Insecta refers to insects belonging to the Insecta class in the Hemiptera. They are classified as true bugs by entomologists. They have four legs, hair, and gills. You may already know their looks, but did your know that they have other distinguishing characteristics?
Insects belong to the invertebrates
Bugs are invertebrates, which means that they have both living and non-living parts. Insects can be segmented with exoskeletons of chitin. The three major units of their body are the head, abdomen and thorax. Insects use these body segments to extract nutrients from their food. They digest their food through catabolic reactions, which break down complex macromolecules into simple sugars and amino acids.
They are four-legged.
It's interesting to see that not all insects have the same number of legs as others. For example: butterflies have six legs, while locusts just have four. For jumping, insects use their front pair.
They have gills
Most people are likely familiar with the fact insects can have gills. Gills are a way for insects to breathe. They are also a great way for insects to see the world around them. 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 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. Here are some fascinating facts about insects including their diet and jumping habits.
They produce methane
Methane is known to be a greenhouse chemical. It is released in the atmosphere by bugs such as termites. These bugs produce methane in the intestines of their animals, and they are responsible to about 5 percent worldwide emissions. While methane can naturally occur in the air, methane from human activities is responsible for approximately 320 million tons each year. The biggest source of methane is from fossil fuel industries. This includes the production natural gas.
They are ommatidia
Insects have compound eyes that are made up of seven to eleven visual units. They are useful for many different purposes. Some insects have a larger number of ommatidia than others. 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 crazy body parts
One of the largest groups of organisms worldwide, insects are among the most varied. Insects not only contribute to many countries' economies, but are also fascinating for humans and other non-entomologists. A grasshopper, for example, has ears on its stomach. A grasshopper's hind legs are equipped with special organs to allow for jumping. In fact, the grasshopper can jump the length of a basketball court. They are also the first animals to produce sound, thanks to their incredible body parts.
FAQ
What is the reason actors are blacklisted?
When you're an actor, there's more rejection than when you're a writer. Actors are likely to be rejected often. But it doesn't matter because eventually, you'll find someone who loves you.

What is the most mysterious location on Earth?
Antarctica is the world's most mysterious place on Earth.
We find this place so fascinating. Because it is unlike any place on Earth.
It is isolated, remote, and very hard to visit. But there is more to this site than meets the eye.
You will also find some of the oddest wildlife species in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
Antarctica's name is a mystery. Some believe it is "land of the ice". Others believe it comes from Greek mythology.
Antarktis, the Greek name for the island on which Zeus' twin brothers were conceived, was used in ancient Greece. One of the twins was said to have been born in winter. Thus, the term antarctic.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would be land turned away form the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the continent with the lowest, windiest and highest temperatures. Because it is so cold, there aren't any trees, plants or animals.
This frozen wasteland is still alive.
It houses approximately 90% of all Earth's living organisms. You can find approximately half the world's species of animal and plant plants here.
What is Antarctica? Here water freezes to ice and not evaporates into the atmosphere.
This causes large ice masses to rise above the ground.
These glaciers are responsible for covering 80% of the continent. And they're growing larger every year.
Since 1960, the Antarctic ice sheets has grown 60ft.
The sea level will rise up to 200 feet if melting continues. This could lead to massive flooding across the globe.
However, not all scientists believe this to be bad news. Some scientists claim that global warming could be good for us. According to scientists, global warming could be good for us because the melting of the ice sheets will accelerate, which can lead to floods that release toxic chemicals into our soil and bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
Is there a Hollywood blacklist.
There is a Hollywood blacklist.
The list is not made public. As far as we are aware, the names are not even known. But here's why it matters.
The reason behind the secrecy was that blacklisted directors and actors wouldn't be able find work. The studios would be out of business as they lose money. Which means they'd cut back on spending money on movies. This would result in fewer opportunities available for blacklisted filmmakers. They would then go bankrupt.
Which could ultimately result in more victims.
In short, when someone tries to make an oscar winning movie, they might be asked to sign a contract saying they won't speak publicly against their employers. Any director or producer who would like to be nominated for an award is subject to the same rules.
Producers often pressure directors to cut scenes from their films. Or directors threaten to walk out of projects that don’t match their vision.
This is why there is a Hollywood blacklist. You'll likely become unemployed if you say bad things about your employer. This is bad news for anyone.
The problem is that many people have been falsely accused. And they've had to fight to clear their name.
We need to stop this kind of thing before it starts happening again. We must ensure that everyone has the right to express themselves freely.
Also, we must take down the Hollywood blacklist.
What is the most surprising fact about your body?
Two eyes, two ears and two nostrils are part of our bodies. We also have four limbs: a mouth, nose, penis, and four limbs. You're correct, there are more than 50 parts in our bodies. But, one thing is missing. A heart.
A heart is a pump, which circulates blood throughout our bodies. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
Each minute, the heart pumps 5 liters of blood. This is equivalent to an adult consuming 2-3 cups of coffee per day.
The blood flows throughout the heart 24/7, 365 days a calendar. Your heart beats nearly 100 times a minute while sleeping.
Color of your skin is a good indicator of whether someone is healthy. You can see tiny blood vessels, called capillaries, when you look closely at the skin. These tiny vessels transport blood from the larger blood vessels to the heart. The skin becomes blue-colored or purple when blood flow is restricted.
People with sickle cell disease lack red blood cells. Their blood becomes sticky and hardens, causing them to become very ill.
If you cut yourself, a bandage is applied to stop the bleeding. For the wound to heal properly, blood must continue to flow. Doctors will insert a needle under the skin to access the vein near the injury. This allows blood drainage from the injury area.
The doctor may also insert catheters (catheters), into the artery at the site of the blood clot. This keeps the patient alive until the clot breaks up naturally.
