Insecta are insects of the class Bug, which is part of the Hemiptera family. Entomologists have classified them as true insects. They have four legs and four gills. So, you know what they look like, but did you know they have other characteristics as well?
Insects count as invertebrates
Bugs are invertebrates, which means that they have both living and non-living parts. Insects are segmented and have chitin-based exoskeletons. The main parts of their bodies are divided into the abdomen, head, and thorax. 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 quite interesting to observe that some insects only have four legs and others have six. For example, the locusts have only four legs while butterflies have six. Insects use their front pairs for jumping.
They have gills
Most people know that certain insects have gills. Gills are a way for insects to breathe. They also allow them to see the surrounding 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're into bugs, you should know that they have hair on their bodies. Insects are the most diverse group of animals, and their sheer population makes them an interesting group 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 known to be a greenhouse chemical. It is released in the atmosphere by bugs such as termites. These creatures produce methane in their guts, and these gases are responsible for about 5 percent of global emissions. While methane is naturally occurring in the atmosphere, human activities account for 320 million tons of methane each year. Natural gas production is the largest source of methane.
They have ommatidia
Insects have compound eyes that are made up of seven to eleven visual units. They are useful for many different purposes. Some insects have more than others. The wingless sandfish has less than 100 while the dragonfly boasts more than 30,000. Interestingly, male insects have more ommatidia that females, which makes them easier to distinguish.
They have some of the most bizarre body parts
The most diverse group of organisms in the universe is insects. Not only do they contribute to the economies of many countries, but they are also fascinating to humans and non-entomologists. One example is the fact that grasshoppers can have ears on their stomachs. It also has special organs on its hind legs to jump. The grasshopper can leap the length of a basketball court. The grasshoppers are not only amazing in their bodies, but they also sound like the first creatures to make sounds.

Is there a Hollywood blacklist of actors?
There is a Hollywood blacklist.
The list isn’t available for public viewing. As far as we know, the names aren't even known. Here's why this 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. Which means they'd cut back on spending money on movies. That would reduce the opportunities for blacklisted filmmakers. This would make them bankrupt.
This could eventually lead to more victims.
If someone attempts to make an Oscar-winning movie, they may be asked to sign a contract stating that they will not speak out against their employers. This applies to any producer or director who wishes to be nominated.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Directors might threaten to leave projects that don't reflect their vision.
This is why Hollywood has created a blacklist. Negative comments about your employer will most likely lead to you being unemployed. And that's not good for anyone.
There are many people who have been falsely accused. They have had to fight for their freedom.
This is unacceptable behavior and must be stopped. We need to ensure everyone has the right of expression.
Also, we must take down the Hollywood blacklist.
Why do actors end up on the blacklist?
An actor is more likely to get rejected than a writer. Actors are likely to be rejected often. However, it doesn't really matter as you will eventually meet someone who is truly your love.
Actors are typically very talented and can earn a living virtually anywhere. But most actors don't want to make a lot of money. They love acting, and they love telling stories. It's likely that you will be acting if your passion is acting.
Even worse, you might be told you are too young or too old to play the part. Or, you could lose out on a role in a movie. It happens all the time.
Once you've been cast you might also be subject to criticism. Many people will tell you you look horrible or that you shouldn't be wearing make-up. If you're lucky, you won't even hear negative comments.
Sometimes it's because you play a character that's not realistic or authentic. Perhaps you're a gay man who everyone believes is straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Sometimes, they ask you to change your voice. Sometimes, they want you to sound more like a man or a woman. They want you to sound better most of the time.
To ignore criticisms is the best way to respond. Actors often feel like they've failed if they're told they did something wrong. The truth is they haven’t done anything wrong.
They didn't have the talent to make them famous. And sometimes, no matter how hard they try, they don't fit the bill.
An actor can be blacklisted for many reasons. Some people don't like actors. Others think that actors are lazy. Others think actors are lazy.
Whatever your reason, it doesn't matter. You won't get blacklisted for trying. There are many jobs out there and you'll be able to find them.
If you persevere, you will eventually succeed.
Which is the most mysterious spot on Earth?
Antarctica is one of the most mysterious places on Earth.
We find this place so fascinating. Because it is unlike any other spot on Earth.
It is isolated, remote, and very hard to visit. This site has more to it than meets your eye.
You'll also find the strangest species of wildlife in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
Antarctica is not known by anyone. Some say it means "land on ice." Some believe it means "land of ice". Others believe it is 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. This is why the word "antarctic" was chosen.
Others believe that it is the Greek word anti, which means against, and tropos, which refers to turning. This would mean that the land was turned away by the sun.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the coldest, windiest, driest and highest continent. There are no trees, plants, or animals here because it is too cold.
And yet, this frozen wasteland is teeming with life.
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 to ice and not evaporates 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.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting continues, sea level could rise up to 200ft. This could lead to widespread flooding.
Not everyone believes this is bad news. Some scientists claim that global warming could be good for us. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others warn that this theory sounds like something out of a science-fiction movie.
Statistics
- In fact, according to the American Academy of Ophthalmology, you make 15 to 30 gallons of tears each year, which is insane when you think about it. (romper.com)
- You spend about 10% of your time awake blinking (romper.com)
- In one 2014 study published in the Archives of Medical Science that sought to study the prevalence of these mites, research showed that 41% of the people had them hanging out in their eyelashes. (romper.com)
- Your mouth makes a lot of saliva every day It might seem like way too much, but your salivary glands typically produce anywhere from 0.5 and 1.5 liters a day, according to a 2009 study published in the Journal of Medicine and Life. (romper.com)
- It might not sound like something that's truly plausible — and it is quite rare — but according to a 2015 study published in the Asian Cardiovascular & Thoracic Annals, it's possible to hurt yourself and even break a rib just by sneezing. (romper.com)

Hollywood scandals that shocked all of the world
There is nothing more shocking than witnessing someone get famous for the wrong reasons. However, there is nothing worse than watching them fall from grace.
The best thing about watching how an industry reacts when it makes mistakes is the best part. There are many stories about celebrities who drank excessively. Some even died young because of it.
The worst thing is when these stars are made public about their problems and shunned. Last week, that's exactly where we were.
Heath Ledger lost his long and successful career. He overdosed on prescription pills, and after a brief battle with death, he passed away.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once considered to be one of today's most talented actors. Two Academy Awards nominations went to Heath for his performance on Brokeback Mountain.
Heath did more than act. He also directed films including A Knight's Tale. Monster's Ball and Iron Man.
Hollywood loved Heath, however he soon grew too big for his good looks. He began using drugs and drinking heavily. He eventually went to rehab and was clean.
After he had gotten sober, he decided to make amends. He created a documentary called Room 237, which documented the making of The Shining. It was originally scheduled to release this year, but it won’t be available in theaters until next.
Heath tried unsuccessfully to get into Hollywood again, but nothing happened. Heath was in fact arrested twice on drug charges.
We are not suggesting that Heath should be allowed back into the show business. However, it would be nice if he could get some help before things spiral out of control.
We hope Heath’s tale will be a wakeup call to anyone who may believe that they can still have all.
