Insecta refers to insects belonging to the Insecta class in the Hemiptera. Entomologists have classified them as true insects. They have four legs, gills, and hair. You know their appearance, but did you also know that they also have other unique characteristics?
Insects can be classified as invertebrates
Invertebrates can refer to insects as they have both living (and non-living) parts. Insects are segmented and have chitin-based exoskeletons. The three major units of their body are the head, abdomen and thorax. These body segments are used by insects to extract nutrients from food. They use catabolic reaction to digest their food, which breaks down complex macromolecules in simple sugars and provides amino acids.
They have four legs
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. To jump, insects use their front two pairs.
They have gills
Most people are probably familiar with the fact that some insects have gills. Gills allow insects to breathe. They allow insects to see their environment. Many insects have multiple eyes. But some species have compound eye that can contain hundreds of different visual units. For example: Caterpillars have twelve sets of eyes and over 30,000 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. Both humans and non-entomologists can learn a lot from insects, which play a vital role in the environment and economy. Here are some fascinating facts about bugs, including how they jump and what they eat.
They produce methane
Methane is a greenhouse-gas that is released by insects such as termites. Methane is produced by termites and other insects in their guts. They are responsible for around 5 percent global emissions. Although methane naturally occurs in the atmosphere, humans produce 320 million tonnes of methane every year. Natural gas production is the largest source of methane.
They are ommatidia
Insects have compound eyes made of seven to eleven individual visual units. They are used for a variety of purposes. There are some insects that have more ommatidia than others. The wingless sandfish has less than 100 while the dragonfly boasts more than 30,000. Interestingly, male insects have more ommatidia than females, making them more easily distinguishable.
They have insane body parts
One of the most diverse and varied groups of organisms on the planet is the insect family. Insects not only contribute to many countries' economies, but are also fascinating for humans and other non-entomologists. For example, did you know that a grasshopper has ears on its belly? It also has special organs on its hind legs to jump. The grasshopper can actually jump up to the length of a basketball court. And, in addition to their amazing body parts, they were the first creatures to make sound.
FAQ
What is the most mysterious place on earth?
Antarctica is one of the most mysterious places on Earth.
This is why we find it so captivating. Because it's unlike any other place in the world.
It is isolated, remote, and very hard to visit. This site has more to it than meets your eye.
Some of the most bizarre wildlife species can also be found in this natural wonder.
So let's explore how this remarkable destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is not known by anyone. Some say it means "land on ice." Others think it comes 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. Hence, the word antarctic.
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.
Whatever the reason, Antarctica has always held a special fascination for people.
It is the driest, windiest of all continents. Because it is so cold, there aren't any trees, plants or animals.
Yet, life is abundant in this frozen wilderness.
About 90 percent of all living things on Earth live here. About 50% of the world's plant and animal species can be found here.
What is Antarctica? Here, water freezes into ice instead of evaporating into the air.
This results in large masses of ice floating above the ground.
These glaciers are responsible for covering 80% of the continent. They're getting bigger every year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead worldwide flooding.
However, not all scientists believe this to be bad news. Some scientists suggest that global warming could actually be good for us. 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.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
How does the brain regulate the functions of the body?
To ensure that they work together, messages are sent by the brain to other organs. Everything that happens within your body is controlled by the brain. It tells you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron is covered by a cell membrane. 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.
Neurotransmitters are chemicals released when a neuron fires. 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. An impulse travels along a synaptic link between the two neuron. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
They are vital for the communication between nerve cells. They coordinate brain activity among different parts.
Is there any Hollywood blacklist for actors?
There is an Hollywood blacklist.
However, the list isn’t public. As far as we are aware, the names are not even known. 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. That would result in a reduction in spending on movies. Which would mean fewer opportunities for the blacklisted filmmakers. They would then go bankrupt.
This could mean more victims.
In other words, if someone is trying to make an Oscar winning movie, they might have to sign a contract that says they won't speak openly against their employers. Any director or producer who would like to be nominated for an award is subject to the same rules.
That's why you hear stories about how producers pressure directors to remove scenes from their films. Directors may threaten to quit projects that don’t align with their vision.
This is why there is a Hollywood blacklist. If you make negative comments about your employer, it's likely that you will be unemployed. And that's not good for anyone.
There are many people who have been falsely accused. And they've had to fight to clear their name.
This is unacceptable behavior and must be stopped. Everybody should be able to freely express themselves.
We must get rid of the Hollywood blacklist.
What dark secrets are there in Hollywood?
Hollywood is filled secret societies. Some are cult-like groups where members follow strict rules and rituals, while others are simply clubs for those who share common interests.
There are other nefarious entities that have a significant influence on the industry. These include the MPAA (Motion Picture Association of America), the organization that sets film ratings and RIAA(Recording Industry Association of America), the company that sets music licensing fees.
Numerous unions, guilds, and associations represent actors, writers, producers, editors, and other creative professionals. Many of the major TV networks and movie studios are owned or controlled by large corporations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. But that doesn't mean we should fear them.
Instead, we should embrace these facts. Because they help us make better choices.
These people tell us what movies and songs will succeed, and which books will sell best.
They are, in short, what help us choose what we will watch, read and listen too.
We can trust them so we can ignore their advice when it doesn't suit our taste.
They are more powerful than ever because we chose to ignore them. They become the ultimate arbiters for taste.
You are free to ignore their messages if that bothers you.
Let's now take a look into some lesser-known but very real Hollywood secret societies.
Observe why they are important.
