Did the chicken come first or the egg first? Why do cats often focus on the infinity? How does gecko skin change color? Let’s find the answers to these “no age limit” questions right here!
“First chicken or first egg?” This is probably one of the most famous “brain damage” questions at the moment. If you’re still stuck in the never-ending loop of this question, check out science’s answer!
The egg comes first! This is the solution that is based on current biological knowledge, as well as Darwin’s Theory of Evolution. Specifically, the closest ancestor of chickens cannot suddenly appear on their own, because “life comes from eggs”.
In addition, any transformation of the chicken ancestors to become the chickens of today will only take place in the embryonic stage, that is, when they are still in the egg.
In summary, the first chicken egg will appear first and from there will hatch the first chicken!
The dark spots that appear when we suddenly look at intense light are scientifically known as “blind spots” . Accordingly, when these light rays hit the eye, the retina’s light-receptive cells will be temporarily overloaded. So, for a short time initially, they are unable to respond to all incoming light, leading to the appearance of blind spots.
Scientists also recommend that, when you move from a dark space to a bright place, close your eyes for a few seconds in the transition to give your eyes time to prepare, thereby limiting the visibility. blind spot statue!
The fact that cats often focus on the unknown has led many people to speculate that they can see ghosts! The truth, however, is that the cat’s forward stare is just a preparatory step for them to go to sleep. Meanwhile, if the cat looks sideways, it means they heard or smelled something!
In the skin of the gecko there are pigment cells, which contain pigment granules. According to the scientists, this pigment cell is large enough for all types of pigment to be expressed at the same time.
However, in the case of a chameleon that needs to change color (camouflage, emotional expression, courting, etc.), the chromatophore will shrink and force the pigment needed into the cell center, resulting in a we’ll see the chameleon skin turn the color of that pigment.
The state of the body after waking up depends on many factors, not just the time of sleep! If the day before, you ate unhealthy foods, drank a lot of coffee, energy drinks, didn’t drink enough water or were inactive, you will still likely feel tired after a long sleep.
A long sleep cannot help you get the rest you need if you go to bed too late. According to scientists, the best bedtime is before midnight and it needs to be repeated as a habit. Besides, playing sports or being physically active can help you feel better when you wake up the next morning, even if you haven’t slept for eight hours.
