no, not all the cells in the body are the same, they are all very different as they have different functions. A nervecell looks way different than a muscle cell and so on.
no
no
Somatic cells are body cells which are important part of the body's multicellularity and function. So they should have same DNA code in order to maintain a balance in the functioning of the body. And except sex cells (gamates) all the cells of human body (i.e. somatic cells) have the same DNA code. Another reason for this is mitosis. As body cells arise from mitosis, the division is conservative and doesn't involve any process of inducing variation in the cells, hence all the cells originating from it have the same DNA code.
Skin cells are important to other body cells because they all have to work together. In the same body just doing different jobs.
No.
Most cells are somatic (body) cells. The only exception is the gametes.
Because you touch yourself at night
Each and every cell in your body is different no matter what they look like. For example, white blood cells fight virus's and bacteria and protect the body from the virus's then a red blood cell, which is a cell that carries oxygen around the body and keeps the body fully energized and living.
All normal cells in the human body have the same number of chromosomes because of the process of mitosis. Each cell is a clone.
no because they are placed in different spots inside of your body, and if all of your cells did the same thing,your body would only have one function.
There are many autoimmune diseases which all does the same thing: destroying their own body.
the DNA should be the same in all cells as long as they part of the same organism.
