Answers to these questions that science can answer
Although chickens have largely lost their ability to fly, they still have features similar to those found in other birds and can fly short distances.
Domestic rearing of chickens and years of selective breeding is responsible for the loss of their ability to fly.
In this article, we will look for answers to these questions that science can answer.
Do fish blink eyes?
No. Like snakes, they do not have moving eyelids. Instead, they have an invisible shell over their eyes. Fish have very sharp eyes and can see things we can't see. They rely on visual cues to identify any creature, choose a mate, and defend their territory.
When a cat is fat, does its mustache grow longer?
No. The length of a cat's mustache depends on its genes. If a cat is fat, its mustache becomes smaller as a guide to its size. If a cat's mustache is telling it that it can pass through a narrow space, it may get stuck there.
Do bats make loud noises?
Bats make noises but our ears cannot hear them. Bats make a very loud noise called ultrasound. Like dolphins and whales, bats use sound to find their prey and find their current place and wherever they want to go. This method is called echolocation. The sound that bats make makes an echo of buildings, trees, animals, and other objects. On hearing this, bats decide how far away something is. And what is its nature?
That means bats can hear their voices, but we can't.
Do giraffes have valves in their arteries that prevent the blood circulating in their neck from returning to their heart?
No. But that doesn't happen to any animal. Giraffes are mammals just like humans. In terms of anatomy and internal organs, almost everything is the same (but the volume may be different). This circulatory system is based on a pump (heart) that keeps blood flowing in the arteries. These arteries are connected to the tiny blood vessels by large veins. There are no valves in the arteries but in the veins.
When blood comes out of the heart, it moves with a lot of pressure, so it doesn't need a valve to ensure it travels in one direction. This pressure decreases in the veins. There is a chain of valves to stop the flow of blood back to the heart which stops this flow.
Are dogs better able to smell than humans?
Dogs are thought to be millions of times better able to smell specific odors than humans. There are several reasons for this.
A dog's nose is four times bigger than ours. While there are 5 million ethmoidal (olfactory) cells in a human nose, some dogs have more than 200 million in their noses.
A dog's nose is designed to smell. It is large and wet which collects and dissolves fragrance particles.
When a dog smells something, its saliva starts to flow. This wet tongue works to collect and dissolve more fragrance particles.
How many teeth does the Great White Shark have?
The front teeth of sharks are constantly changing with the teeth growing behind them. The front row of an adult Great White Shark has an average of three to 24 teeth.
Each tooth has a second tooth to replace it, so a shark has 60 to 68 teeth in its mouth, of which only half are in use.
Why can't chickens fly?
Although chickens have largely lost their ability to fly, they still have features similar to those found in other birds and can fly short distances.
They have ventilators around their lungs that help them breathe, while their bones also have air cavities that help them lose weight to fly.
Domestic rearing of chickens and years of selective breeding is responsible for the loss of their ability to fly.
Archaeological evidence shows that chickens have been domesticated for thousands of years in human populations in Pakistan and India from 320 BC.
They were chosen because of the quality of their flesh, the white flesh on their chests, and perhaps the bad ability to fly. This unnatural choice, made over the centuries, has come to the fore in the form of the current rooster, which is very bad at flying.
