The stomach releases a chemical signal to the brain, which the brain therefore sends it to the nervous system which we feel the so-called "Hungry feeling"
mouth
the mouth is a part of the digestive system. cells in the digestive system are the most quick cells to be replaced. so taking a sample from it won't cause much problem, unlike you take it by cutting open your leg and taking a sample. the lining of the cheek is the easiest to take rather than having to take it from somewhere else. and the cells in the mouth are alive, unlike skin cells that are dead. conclusion : it is the safest, fastest way to get live animal cells
Generally Human Cheek cells (as with skin cells) are dead on the outermost layers, and still alive on the deeper layers. So the cheek cells are dead even before you take them out of your mouth.
Mouth is a organ of eukariyotes.So they have a nucleus.
All cells have DNA in them. If you take cells from your mouth and finger they would have the same genetic code.
ears eyes mouth nose teeth hands feet
No, sorry that's quite false. For a great example consider a great white shark. It's a cartilaginous fish.
because once the cell is exposed to oxygen it oxidizes causing to cellular structures to spread out on a slide
They don't, you have it the wrong way round. The structures in the mouth of a frog are adaptations that help it compete and SURVIVE. Structure do not lead to adaptation, structures ARE adaptations.
mouth
el hocico or la boca del animal = the animal's mouth la boca de un animal = an animal's mouth la boca de los animales = the animals' mouth
protostome
It's just called the mouth of the hungry animal.
All over the animal everything in the animal is made up of cells the fur tissue eyes mouth and nose. Sooo to answer your question the cella aren't found in just one area of the body but all over the organism (animal).
