Insecta is the class of insects called bugs. They are part of the Hemiptera group. Entomologists classify them as true bugs. They have hair, gills and four legs. So, you know what they look like, but did you know they have other characteristics as well?
Insects count as invertebrates
Invertebrates refer to bugs as having both living and dead parts. Insects are segmented and have chitin-based exoskeletons. Their body segments are organized into three main units: the head, thorax, and abdomen. Insects use these body segments to extract nutrients from their food. Catabolic reactions are used to digest food. They break down complex macromolecules into simple sugars, and then amino acids.
They are four-legged.
It is fascinating to observe that some insects have only four legs while others have six. For example, the locusts have only four legs while butterflies have six. To jump, insects use their front two pairs.
They have gills
Most people are likely familiar with the fact insects can have gills. Insects breathe through their gills. They are also a great way for insects to see the world around them. Although most insects have multiple visual units in their eyes, some species have hundreds of visual units. For example: Caterpillars have twelve sets of eyes and over 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. Both humans and non-entomologists can learn a lot from insects, which play a vital role in the environment and economy. Here are some interesting facts about insect jumping, including what they eat.
They produce methane
Methane is a greenhouse-gas that is released by insects 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 have ommatidia
The compound eyes of insects are composed of seven to eleven separate 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 male insects are distinguished by having more ommatidia (more than the females), which is quite interesting.
They have bizarre 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, for instance, that grasshoppers have ears attached to their abdomens? A grasshopper's hind legs also have special organs that allow it to jump. In fact, the grasshopper can jump the length of a basketball court. In addition to their extraordinary body parts, grasshoppers were also the first to make sound.

These are five interesting facts about livers

How does the brain control the functions in 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 your stomach to digest food and your lungs to breathe air; it tells your arms and legs to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Neurons communicate with each other by sending electrical signals called action potentials on axons. Every neuron has an outer cell membrane that surrounds its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. The electric charge that causes the neuron's fire is created by ion movement.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. As a result, second neuron fires as well.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. 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 coordinate activity between the different parts of your brain.
Which is the most mysterious spot on Earth?
Antarctica is one of the most mysterious places on Earth.
This is why we find it so captivating. 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.
Some of the most bizarre wildlife species can also be 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". Others believe it derives from Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to one source, one of the twins was conceived in winter. The term antarctic is derived from this.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the driest, windiest of all continents. It is too cold to support trees, plants, and animals.
Yet, this frozen wasteland is alive.
Here, 90 percent live of all species of living things. Here are approximately 50% of all the animal and plant species in the world.
And what makes Antarctica such a unique environment? Here, water freezes in ice rather that vaporizing into the atmosphere.
This results in large masses of ice floating above the ground.
These floating glaciers cover over 80%. They are growing in size every year.
The Antarctic ice has grown 60 feet so far since 1960.
If the melting continues, the sea level will rise by up to 200 feet. It could result in massive flooding all over the world.
Not everyone believes this is bad news. Some scientists think global warming might be beneficial. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
What is the reason actors are blacklisted?
As an actor, rejection is much more common than for writers. As an actor, it's likely that you will be rejected a lot. It doesn't matter, because you will eventually find someone you love.
Actors are usually very talented, meaning they can make a living almost anywhere. Actors don't really care about making money. Actors love to act and tell stories. You'll be an actor if you love acting.
Sometimes you may be told by the audition panel that you are too young, too old, or wrong for the role. You might also lose your audition for a film role. It happens all the time.
You may be criticised once your casting is complete. People will tell you that you look terrible or shouldn't be wearing makeup. If you're lucky, you won't even hear negative comments.
Sometimes, you might be criticised for playing a role that isn’t authentic or realistic. Perhaps you play a homosexual man and everyone thinks that you're straight. Or maybe you play a woman who is supposed to be tough, but she cries a lot.
Sometimes they might ask you to change how you speak. Sometimes they ask you to sound like either a boy or a girl. Most of the time, however, they want to hear better.
To ignore criticisms is the best way to respond. Actors feel like they've failed when told they did wrong. But the truth is that they haven't done anything wrong.
They weren't born with the talents that made them famous. And sometimes, no matter how hard they try, they don't fit the bill.
Blacklisting an actor could be for many reasons. Some people don't like actors. Some people think actors are lazy. Still, others say that actors are cheaters.
It doesn't matter what reason it may be, you won’t be banned if you keep trying. There are many roles available, and you will find them.
If you persevere, you will eventually succeed.
