The bones of birds are not completely empty. They are lighter in weight and have air pockets. The bone marrow in birds, like that of other animals, produces red and white blood cells, but the location and distribution of the marrow is different due to the unique structure of bird bones. HSCs are primarily found in the bone marrow of birds, which is a spongy tissue found within the bones. However, some studies have suggested that HSCs may be present in other tissues in certain bird species, such as the liver and spleen.

Because sand particles are larger and more rigid than clay particles. Sand helps to create gaps or voids between the clay particles, which act as channels for the water to escape as it dries. This allows the clay to shrink more evenly, which reduces the possibility of cracking.

Let me guess the ingredients.I guess, they are onion, garlic, carrot diced, potatoes ,Bockwurst , vegetable oil , salt, white pepper, black Pepper.

Amazing. It seems to be very tasty. You have increased my craving for pizza.

>Why does temperature determine the sex of certain egg laying animals like crocodiles?

well explained . I have also go through the topic TSD. It is also true that a lot of work has left to be done on this mechanisms .

Known as Pão de queijo in Brazil.It is most probably most export food of Brazil. It is so yummy. My mouth fills with water after watching this.

The typical colour range of urine is from light yellow to deep amber. The urobilin pigment, commonly known as urochrome, is the main cause for this colour.The colour of the pigment depends on whether your pee is water-diluted or more concentrated. The colour of your urine gets lighter as you drink more water and become more hydrated.
The chemicals and pigments in the foods you consume, as well as the drugs you take, also affect the colour of your urine. These modifications are fairly common and generally pass quickly.
An underlying medical problem may be indicated by certain colour changes.

what! Is it an egg, and there seems to be some meat pieces in the middle?

That's a good question.... I'll explain it to you scientifically.
The human body has a natural system called acid-base balance that helps to keep the pH label stable. It is essential for the normal operation of biological processes. There are three major organs in our human body that help to regulate the balance. They are the liver, the kidneys, and the lungs. The PH of our bodies is 7.35-7.45 (as you mentioned). This means that our bodies are slightly alkaline. Our bodies have a variety of buffer systems made of various chemicals. These chemicals can absorb excess acid or base to maintain a normal ph level in the body.
One of the most important buffering systems in the body is the bicarbonate buffer system, which helps to neutralise excess acid in the blood.The kidneys help to maintain the body's acid-base balance by controlling blood levels of bicarbonate and other acids.
While some parts of the body are naturally acidic in order to aid digestion, the rest of the body requires a slightly alkaline pH in order to support normal cellular function. When the pH of the body becomes too acidic or alkaline, it can lead to a number of health issues including metabolic acidosis or alkalosis, which can be fatal if not treated.

the answer is definately "No". But it may be possible in future.
We actually lose DNA as we get older. When a cell divides, its chromosomes become shorter as a small amount of DNA is lost from each end. Telomeres are long stretches of "junk" DNA at each end of the chromosome that keep important bits of DNA from disappearing. When a cell's telomeres wear out, it stops dividing.
Can we guess someone’s age from how long their DNA is?
Unfortunately, it is not that easy. Everyone is born with different DNA lengths. This means that without knowing how long someone's DNA was at birth, you can only guess their age very roughly. However, if you knew how long the person's telomere was when they were born, you could more accurately guess their age.

read about binaural beats not about binaural waves .
While some studies have indicated that binaural beats can enhance some types of memory, others have found that they can potentially have a negative impact on memory.
Yet, it has been discovered that using binaural beats can help people focus and pay attention more intensely.
So, the answer of the Question is not yet clear . To determine whether binaural beats genuinely improve these memory and focus , in addition to your learning and memory, a lot more research is now required.

In fact, blood is the only source of nutrients and oxygen needed for neurons to survive and operate.However, there are certain substances in the blood that can be toxic to neurons if they are present in excessive amounts
