Another theory suggests that the town has never existed.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video looks into the history of those places and investigates their current status.

Why do actors end up on the blacklist?
Actors are more likely to be rejected than writers. An actor will probably be rejected quite often. It doesn't matter if you get rejected a lot because eventually you'll meet someone you love.
Actors are usually very talented, meaning they can make a living almost anywhere. But most actors don't want to make a lot of money. They love acting, and they love telling stories. Actors are likely to be outspoken.
Sometimes you may be told by the audition panel that you are too young, too old, or wrong for the role. Sometimes, you may lose an audition for a movie. That happens a lot.
After you've been cast, there may be criticism. People may tell you that your makeup looks terrible and you shouldn't use it. If you're lucky, you won't even hear negative comments.
Sometimes it's because you play a character that's not realistic or authentic. Perhaps you play a homosexual man and everyone thinks that you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Maybe you are asked to change your vocal chords. Sometimes they ask you to sound like either a boy or a girl. They will usually ask you to sound better.
Negative criticisms are best ignored. Actors often feel like they've failed if they're told they did something wrong. But they're not guilty of anything.
They just weren't born with the talent that made them famous. They may not fit the bill sometimes, no mater how hard they try.
There are lots of reasons why an actor could get blacklisted. Some people don't like actors. Others think that actors are lazy. Some actors may be cheaters.
No matter the reason, it is important to remember that you will not be blacklisted if there are other jobs available. There are many roles available, and you will find them.
Keep trying and you will eventually succeed.
How does the brain control the functions of your body?
The brain sends messages to other organs and muscles to ensure they work together. Your brain controls all that happens in your body. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Neurons communicate by sending electrical signals, called action potentials, on axons. Each neuron is covered by a cell membrane. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. Ion movement creates the electric charge that causes the neuron to fire.
When a neuron fires, chemicals called neurotransmitters are released into the space between the neuron and the next neuron. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. This causes the second neuron to fire too.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. The impulse travels along the synapse connecting the two neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
Communication within the nervous system is possible thanks to neurotransmitters. They coordinate activity between the different parts of your brain.
