Insecta (or bug) is a class of insects in the Hemiptera. Entomologists have classified them as true insects. They have four legs, gills, and hair. 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 can be segmented with exoskeletons of chitin. The main parts of their bodies are divided into the abdomen, head, and thorax. These body sections are used by insects for extracting nutrients from their food. 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 is quite interesting to observe that some insects only have four legs and others have six. For example, locusts are only four inches taller than butterflies. For jumping, insects use the front pairs of their legs.
They have gills
Most people know that certain insects have gills. They allow insects to breathe. They are also an excellent way to see the environment around them. While most insects have eyes that are made up of many visual units, some species have compound eyes made up of hundreds of visual units. For example, caterpillars have 12 eyes and 30,000 eye ommatidia.
They have hair
If you are interested in bugs, it is important to understand that their bodies have hair. Insects are one of the most varied groups of animals. Their sheer number makes them fascinating to study. Insects play an important role in our environment and economy, and they're interesting to both humans and non-entomologists alike. Here are some interesting facts about insect jumping, including what they eat.
They produce methane
Methane is known to be a greenhouse chemical. It is released in the atmosphere by bugs such as termites. These insects produce methane from their stomachs and are responsible for approximately 5 percent of the global methane emissions. While methane is naturally occurring in the atmosphere, human activities account for 320 million tons of methane each year. Fossil fuel industries (including the production of natural gas) are the largest sources of methane.
They are ommatidia
The compound eyes of insects are composed of seven to eleven separate visual units. They are used for a variety of purposes. Some insects have more or less ommatidia. For example, the wingless-silverfish has fewer that 100 ommatidia while the dragonfly has around 30,000. It is interesting to note that male insects are more distinguishable than their female counterparts.
They have amazing body parts
One of the largest groups of organisms worldwide, insects are among the most varied. They not only make a significant contribution to the economies in many countries, but they also offer fascinating experiences for both humans and nonentomologists. For example, did you know that a grasshopper has ears on its belly? The grasshopper also has special organs in its hind legs for jumping. The grasshopper can leap up to twice the length of an NBA court. They were also the first creature to use sound to communicate their body.

Which is the most mysterious spot on Earth?
Antarctica is the most mysterious continent on Earth.
We find this place so fascinating. It is unlike any other place on Earth.
It is difficult to access because it is remote and extremely isolated. It is not what you see.
These wild animals are also found in this natural wonder.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it refers to "land of ice". Others believe it comes from Greek mythology.
Antarktis was an ancient Greek name that was given to the island where Zeus and his twin brothers, Zeus. According to some legends, one of these twins was born in winter. Therefore, the name antarctic.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would mean that the land was turned away by the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is the continent with the lowest, windiest and highest temperatures. It is too cold for trees, plants and animals.
Yet, this frozen wasteland is alive.
About 90 percent of all living things on Earth live here. There are about 50% of the world's animal, plant and plant species.
What makes Antarctica so special? Here, water freezes into ice instead of evaporating into the air.
This creates large masses of ice that float above the ground.
These glaciers are responsible for covering 80% of the continent. And they're growing larger every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
The sea level could rise to 200 feet if the melting continues. This could lead to massive flooding across the globe.
But not everyone thinks this is bad news. Some scientists believe that global warming can be beneficial. They say that as temperatures rise, the ice sheets might melt faster, causing floods that flush out tons of toxic chemicals from our soil and bodies.
But others warn that this theory sounds like a plot from a science fiction movie.
How does the brain control the functions in your body?
The brain relays messages to other parts of the body to ensure their functionality. Everything that happens within your body is controlled by the brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. Action potentials on Axons are an electrical signal that neurons send to each other. Each neuron has its own cell membrane around its nucleus. There are channels within the membrane that allow ions such a sodium or potassium to enter and exit the cell. Ion movement is what causes the neurons to fire.
Neurotransmitters, which are chemicals that release neurotransmitters when a neuron fires up, can be found in the space between the neurons and the next one. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. As a result, second neuron fires as well.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. The impulse travels along an synapse between the neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
The nervous system relies on neurotransmitters for communication. They coordinate brain activity among different parts.

How To
Secret societies and clubs in American history
For many reasons, secret societies and clubs of American History are fascinating. They are mysterious because of this. Their impact on our society is another reason.
American history has seen secret societies and clubs used to promote ideas that were otherwise taboo. Anti-Semitism is one example of such ideas. These groups also promoted political ideologies such communism, socialism, and other socialist ideas.
The Ku Klux Klan, the most famous American organization, is also the most important. This group was formed after the Civil War ended in 1865. It was created to protect white men against African Americans.
Other organizations that were created in this period include the Knights Templar (Freemasons), and Odd Fellows. These groups all shared similar goals and beliefs.
Another interesting aspect about secret societies is their ability to restrict memberships to men only. However, these groups had some female members. These women included Emma Goldman. Margaret Sanger. And Susan B Anthony.
The ideals shared by the secret societies mentioned earlier were not shared by all. The Order of Skull & Bones is an example of a secret society that was established in 1832. Their goal was to create an elite class within the United States.
