Insecta is the class of insects called bugs. They are part of the Hemiptera group. Entomologists classify them as true bugs. They have four legs and four gills. You may already know their looks, but did your know that they have other distinguishing characteristics?
Insects can be classified as invertebrates
Invertebrates include bugs, meaning that they can have both living parts and non-living ones. Insects can be segmented with exoskeletons of chitin. The head, thorax and abdomen are the main body parts. These body parts are used to extract nutrients. They use catabolic processes to digest their food. This breaks down complex macromolecules of sugar into simple sugars.
They are four-legged.
It is fascinating to observe that some insects have only four legs while others have six. For example, butterflies have six legs while locusts only have four. To jump, insects use their front two pairs.
They have gills
Most people are likely familiar with the fact insects can have gills. Gills allow insects to breathe. They can also be used to view the environment around them. Most insects have many visual units. However, some species have complex eyes with hundreds of visual unit. For example, caterpillars have 12 sets eyes and 30,000 ommatidia.
They have hair
If you're into bugs, you should know that they have hair on their bodies. Insects have the highest diversity of animals. This makes them a fascinating group to study. Humans and non-entomologists both find insects fascinating because they play a significant role in the economy and environment. Here are some interesting facts about insects, including what they eat and how they jump.
They produce methane
Methane, a greenhouse gas is released into the atmosphere from termites and other bugs. 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. The largest source of methane emissions comes from fossil fuel industries, including the production of natural gas.
They have ommatidia
Insects can have compound eyes with seven to eleven different visual units. They are used for a variety of purposes. Some insects have more or less ommatidia. The wingless silverfish, for example, has less than 100 ommatidia, while the dragonfly, on the other hand, has more than 30,000. Interestingly, male insects have more ommatidia that females, which makes them easier to distinguish.
They have insane body parts
One of the largest groups of organisms worldwide, insects are among the most varied. They are not only important for the economies of many countries but also provide fascinating information to both humans and non-entomologists. A grasshopper, for example, has ears on its stomach. In addition to this, its hind legs have special organs for jumping. The grasshopper can leap up to twice the length of an NBA court. They are also the first animals to produce sound, thanks to their incredible body parts.
FAQ
Is there a Hollywood blacklist.
There is a Hollywood blacklist.
But the list isn't made public. According to our knowledge, the names of these people aren't 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. This would result in studios losing money as the actors and directors would have to go out on their own. That would result in a reduction in spending on movies. This would lead to fewer opportunities and less money for blacklisted directors. Which would lead them to go bankrupt.
Which could ultimately result in 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. The same goes for any director or producer who wants to get nominated for an award.
Producers often pressure directors to cut scenes from their films. Directors may threaten to quit projects that don’t align with their vision.
This is why Hollywood keeps a blacklist. If you speak negatively about your employer, you will likely be fired. This is bad news for anyone.
There are many people who have been falsely accused. These people have had to fight to clear their names.
This kind of thing must stop before it can happen again. It is essential that everyone has the freedom to express their opinions.
We must get rid of the Hollywood blacklist.
What is the most mysterious place on earth?
Antarctica is home to the most mysterious and remote place on Earth.
Why do we find this place so intriguing? Because it is unlike anything else on Earth.
It is remote and difficult to reach. It is not what you see.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Some believe it means "land of ice." Others believe it comes out of Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to legend, one twin was born in winter. Therefore, the name antarctic.
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 has always been a fascination for people.
It is the continent with the lowest, windiest and highest temperatures. It is too cold for trees, plants and animals.
And yet, this frozen wasteland is teeming with life.
About 90 percent of all living things on Earth live here. It is home to approximately half of all world's animal and plant species.
And what makes Antarctica such a unique environment? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large ice masses to rise above the ground.
These glaciers are responsible for covering 80% of the continent. They continue to grow in size each year.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting continues, sea level could rise up to 200ft. This could lead to massive flooding across the globe.
Not everyone believes this is bad news. Some scientists believe that global warming can 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 cautioned that this theory sounds too science fiction.

Why do actors end up on the blacklist?
When you're an actor, there's more rejection than when you're a writer. An actor will probably be rejected quite often. It doesn't matter, because you will eventually find someone you love.
Actors have a lot of talent, so they can make a decent living almost anywhere. Most actors don't care about making money. Actors love acting and storytelling. So if you're an actor, chances are you're going to put yourself out there.
Sometimes, auditions are cancelled because you are either too young or too old for the job. Or you might audition for a movie and lose out to another person. It happens all the time.
After you've been cast, there may be criticism. Some people will say that you look awful or shouldn't wear makeup. If you're lucky, you won't even hear negative comments.
Sometimes you'll be criticized because you're playing a character that isn't realistic or authentic. Perhaps you're a gay man who everyone believes is straight. Maybe you are a woman who is tough but cries often.
Or maybe you're asked to change your voice. Sometimes, they will ask you to sound more like a woman or a man. Most times, though, they want you to sound better.
The best way to deal with these criticisms is to ignore them. Actors feel like they've failed when told they did wrong. They haven't done any wrong.
They were not born with the talent that would make them famous. Sometimes, no matter what they do, they just don't fit the bill.
Blacklisting can happen for many reasons. Some people don't like actors. Some people think actors are lazy. Others believe actors cheat.
No matter what the reason, you won't be blacklisted if your persistence persists. There are many opportunities for you to find your role.
If you persevere, you will eventually succeed.
