hi
the skin has the most cells
No, cell division rates can vary between different types of cells. Skin cells typically divide more frequently than brain cells. Skin cells are constantly replenishing and regenerating, whereas brain cells have a lower rate of division.
Injuries in the brain do not heal because brain cells cannot grow back. On the other hand body cells (skin) do grow back.
The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
They have many that we have: skin cells, muscle cells, brain cells, nerve cells. and bone cells.

Muscles,brain are so active. They need energy greatly
Gene expression is responsible for creating distinct sets of proteins in skin cells compared to brain cells.
The DNA in a turtle's brain cell and skin cell is fundamentally the same, as both cells originate from the same genetic material. However, they differ in gene expression; specific genes are activated in brain cells that are not expressed in skin cells, leading to distinct functions and characteristics. This differential gene expression is influenced by the cells' unique roles in the organism, with brain cells primarily involved in processing information and skin cells serving protective functions. Thus, while the underlying DNA is identical, the way it is used by the cells results in their different identities and roles.
brain via electrical signals. When a pin pricks your skin, it activates these nerve cells, sending signals to your brain to register the sensation of pain.
Gametes, such as eggs and sperm, are haploid, not diploid. Diploid would be somatic cells, such as skin cells or brain cells.
You will need to chick on these links to see the differences between heart, skin. brain and lung tissues.
