no, not really. you may not notice or feel, but your cells die out! now, before you panic, let me tell you, it is fine and normal to lose dead cells. you grow new skin cells. the only part of your body that can naever restore it's cells is the brain. once you lose a brain cell, you can never get a replacement.

No, not all of the cells in your body are the same. For example, if you take a neuron and compare it with a skin cell, they are obviously not in the same form. However, all cells do have the same genetic information throughout the body. If you take a nucleus of your cheek cells and of your liver cell, you can see that they have the exact same nucleic information in the DNA.
So what makes the cells in the body so distinct and different?
The cells in our body have different expressions to perform different functions.
In neurons, one genetic marker is expressed as where in the skin cell, the gene is not. This makes the cells specialized (specialization) and make able so that they can carry out their work.
To sum it up, are all the cells in your bodies the same?
-No and yes.
no because the cells have different genetic expression depending on what type of cell it is
yes because they all have the same genetic information.
Hope that helps.
no there is not one that is older than you
yes, this is true for somatic cells.
Old cells and/or stem cells.
this happens because new cells are made in your body every.the old cells then die and are nolonger in your body . Over 1000 cells are in your body. they are new cellls in your body every day. New ones are made so it like a new baby.
a muscle. Tissue is any grouping of cells.
When a human fetus is in its mother's womb, all of the cells that start to develop in it are stem cells. stem cells can form into any other type cell found in the human body. as the fetus continues to develop, the stem cells will change into whatever cells the baby needs(i.e., they will change into all the cells found in the human body)
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.
The human body continually sheds dead skin cells, and re-grows new ones. So at any given time, a person's body has both new and old skin cells.
Old cells and/or stem cells.
no
because it sheds of old skin cells in your body
white blood cells
Haploid cells are not found in any part of the body except the ovaries or testes.
your body's cells run out
Sounds like our old friends the White Blood cells!
Body cells, somatic cells, basically any type of cells except sex cells.
Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.
Sex cells have 1/2 the number of chromosomes than body cells. In humans that is 23.
The definition of somatic cells is any cell, with the exception of reproductive cells of eggs and sperm, in a living organism. Somatic cells are diploid cells that compose the organs and tissues.
