Insecta refers to insects belonging to the Insecta class in the Hemiptera. They are classified as true bugs by entomologists. They have hair, gills and four legs. You know their appearance, but did you also know that they also have other unique characteristics?
Insects belong to the invertebrates
Invertebrates include bugs, meaning that they can have both living parts and non-living ones. Insects have segmented bodies and exoskeletons made of chitin. The head, thorax and abdomen are the main body parts. 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 likely familiar with the fact insects can have gills. Gills are essential for insects to be able to breathe. They are also an excellent way to see the environment around them. Many insects have multiple eyes. But some species have compound eye that can contain hundreds of different visual units. For example, caterpillars have 12 sets eye and 30,000 ommatidia.
They have hair
If you are into bugs, then you need to be aware of the fact that they have hair. Insects make up the largest group of animals and are 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 fascinating facts about bugs, including how they jump and what they eat.
They produce methane
Methane is a greenhouse gas, which is released into the atmosphere by bugs, such as termites. Methane is produced by termites and other insects in their guts. They are responsible for around 5 percent global emissions. While methane can naturally occur in the air, methane from human activities is responsible for approximately 320 million tons each year. The largest source of methane emissions comes from fossil fuel industries, including the production of natural gas.
They have ommatidia
Insects have compound eyes made of seven to eleven individual visual units. They are used for a wide variety of purposes. Some insects have more than others. For example, the wingless-silverfish has fewer that 100 ommatidia while the dragonfly has around 30,000. The male insects are distinguished by having more ommatidia (more than the females), which is quite interesting.
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. Did you know, for instance, that grasshoppers have ears attached to their abdomens? It also has special organs on its hind legs to jump. The grasshopper can leap up to twice the length of an NBA court. In addition to their extraordinary body parts, grasshoppers were also the first to make sound.
FAQ
Did you know that there are approximately 1.6 billion metric tons of trash produced every day in the world?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? Where does all that rubbish go?Well, most of it gets shipped out of the country. It then gets dumped in foreign countries, polluting their ecosystems. However, now we know where all that trash goes. Mike Sexton is his nickname. He is the founder of Waste Watchers. He watches over trucks that transport trash across North America. He then gives us a report on what happens next.
Sexton says he finds his job very satisfying. CNN's Sexton said, "We have a lot to enjoy." "We often see large rigs passing through our town and we will follow them. "Sexton began following truckers almost 20 year ago.
"It's all I felt," he stated.
He loved the story of the driver who pulled into an abandoned gas station near Los Angeles. Sexton described, "The guy was looking somewhere to put his load." "He drove down the road and saw this building. He stopped and pulled up, then he went inside. "There were two enormous roll-off containers filled with stuff. The man removed everything from the truck and started to load it again. "Then he looked at the place and decided to unload everything. There were many old tires, furniture, rags and mattresses. "It was just an absolute mess. But it had been cleaned out before he came along. There wasn't any trash."
Why did this happen? This particular spot used to be a recycling center. People would drive there to recycle their trash. Sexton said that people would bring their household items to the building and then leave empty containers behind.
This could happen hundreds of time per week. The truck can be stopped running if it is so full of junk that it has to come back hundreds of times per week. And eventually, the owner decides to abandon the vehicle.
But, this isn't the only problem that our planet is facing.
Many of these tiny plastic pieces end up in landfills and incinerators. Some are washed into rivers and oceans. Others end up with fish in their stomachs.
Experts warn that the world may soon face a shortage of food if we don't make any changes. Experts warn that if we continue to go the same way, we won't make it. However, scientists and most people aren't worried.
Five interesting facts about your liver.
The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It also helps regulate blood pressure and keeps our body temperature stable.
Are you familiar with the expressions, "I feel sluggish today", or "my head feels heavy"? These symptoms may indicate problems with the liver.
You may notice symptoms such as dark urine, yellowing skin and fatigue. But these aren't the only warning signs. You should immediately consult your doctor if you have any of these symptoms.
The liver is an essential organ. It plays a role in detoxification, digestion, metabolism, immunity, and reproduction.
-
An adult liver weighs around 1,400 grams.
-
A baby's liver is about half the size of an adult's at birth. It becomes about four times more large by the age of three than an infant's liver.
-

What is the most fascinating fact about the human body
We have two eyes, two ears, two nostrils, four limbs, a mouth, a nose, and a penis. That's right, we have more than 50 parts of our bodies, but one thing is missing. A heart.
A heart is a pump that circulates blood throughout the body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.
Each minute, the heart pumps approximately 5 liters. This is equivalent of an adult drinking 2 to 3 cups of coffee each day.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. When you're asleep, your heart beats approximately 100 times per hour.
Skin color can be used to determine if someone has a medical condition. The capillaries are tiny blood vessels that can be seen on the skin's surface. These small vessels carry blood from the large blood vessel in the skin back towards the heart. The skin turns blue or violet when blood flow becomes blocked.
Red blood cells are missing in people with sickle-cell disease. Their blood becomes extremely sticky and hardened, which can lead to very serious illnesses.
If you cut yourself, a bandage is applied to stop the bleeding. For the wound to heal properly, blood must continue to flow. To do this, doctors insert a needle through the skin into the vein next to the injury. This allows blood flow to the area that has been injured.
A doctor can also insert tubes (catheters), into an artery in the vicinity of where blood clots form. This keeps the patient alive till the blood clot dissolves naturally.
What dark secrets can Hollywood keep from you?
Hollywood is full of secret societies. There are many secret societies in Hollywood. Some are cult-like, where members adhere to strict rules and rituals. Others are clubs for people who share similar 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 or guilds also represent producers, writers, actors, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. We shouldn't fear these people.
Instead, we should embrace them. Because they help us make better choices.
They tell us what movies will likely succeed, what songs will be popular, and what books will best sell.
They help us make decisions about what we will buy, watch, listen to, or read.
Because we can trust them, we can ignore their advice when it conflicts with our tastes.
They are more powerful than ever because we chose to ignore them. They are the supreme arbiters of taste.
You can ignore them if they don't agree with you.
Let's take a closer look at some of the less-known, yet still very real Hollywood secret clubs.
You'll see why they are so important.
