Insecta refers to insects belonging to the Insecta class in the Hemiptera. Entomologists call them true bugs. They have hair, gills and four legs. They look familiar, but did know that there are other features?
Insects make up invertebrates
Invertebrates can refer to insects as they have both living (and non-living) parts. Insects have segmented bodies and exoskeletons made of chitin. The main parts of their bodies are divided into the abdomen, head, and thorax. These body segments allow insects 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 interesting to note that some insects only have four legs, but others have six or more. For example, the locusts have only four legs while butterflies have six. To jump, insects use their front two pairs.
They have gills
Most people are aware of the fact that some insects have "gills". Gills are a way for insects to breathe. They also allow them to see the surrounding environment. Although most insects have multiple visual units in their eyes, some species have hundreds of visual units. For example, caterpillars have 12 sets eye and 30,000 ommatidia.
They have long hair
If you are interested in bugs, it is important to understand that their bodies have hair. 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. These are some fun facts about insects: what do they eat? How do they jump?
They produce methane
Methane, also known as greenhouse gas, is released into atmosphere by termites and bugs. About 5 percent of global methane emissions comes from these creatures, which produce methane through their guts. Methane can be found in the atmosphere naturally, but human activities produce approximately 320,000,000 tons of methane annually. Fossil fuel industries (including the production of natural gas) are the largest sources of methane.
They have ommatidia
The compound eyes of insects are composed of seven to eleven separate visual units. They are useful for many different purposes. Some insects have more ommatidia then others. 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 than females, making them more easily distinguishable.
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. Did you know that grasshoppers have ears on their belly? It also has special organs on its hind legs to jump. The grasshopper can leap up to twice the length of an NBA court. The grasshoppers are not only amazing in their bodies, but they also sound like the first creatures to make sounds.
FAQ
What is the most surprising fact about your body?
We have two eyes and two ears, two nostrils each, four limbs, four limbs and a penis. Yes, more than 50 parts to our bodies. But one thing is missing. A heart.
The heart is a pump that circulates blood throughout your body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.
The heart pumps out about 5 liters per minute. This is equivalent in daily coffee consumption to an adult who consumes approximately 2 to 3 cups.
The heart pumps blood 24 hours a days, 365 days per year. Your heart beats nearly 100 times a minute while sleeping.
Color of your skin is a good indicator of whether someone is healthy. The capillaries are tiny blood vessels that can be seen on the skin's surface. These tiny vessels transport blood from the larger blood vessels to the heart. The skin becomes blue-colored or purple when blood flow is restricted.
People with sickle cells lack red blood cell. Their blood becomes very sticky and hardened, leading to serious illness.
To stop bleeding from a cut, you can apply a bandage to the wound. The wound must remain open for blood to flow properly. To do this, doctors insert a needle through the skin into the vein next to the injury. This allows blood drainage from the injury area.
Doctors may also insert catheters (catheters), in an artery to treat a blood clot. This keeps the patient alive till the blood clot dissolves naturally.
What is the most mysterious location on Earth?
Antarctica is considered the most mysterious area on Earth.
Why is this place so amazing? Because it is unlike anything else on Earth.
It is very remote and isolated. This site has more to it than meets your eye.
This natural wonder is also home to some of the strangest wildlife species.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica, The South Pole
Antarctica is named for no one. Others believe it means "land with ice". Others believe it comes from Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. According to one source, one of the twins was conceived 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 be land turned away form the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. Because it is so cold, there aren't any trees, plants or animals.
This frozen wasteland is still alive.
It houses approximately 90% of all Earth's living organisms. You can find approximately half the world's species of animal and plant plants here.
What is it that makes Antarctica so unique? Here, water freezes and becomes ice instead of evaporated into the air.
This results in large masses of ice floating above the ground.
These floating glaciers cover 80% of the continent. They're getting bigger every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
The sea level will rise up to 200 feet if melting continues. This could lead to widespread flooding.
But not everyone thinks this is bad news. Some scientists claim that global warming could be good for us. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils 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?
To ensure that other organs and muscle functions work together, the brain sends messages. 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. Neurons communicate by sending electrical signals, called action potentials, on axons. Each neuron has its own cell membrane around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. Ion movement is what causes the neurons to fire.
When a neuron fires, chemicals called neurotransmitters are released into the space between the neuron and the next neuron. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. This causes the second neuron to fire too.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. The impulse travels along an synapse between the neurons. The transmitter binds at the receptors of the post-synaptic Neuron and triggers its firing.
They are vital for the communication between nerve cells. They are also responsible for coordinating activity between various parts of the brain.
These are five interesting facts about livers
The liver is responsible to detoxify toxins and store vitamins and minerals. It also regulates blood pressure, and maintains our body's temperature.
How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms could be signs of liver problems.
Common signs include yellowing skin, dark urine, fatigue, nausea and vomiting, weight loss, stomach cramps (yellow coloration), itching, and jaundice (yellow colouration). These aren't all warning signs. If you experience any of them, make an appointment with your doctor immediately.
The liver is an essential organ. It is vital for detoxification, metabolism, immunity, reproduction, and digestion.
