There are also questions that people find it inconvenient to ask someone. Do you know why there is a dimple between the nose and the upper lip?
Why do some mosquitoes bite more than others? It turns out that such questions were asked, and the Internet has answers!
1. Why do people have eyes of different colors?
This condition is called complete heterochromia
This is a very big rarity. This happens only in 11 out of 1,000 Americans
A similar phenomenon may be the result of a lack or excess of melanin. A number of factors can lead to complete heterochromy. Such a state can be transmitted from one generation to another.
According to scientists, the most common cause is the absence of genetic diversity
Gene mutations that determine the correct distribution of melanin can be damaged by chromosomal homogeneity.
2. Why are our buttocks round in shape?
Some people are obsessed with maintaining the excellent shape of their buttocks, but have you ever wondered why they are rounded?
Buttocks of circular shape are the result of the process of evolution
We know that our ancestors were hunters – they caught game for food. So the muscles were formed quite naturally.
The round shape also helps the correct posture
But what is most interesting in the form of our buttocks, is that they prevent the leakage of unpleasant odors. And all thanks to the extra flesh, which just creates an appetizing form
3. Why is there a hollow between the upper lip and nose?
This hollow is called the labial groove
It appears as a result of the formation of the face still in the womb.
At this time, various parts of the face are together
Sometimes the upper lip may not merge, resulting in the cleft palate
Why do wrinkles appear on the fingers if they are held in water for long?
The skin of the hands is covered with sebum, the secret of the sebaceous glands, which retains the moisture of the hands and protects the outer layer.
Wrinkled fingers are the result of a reaction in the autonomic nervous system
When the fingers are in the water for a long time, the sebum is washed off
The appearance of wrinkles is the result of the fact that the skin is impregnated with water. Some scientists believe that wrinkles exist in order to keep fingerprints if the hands become wet.
5. Why do some people bite mosquitoes more than others?
You are probably interested in the question of why your friend, who is with you in the same room, has never bitten a mosquito? Apparently, these insects determine their prey depending on several factors.
Their choice can be influenced by age, habits, clothing, type of blood and what a person drinks
Mosquitoes draw more towards people, the first blood group, since this type emits signals about themselves. Mosquitoes can choose a more active person, because they like sweat and warmth.
In addition, these insects, as a rule, choose those who wear dark clothes.
And, finally, it is more likely that a mosquito will bite someone who likes to drink beer.
