Insecta are insects of the class Bug, which is part of the Hemiptera family. They are classified as true bugs by entomologists. They have four legs, gills, and hair. Now you're familiar with their physical appearance. But did you know that they also have other distinctive features?
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 segments allow insects to extract nutrients. They use catabolic reaction to digest their food, which breaks down complex macromolecules in simple sugars and provides amino acids.
They are four-legged.
It's fascinating to note that certain insects only have four legs, while others have six. For example: butterflies have six legs, while locusts just have four. To jump, insects use their front two pairs.
They have gills
Most people are aware of the fact that some insects have "gills". They allow insects to breathe. They can also be used to view the environment around them. Some species have compound eyes that combine hundreds of visual elements. While most insects have eyes composed of multiple visual units, others have complex eyes. For example, caterpillars have 12 sets eye and 30,000 ommatidia.
They have long hair
You need to know that bugs have hair. The most diverse animal group, insects, is the one that's worth studying. They play an important part in our environment, economy, and are fascinating to both humans as well as non-entomologists. Here are some fascinating facts about bugs, including how they jump and what they eat.
They also produce methane
Methane, also known as greenhouse gas, is released into atmosphere by termites and bugs. These insects produce methane from their stomachs and are responsible for approximately 5 percent of the global methane 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 can have compound eyes with seven to eleven different visual units. They are useful for many different purposes. There are some insects that have more ommatidia than others. For example, the wingless-silverfish has fewer that 100 ommatidia while the dragonfly has around 30,000. Interestingly, male insects have more ommatidia that females, which makes them easier to distinguish.
They have amazing body parts
Insects are one of the most diverse groups of organisms in the world. 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. It also has special organs on its hind legs to jump. The grasshopper can even jump as far as a basketball court. In addition to their extraordinary body parts, grasshoppers were also the first to make sound.
FAQ
What is the most mysterious location on Earth?
Antarctica is the world's most mysterious place on Earth.
Why do we find this place so intriguing? Because it is unlike any place on Earth.
It is remote, isolated, and extremely difficult to visit. It is not what you see.
These wild animals are also found in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it is "land of the ice". Some believe it means "land of ice". Others believe it is Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. According to one source, one of the twins was conceived in winter. The term antarctic is derived from this.
Others believe the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would be land turned away form the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the highest, coldest, windiest, dryest, and most populated continent. There are no trees, plants, or animals here because it is too cold.
Yet, life is abundant in this frozen wilderness.
It is home to approximately 90 percent of all life on Earth. About 50% of the world's plant and animal species can be found here.
What is the secret to Antarctica's unique environment? Here, water freezes into ice instead of evaporating into the air.
This causes large masses to form of ice which float high above the ground.
These floating glaciers make up 80%. They're getting bigger every year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
If the melting continues, sea level could rise up to 200ft. This could lead to massive flooding across the globe.
This does not mean that everyone is wrong. Global warming may be beneficial for some scientists. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils and bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
How does the brain control the functions of your body?
To ensure that other organs and muscle functions work together, the brain sends messages. Your body's functions are controlled by your 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 up billions of nerve cell networks connected in groups known as neurons. Action potentials are electrical signals that neurons send to one another. Every neuron has a cell wall around its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. 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. In turn, the second neuron also fires.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. The impulse travels along an synapse between the neurons. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
Neurotransmitters are important for communication within the nervous system. They also help coordinate activity between different parts of the brain.
Five interesting facts about your liver.
The liver is responsible of breaking down toxins and storing nutrients. It helps maintain a steady body temperature and regulates blood pressure.
We hear it all the time: "I feel sluggish today" or "my head feels heavy". These symptoms could indicate problems with your liver.
Common signs include yellowing skin, dark urine, fatigue, nausea and vomiting, weight loss, stomach cramps (yellow coloration), itching, and jaundice (yellow colouration). These are not all the warning signs. You should immediately consult your doctor if you have any of these symptoms.
The liver plays a crucial role in our lives. It plays a role in detoxification, digestion, metabolism, immunity, and reproduction.
-
An adult liver weighs around 1,400 grams.
-
At birth, a baby's liver is half the size of an adult. It can grow to four times the size of an infant's liver by the age 3.
-
The liver is located below the ribs on the left-hand side of your abdomen.
-
There are 16 main lobes in the liver, but many smaller lobules are inside the lobes.
-
Red blood cells make up approximately 10 million of the liver's total.
Is there a Hollywood blacklist?
There is a Hollywood blacklist.
The list isn’t available for public viewing. We don't know the names. But, here's why it matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. The studios would be out of business as they lose money. This would mean that they would cut back on movie production. That would reduce the opportunities for blacklisted filmmakers. Which would lead them to go bankrupt.
This could eventually lead to more victims.
A contract may be required to agree to not speak against employers if someone attempts to make an Oscar winning movie. Producers and directors who want to be nominated are subject to the same restrictions.
That's why you hear stories about how producers pressure directors to remove scenes from their films. Or directors threaten to walk out of projects that don’t match their vision.
This is the reason there is a Hollywood blacklist. Negative comments about your employer will most likely lead to you being unemployed. This is not good news for anyone.
Many people have been wrongly accused. They have had to fight for their freedom.
We must stop this from happening again. We must ensure that everyone has the right to express themselves freely.
We must get rid of the Hollywood blacklist.

How To
Hollywood scandals that shocked the globe
Nothing is more shocking than seeing someone famous for wrong reasons. There's nothing more shocking than watching someone fall from grace.
The best part is seeing how an industry reacts to its mistakes. We have all heard of celebrities who overdosed on drugs and alcohol. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. Last week, that's exactly where we were.
Heath Ledger died after a long, successful career. After a short battle with death, Heath Ledger succumbed to prescription pills.
His family and his friends struggled with the news and the media went after him.
Heath was once regarded as one of the best actors today. His performance in Brokeback Mountain earned him two Academy Awards nominations.
Heath, in addition to acting, also wrote and directed films such as A Knight's Tale (Monster's Ball) and Iron Man (3).
Hollywood loved Heath. But he was too big for his boots. He began using drugs and drinking heavily. He ended up in rehab and became clean.
He was now sober and wanted to make amends. He created a documentary called Room 237, which documented the making of The Shining. The film was originally supposed to be released in this year's theaters, but it will not make its way into the cinemas until next year.
Heath attempted to get into Hollywood every time. In fact, he was arrested twice on drug charges.
While we aren't saying Heath shouldn't have been allowed back in the show business, But it would have been nice to get some help before things spiralled out of control.
We hope Heath’s story can be an example to other people who believe they can still have it all.
